- The mycalesine butterfly genus Heteropsis Westwood, 1850 (Satyrinae: Mycalesina) has recently been conceived to be represented in three major palaeotropical regions (Madagascar, Africa and Asia), but there has been no formal taxonomic treatment covering this entire group. Studies aimed at understanding the evolutionary success of Mycalesina in the Old World tropics have been hampered by the lack of both a robust phylogeny and a stable nomenclature for this satyrine subtribe. Here, we present a well-supported molecular phylogeny based on 10 genes and 133 exemplar taxa, representing almost all known species groups of Heteropsis (s.l.), and including all but four known species in Madagascar. We also combine sequences of the exemplars with a morphological matrix of 428 characters. The widespread 'Heteropsis clade' is confirmed as monophyletic, but lineages in different geographic regions also form endemic and well-supported clades with deep divergences among them. Here we establish this group as comprising three genera, Heteropsis (Malagasy region only), Telinga Moore, 1880 (Asia), and Brakefieldia gen.n. (Africa). We recover the genera Telinga and Brakefieldia as sisters with high support. Each genus is taxonomically characterized and a revised synonymic checklist is appended with new combinations and some changes in rank. With a well-resolved topology and updates to the taxonomy of the group, researchers are now in a position to explore the drivers of the spectacular radiation of the group, notably in Madagascar, where the highest phenotypic and species diversity occurs.

- Abstract. A full taxonomic revision is presented of the Holarctic diving beetle genus Acilius Leach (Coleoptera: Dytiscidae) belonging to the subfamily Dytiscinae and tribe Aciliini. Acilius confusussp.n., previously confused with Acilius fraternus (Harris), is described from north-eastern U.S.A. Acilius latiusculus LeConte and Acilius simplex LeConte are new synonyms of Acilius abbreviatus Aubé. Lectotypes are designated for the following names: A. abbreviatus, A. semisulcatus Aubé, A. fraternus, A. guerryi d'Olsoufieff, A. sinensis Peschet, A. duvergeri Gobert, A. brevis Aubé, A. fasciatus (De Geer), A. maccullochii (Kirby), A. tomentosus Motschulsky, A. sulcatus blancki Peyerimhoff, A. subimpressus Motschulsky and A. laevisulcatus Motschulsky. In total, six Palaearctic and seven Nearctic species are recognized, none of which is Holarctic in distribution. Each species is presented with a diagnosis, full description, habitat preferences, conservation assessments, distribution data and a comprehensive bibliography. Distribution data are presented with a map and a list of countries, or for Nearctic and eastern Palaearctic species, states or larger provinces. A key to all Acilius species is included and each is fully illustrated. The general biology and a taxonomic history of the genus are provided. Acilius abbreviatus and A. semisulcatus are found to hybridize in a narrow zone through middle British Columbia and south-western Alberta, geographically comparable with a previously recognized hybrid zone of several other insect species pairs. More than 5000 specimens were examined.

Forskningsöversikt (refereegranskat)abstract
- The Lanceocercata are a clade of stick insects (Phasmatodea) that have undergone an impressive evolutionary radiation in Australia, New Caledonia, the Mascarene Islands and areas of the Pacific. Previous research showed that this clade also contained at least two of the nine New Zealand stick insect genera. We have constructed a phylogeny of the Lanceocercata using 2277 bp of mitochondrial and nuclear DNA sequence data to determine whether all nine New Zealand genera are indeed Lanceocercata and whether the New Zealand fauna is monophyletic. DNA sequence data were obtained from mitochondrial cytochrome oxidase subunits I and II and the nuclear large subunit ribosomal RNA and histone subunit 3. These data were subjected to Bayesian phylogenetic inference under a partitioned model and maximum parsimony. The resulting trees show that all the New Zealand genera are nested within a large New Caledonian radiation. The New Zealand genera do not form a monophyletic group, with the genus Spinotectarchus Salmon forming an independent lineage from the remaining eight genera. We analysed Lanceocercata apomorphies to confirm the molecular placement of the New Zealand genera and to identify characters that confirm the polyphyly of the fauna. Molecular dating analyses under a relaxed clock coupled with a Bayesian extension to dispersal-vicariance analysis was used to reconstruct the biogeographical history for the Lanceocercata. These analyses show that Lanceocercata and their sister group, the Stephanacridini, probably diverged from their South American relatives, the Cladomorphinae, as a result of the separation of Australia, Antarctica and South America. The radiation of the New Caledonian and New Zealand clade began 41.06 million years ago (mya, 29.05-55.40 mya), which corresponds to a period of uplift in New Caledonia. The main New Zealand lineage and Spinotectarchus split from their New Caledonian sister groups 33.72 (23.9-45.62 mya) and 29.9 mya (19.79-41.16 mya) and began to radiate during the late Oligocene and early Miocene, probably in response to a reduction in land area and subsequent uplift in the late Oligocene and early Miocene. We discuss briefly shared host plant patterns between New Zealand and New Caledonia. Because Acrophylla sensu Brock & Hasenpusch is polyphyletic, we have removed Vetilia Stal from synonymy with Acrophylla Gray.

Interrelationships and diversification of Argynnis Fabricius and Speyeria Scudder butterflies

Tidskriftsartikel (refereegranskat)abstract
- Diverse radiations of insects are often associated with adaptations to host plants, and well-resolved phylogenetic relationships are required to fully understand them. Palearctic Argynnis and related subgenera, together with North American Speyeria butterflies make up a radiation whose species hypotheses are confounded by shared wing colour patterns between sympatric populations of closely related recognized species. Previous studies of this group indicate that Speyeria is a lineage within Argynnis, but sampling in these studies has either involved too few Speyeria species or incomplete sampling of Argynnis species. Thus, no comprehensive phylogenetic analysis exists for all members that answers the question of monophyly of Speyeria, or other subgeneric taxa, and their relationship to Argynnis species. We completed a phylogenetic analysis of all North American Speyeria species and all but one species within Argynnis, using one mitochondrial (cytochrome c oxidase I, COI) and four nuclear genes [elongation factor 1 alpha (EF1α), wingless (WG), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and ribosomal protein S5 (RPS5)]. The results indicate three major lineages within Argynnis s.l.: two Palearctic and one containing both Palearctic and Nearctic species. In summary, the phylogenetic analyses suggest the need for reorganization into three natural groups: Argynnis, Fabriciana and Speyeria. Within each of these genera the phylogenetic hypothesis indicates an evolutionary history marked by rapid diversification and potential extinction, followed by ongoing lineage sorting. The position of North American Speyeria is nested within the Palearctic lineages, which indicates that the radiation began in Asia and was fuelled by existing Viola diversity in North America. Dating analyses of Viola and Speyeria corroborate this hypothesis. The current North American Speyeria species are mixed on the tree, indicating a recent and ongoing radiation. These results provide needed clarity on the evolution of this group, which contains species of conservation concern.

Tidskriftsartikel (refereegranskat)abstract
- The diverse, largely Neotropical subtribe Euptychiina is widely regarded as one of the most taxonomically challenging groups among all butterflies. Over the last two decades, morphological and molecular studies have revealed widespread paraphyly and polyphyly among genera, and a comprehensive, robust phylogenetic hypothesis is needed to build a firm generic classification to support ongoing taxonomic revisions at the species level. Here, we generated a dataset that includes sequences for up to nine nuclear genes and the mitochondrial COI ‘barcode’ for a total of 1280 specimens representing 449 described and undescribed species of Euptychiina and 39 out-groups, resulting in the most complete phylogeny for the subtribe to date. In combination with a recently developed genomic backbone tree, this dataset resulted in a topology with strong support for most branches. We recognize eight major clades that each contain two or more genera, together containing all but seven Euptychiina genera. We provide a summary of the taxonomy, diversity and natural history of each clade, and discuss taxonomic changes implied by the phylogenetic results. We describe nine new genera to accommodate 38 described species: Lazulina Willmott, Nakahara & Espeland, gen.n., Saurona Huertas & Willmott, gen.n., Argentaria Huertas & Willmott, gen.n., Taguaiba Freitas, Zacca & Siewert, gen.n., Xenovena Marín & Nakahara, gen.n., Deltaya Willmott, Nakahara & Espeland, gen.n., Modica Zacca, Casagrande & Willmott, gen.n., Occulta Nakahara & Willmott, gen.n., and Trico Nakahara & Espeland, gen.n. We also synonymize Nubila Viloria, Andrade & Henao, 2019 (syn.n.) with Splendeuptychia Forster, 1964, Macrocissia Viloria, Le Crom & Andrade, 2019 (syn.n.) with Satyrotaygetis Forster, 1964, and Rudyphthimoides Viloria, 2022 (syn.n.) with Malaveria Viloria & Benmesbah, 2020. Overall, we revised the generic placement of 79 species (74 new generic combinations and five revised combinations), and as a result all but six described species of Euptychiina are accommodated within 70 named, monophyletic genera. For all newly described genera, we provide illustrations of representative species, drawings of wing venation and male and (where possible) female genitalia, and distribution maps, and summarize the natural history of the genus. For three new monotypic genera, Occulta gen.n., Trico gen.n. and Xenovena gen.n. we provide a taxonomic revision with a review of the taxonomy of each species and data from examined specimens. We provide a revised synonymic list for Euptychiina containing 460 valid described species, 53 subspecies and 255 synonyms, including several new synonyms and reinstated species.

Quasimodoana, a new Holarctic genus of eucoiline wasps (Hymenoptera, Cynipoidea, Figitidae), with a phylogenetic analysis of related genera

Tidskriftsartikel (refereegranskat)abstract
- A new Holarctic genus, Quasimodoana gen.n. is described for the Palearctic eucoiline wasp Eucoila decipiens Förster, 1869, as Quasimodoana decipiens comb.n. A lectotype is designated for this species. A new North American species is described here as Quasimodoana gibba sp.n. As the new genus has similarities with several eucoiline genera, belonging to two related but distinct lineages, a phylogenetic analysis was carried out, based on 83 morphological characters. The two lineages included in the analysis are referred to here under the tribal names of Eucoilini and Trichoplastini stat.nov. We discuss reasons for adopting available tribal names (rather than 'informal genus groups'), and Trichoplastini is removed from synonymy with Eucoilini. The phylogenetic analysis places Quasimodoana unambiguously within Eucoilini, as a sistergroup to the Trybliographa complex. However, there is only weak support for the monophyly of Eucoilini and for the hypothesized sistergroup relationship between Eucoilini and Trichoplastini.

Unexpected distribution patterns of Carduiceps feather lice (Phthiraptera: Ischnocera: Philopteridae) on sandpipers (Aves: Charadriiformes: Scolopacidae)

Tidskriftsartikel (refereegranskat)abstract
- The louse genus Carduiceps Clay & Meinertzhagen, 1939 is widely distributed on sandpipers and stints (Calidrinae). The current taxonomy includes three species on the Calidrinae (Carduiceps meinertzhageni, Carduiceps scalaris, Carduiceps zonarius) and four species on noncalidrine hosts. We estimated a phylogeny of four of the seven species of Carduiceps (the three mentioned above and Carduiceps fulvofasciatus) from 13 of the 29 hosts based on three mitochondrial loci, and evaluated the relative importance of flyway differentiation (same host species has different lice along different flyways) and flyway homogenization (different host species have the same lice along the same flyway). We found no evidence for either process. Instead, the present, morphology-based, taxonomy of the genus corresponds exactly to the gene-based phylogeny, with all four included species monophyletic. Carduiceps zonarius is found both to inhabit a wider range of hosts than wing lice of the genus Lunaceps occurring on the same group of birds, and to occur on Calidris sandpipers of all sizes, both of which are unexpected for a body louse. The previously proposed family Esthiopteridae is found to be monophyletic with good support. The concatenated dataset suggests that the pigeon louse genus Columbicola may be closely related to the auk and diver louse genus Craspedonirmus. These two genera share some morphological characters with Carduiceps, but no support was obtained for grouping these three genera together. Based on mitochondrial data alone, the relationships among genera within this proposed family cannot be properly assessed, but some previously suggested relationships within this proposed family are confirmed.

Phylogenomic analysis of protein-coding genes resolves complex gall wasp relationships

Tidskriftsartikel (refereegranskat)abstract
- Gall wasps (Hymenoptera: Cynipidae) comprise 13 distinct tribes whose interrelationships remain incompletely understood. Recent analyses of ultra-conserved elements (UCEs) represent the first attempt at resolving these relationships using phylogenomics. Here, we present the first analysis based on protein-coding sequences from genome and transcriptome assemblies. Unlike UCEs, these data allow more sophisticated substitution models, which can potentially resolve issues with long-branch attraction. We include data for 37 cynipoid species, including two tribes missing in the UCE analysis: Aylacini (s. str.) and Qwaqwaiini. Our results confirm the UCE result that Cynipidae are not monophyletic. Specifically, the Paraulacini and Diplolepidini + Pediaspidini fall outside a core clade (Cynipidae s. str.), which is more closely related to the insect-parasitic Figitidae, and this result is robust to the exclusion of long-branch taxa that could mislead the analysis. Given this, we here divide the Cynipidae into three families: the Paraulacidae stat. prom., Diplolepididae stat. prom. and Cynipidae (s. str.). Our results suggest that the Eschatocerini are the sister group of the remaining Cynipidae (s. str.). Within the Cynipidae (s. str.), the Aylacini (s. str.) are more closely related to oak gall wasps (Cynipini) and some of their inquilines (Ceroptresini) than to other herb gallers (Aulacideini and Phanacidini), and the Qwaqwaiini likely form a clade together with Synergini (s. str.) and Rhoophilini. Several alternative scenarios for the evolution of cynipid life histories are compatible with the relationships suggested by our analysis, but all are complex and require multiple shifts among parasitoids, inquilines and gall inducers.

- The subgenera of Wiedemannia are poorly defined and, as such, most recently described species are not assigned to a subgenus or have been assigned to a subgenus without explanation. In this study we perform a molecular phylogenetic analysis to elucidate relationships within the genus Wiedemannia. We sequenced two mitochondrial (cytochrome oxidase c subunit I and cytochrome β) and two nuclear (carbomoylphosphate synthase domain of rudimentary and elongation factor‐1α) gene fragments to reconstruct phylogenetic relationships among the subgenera Chamaedipsia, Eucelidia, Philolutra, Pseudowiedemannia, Roederella and Wiedemannia (s.s.) using both Bayesian inference and maximum likelihood approaches. The genus was found to be monophyletic, but most of the subgenera were not. We propose eliminating the present subgeneric division altogether. Molecular dating using a log‐normal clock model and calibration with fossil species indicated that Wiedemannia diversified about 48 Ma, while there was still land connectivity between Europe and Asia with North America. Wiedemannia has a near‐worldwide distribution apart from the Australasian and Neotropical regions and Antarctica, with greatest species richness in the western Palaearctic, especially the Mediterranean region. Molecular phylogenetics support more recent morphological studies. The subgenera of Wiedemannia are invalid and rejected. Biogeographical data suggest potential hotspots, and the current distribution is discussed.

Tidskriftsartikel (refereegranskat)abstract
- We inferred the phylogenetic relationships among 58 genera of Sericostom-atoidea, representing all previously accepted families as well as genera that were notplaced in established families. The analyses were based on ve fragments of the proteincoding genes carbamoylphosphate synthetase (CPSase of CAD), isocitrate dehydroge-nase (IDH), Elongation factor 1a (EF-1a), RNA polymerase II (POL II) and cytochromeoxidase I (COI). The data set was analysed using Bayesian methods with a mixedmodel, , and parsimony. The various methods generated slightly different resultsregarding relationships among families, but the shared results comprise support for: (i)a monophyletic Sericostomatoidea; (ii) a paraphyletic Parasericostoma due to inclusionof Myotrichia murina, leading to synonymization of Myotrichia with Parasericostoma;(iii) a polyphyletic Sericostomatidae, which is divided into two families, Sericostom-atidae sensu stricto and Parasericostomatidae fam.n.; (iv) a polyphyletic Helicophidaewhich is divided into Helicophidae sensu stricto and Heloccabucidae fam.n.; ( v) hypoth-esized phylogenetic placement of the former incerta sedis genera Ngoya, Seselpsycheand Karomana; (vi) a paraphyletic Costora (Conoesucidae) that should be divided intoseveral genera after more careful examination of morphological data; (vii) reinstatementof Gyrocarisa as a valid genus within Petrothrincidae. A third family, Ceylanopsychi-dae fam.n., is established based on morphological characters alone. A hypothesis ofthe relationship among 14 of the 15 families in the superfamily is presented. A key tothe families is presented based on adults (males). Taxonomic history, diagnosis, habitatpreference and distribution data for all sericostomatoid families are presented.

Tidskriftsartikel (refereegranskat)abstract
- Amphipyrinae have long been a catchall taxon for Noctuidae, with most members lacking discernible morphological synapomorphies that would allow their assignment to one of the many readily diagnosable noctuid subfamilies. Here data from seven gene regions (> 5500 bp) for more than 120 noctuid genera are used to infer a phylogeny for Amphipyrinae and related subfamilies. Sequence data for 57 amphipyrine genera – most represented by the type species of the genus – are examined. We present here the first large-scale molecular phylogenetic study of Amphipyrinae and the largest molecular phylogeny of Noctuidae to date; several proposed nomenclatural changes for well-supported results; and the identification of areas of noctuid phylogeny where greater taxon sampling and/or genomic-scale data are needed. Adult and larval morphology, along with life-history traits, for taxonomic groupings most relevant to the results are discussed. Amphipyrinae are significantly redefined; many former amphipyrines, excluded as a result of these analyses, are reassigned to other noctuid subfamily-level taxa. Four genera, Chamaeclea Grote, Heminocloa Barnes & Benjamin, Hemioslaria Barnes & Benjamin and Thurberiphaga Dyar, are transferred to the tribe Chamaecleini Keegan & Wagner tribe n. in Acontiinae. Stiriina is elevated to Stiriinae rev. stat., Grotellina is elevated to Grotellinae rev. stat. and Annaphilina is elevated to Annaphilini rev. stat. Acopa Harvey is transferred to Bryophilinae, Aleptina Dyar is transferred to Condicinae, Leucocnemis Hampson and Oxycnemis gracillinea (Grote) are transferred to Oncocnemidinae, Nacopa Barnes & Benjamin is transferred to Noctuinae and Narthecophora Smith is transferred to Stiriinae. Azenia Grote (and its subtribe Azeniina), Cropia Walker, Metaponpneumata Möschler, Sexserrata Barnes & Benjamin and Tristyla Smith are transferred to Noctuidae incertae sedis. Hemigrotella Barnes & McDunnough (formerly in subtribe Grotellina) is retained in Amphipyrinae. Argentostiria Poole and Bistica Dyar are retained in Stiriini but removed from incertae sedis position.

Phylogenetic relationships, biogeography and diversification of Coenonymphina butterflies (Nymphalidae : Satyrinae): intercontinental dispersal of a southern Gondwanan group?

Tidskriftsartikel (refereegranskat)abstract
- The origins, evolutionary history and diversification of the Australian butterfly fauna are poorly known and uncertain. Two competing hypotheses have been proposed to explain the occurrence of butterflies on this isolated continental landmass. The common view is that all Australian butterflies entered the continent relatively recently from the northern hemisphere via Southeast Asia and/or mainland New Guinea (i.e. northern dispersal origin hypothesis). The alternative view is that part or all of the Australian butterfly fauna ultimately evolved in remnant or Southern Gondwana when Australia was connected to South America through Antarctica (i.e. Southern Gondwanan origin hypothesis). However, robust phylogenies with strong support for monophyly are lacking for the majority of Australian endemic butterfly lineages, thereby precluding determination of their systematic relationships and hence their geographic origins. Here, we use molecular data to reconstruct phylogenetic relationships of the globally distributed butterfly subtribe Coenonymphina (Satyrinae: Satyrini). This group represents a major component of the butterfly fauna of the wider Australasian region, with 19 genera and 71 species endemic to the region. Dating estimates extrapolated from secondary calibration sources indicate that the subtribe arose c. 48 Ma (95% credibility interval, 52–42 Ma), and the crown group first diverged in the Eocene (c. 44 Ma, 95% credibility interval 51–37 Ma). Rapid speciation events subsequently followed around the Eocence–Oligocene boundary, resulting in a near-hard polytomy comprising short basal branches with nodes that are difficult to resolve. Based on strongly supported phylogenetic relationships and estimates of divergence times, we conclude that the group probably had its origin in the fragment of Southern Gondwana consisting of Australia, Antarctica and South America. However, we are unable to rule out the northern dispersal scenario, particularly as Coenonymphina are closely related to a set of predominantly Asian lineages. Dispersal and extinction events following the final break-up of Gondwana have played a pivotal role in shaping the extant distributions of the group.

- We studied the historical biogeography of a group of butterflies in the Holarctic region belonging to the genus Coenonympha (Nymphalidae: Satyrinae: Coenonymphina), based on a phylogenetic hypothesis estimated from three genes. The genus is distributed mainly in the Palaearctic region, with two species extending into the Nearctic region. The tree is generally well supported and shows that Coenonympha is paraphyletic with respect to Lyela (syn.n.) and Triphysa (syn.n.), and we hence synonymize the latter two with Coenonympha. Within Coenonympha we identify three species groups, the tullia, glycerion and hero groups. The North American tullia exemplars are not sister to the Eurasian ones. A diva analysis indicates that the ancestor of the group was present in the Central Palaearctic or Central Palaeartic + Western Palaearctic or Central Palaearctic + Eastern Palaearctic. We conclude that the most likely origin of extant members of Coenonympha was in the Central Asian mountains. The tullia and hero groups started diverging in Europe following dispersal into the region. There have been two independent colonizations into Africa. The drying up of the Mediterranean during the Messinian period probably played an important role, allowing colonization into the Mediterranean islands and Africa.

Tidskriftsartikel (refereegranskat)abstract
- The slug moth family Limacodidae is a cosmopolitan group of economic importance, but its higher level systematics remains poorly understood. Here, we present a robust, higher level phylogenetic framework for Palaearctic and Indomalayan members of the family using sequence capture data of 148 nuclear protein-coding and 13 mitochondrial markers from 145 samples of 126 species in 67 genera representing all five morphologically delineated limacodid lineages. Our results strongly support the monophyly of Limacodidae in which six major clades are recognized. The relationships among these clades are revealed, with Phrixolepia-clade being the most basal group followed by Apoda-clade, Euphlyctinides-clade, Cania-clade and Phlossa-clade + Parasa-clade, respectively. We also add publicly available DNA barcode sequences from additional species worldwide to this phylogenetic framework to infer the most completely sampled phylogeny of Limacodidae to date. Our work provides a major step towards understanding the systematics and evolution of slug moths.

Phylogenomic species delimitation of the twisted-winged parasite genus Stylops (Strepsiptera)

Tidskriftsartikel (refereegranskat)abstract
- The twisted-winged parasite genus Stylops has a history of different species concepts with varying host specificity resulting in diverse species diversity estimates in different regions of the Holarctic. The adoption of a supergeneralist species concept in Europe, proposing synonymization of all Western Palaearctic Stylops species, did not facilitate taxonomic clarity and obscured the available life-history data in the region for decades. Lack of molecular data has allowed divergent opinions on species hypotheses and little opportunity for evaluating them in this morphologically challenging genus. To solve these discrepancies and gain novel information about host associations, we applied whole-genome sequencing to 163 specimens, representing a significant portion of putative European species. We evaluate the existing and conflicting species hypotheses with molecular species delimitation using Species bOundry Delimitation using Astral (SODA) and use a maximum likelihood phylogeny to investigate host associations of the species. Furthermore, we evaluate the effect of a number of loci used in SODA for the number of inferred species. We find justification for synonymization of multiple species and indications of undescribed species, as well as new host-parasite relationships. We show that the number of inferred species in SODA is exceedingly and positively correlated with the number of loci used, urging for cautious application. The results of our study bring clarity to the Western Palaearctic species diversity of Stylops. Furthermore, the comprehensive molecular dataset generated in this study will be a valuable resource for future studies on Stylops and the evolution of parasites in general.

- The twisted-winged parasite genus Stylops has a history of different species concepts with varying host specificity resulting in diverse species diversity estimates in different regions of the Holarctic. The adoption of a supergeneralist species concept in Europe, proposing synonymization of all Western Palaearctic Stylops species, did not facilitate taxonomic clarity and obscured the available life-history data in the region for decades. Lack of molecular data has allowed divergent opinions on species hypotheses and little opportunity for evaluating them in this morphologically challenging genus. To solve these discrepancies and gain novel information about host associations, we applied whole-genome sequencing to 163 specimens, representing a significant portion of putative European species. We evaluate the existing and conflicting species hypotheses with molecular species delimitation using Species bOundry Delimitation using Astral (SODA) and use a maximum likelihood phylogeny to investigate host associations of the species.

- Recent advances in obtaining reduced representation libraries for next-generation sequencing permit phylogenomic analysis of species-rich, recently diverged taxa. In this study, we performed sequence capture with homemade PCR-generated probes to study diversification among closely related species in a large insect genus to examine the utility of this method. We reconstructed the phylogeny of Neptis Fabricius, a large and poorly studied nymphalid butterfly genus distributed throughout the Old World. We inferred relationships among 108 Neptis samples using 89 loci totaling up to 84 519 bp per specimen. Our taxon sample focused on Palearctic, Oriental and Australasian species, but included 8 African species and outgroups from 5 related genera. Maximum likelihood and Bayesian analyses yielded identical trees with full support for almost all nodes. We confirmed that Neptis is not monophyletic because Lasippa heliodore (Fabricius) and Phaedyma amphion (Linnaeus) are nested within the genus, and we redefine species groups for Neptis found outside of Africa. The statistical support of our results demonstrates that the probe set we employed is useful for inferring phylogenetic relationships among Neptis species and likely has great value for intrageneric phylogenetic reconstruction of Lepidoptera. Based on our results, we revise the following two taxa: Neptis heliodore comb. rev. and Neptis amphion comb. rev.

Species limits in butterflies (Lepidoptera: Nymphalidae): reconciling classical taxonomy with the multispecies coalescent

- Species delimitation is at the core of biological sciences. During the last decade, molecular-based approaches have advanced the field by providing additional sources of evidence to classical, morphology-based taxonomy. However, taxonomy has not yet fully embraced molecular species delimitation beyond threshold-based, single-gene approaches, and taxonomic knowledge is not commonly integrated into multilocus species delimitation models. Here we aim to bridge empirical data (taxonomic and genetic) with recently developed coalescent-based species delimitation approaches. We use the multispecies coalescent model as implemented in two Bayesian methods (dissect/stacey and bp&p) to infer species hypotheses. In both cases, we account for phylogenetic uncertainty (by not using any guide tree) and taxonomic uncertainty (by measuring the impact of using a priori taxonomic assignments to specimens). We focus on an entire Neotropical tribe of butterflies, the Haeterini (Nymphalidae: Satyrinae). We contrast divergent taxonomic opinion - splitting, lumping and misclassifying species - in the light of different phenotypic classifications proposed to date. Our results provide a solid background for the recognition of 22 species. The synergistic approach presented here overcomes limitations in both traditional taxonomy (e.g. by recognizing cryptic species) and molecular-based methods (e.g. by recognizing structured populations, and not raising them to species). Our framework provides a step forward towards standardization and increasing reproducibility of species delimitations.

- Museum collections around the world contain billions of specimens, including rare and extinct species. If their genetic information could be retrieved at a large scale, this would dramatically increase our knowledge of genetic and taxonomic diversity information, and support evolutionary, ecological and systematic studies. We here present a target enrichment kit for 2953 loci in 1753 orthologous nuclear genes + the barcoding region of cytochrome C oxidase 1, for Lepidoptera and demonstrate its utility to obtain a large number of nuclear loci from dry, pinned museum material collected from 1892 to 2017. We sequenced enriched libraries of 37 museum specimens across the order Lepidoptera, many from higher taxa not yet included in high-throughput molecular studies, showing that our kit can be used to generate comparable data across the order, and provides resolution both for shallower and deeper nodes. The filtered datasets (172 taxa, 234 464 amino acid positions and corresponding nucleotides from 1835 CDS regions) were used to infer a phylogeny of Lepidoptera, which is largely congruent in topology to recent phylogenomic studies, but with the addition of some key taxa. We furthermore present our TEnriAn (Target Enrichment Analysis) workflow for processing and combining target enrichment, transcriptomic and genomic data.

First comprehensive higher level phylogeny of Zygaenidae (Lepidoptera) including estimated ages of the major lineages and a review of known zygaenid fossils

Tidskriftsartikel (refereegranskat)abstract
- Zygaenidae, also known as burnet, forester, smoky, or leaf skeletonizer moths, are a family of mainly diurnal moths well known for their aposematic colouration and the ability to release hydrogen cyanide as a defence mechanism. So far, few attempts have been made to understand the evolutionary history of the global zygaenid fauna. Here, we inferred the most comprehensive molecular phylogeny for Zygaenidae to date and estimated the lineage timing-of-divergence with a Bayesian approach. Building on earlier work, we significantly increased the taxon and gene sampling for the family, which here included data from 30 gene fragments, recovered from public databases or newly sequenced, for almost 30% of the species representing 92 genera (49%) and all five subfamilies. We recovered strong support for the monophyly of Zygaenidae, Chalcosiinae, and Zygaeninae. Procridinae were recovered as monophyletic with low support, whereas the monophyly of Callizygaeninae remains untested as we sampled only one of the two genera. In the core dataset, we recovered Procridinae as sister to Callizygaeninae + Chalcosiinae. This large clade is the sister lineage to Zygaeninae. The position of Inouelinae could not be resolved. The lineage leading to the extant Zygaenidae appears to have diverged in Late Cretaceous (ca. 86 Ma), while the divergence among the subfamilies occurred several million years before the Cretaceous–Paleogene mass extinction event (ca. 66 Ma). Additionally, we provide a review of known fossil Zygaenidae as Appendix S1. Our results form a strong basis for future studies of zygaenid biosystematics, including their ecology, evolution, and behaviour.

- Geometrid moths, the second largest radiation of Lepidoptera, have been the target of extensive phylogenetic studies. Those studies have flagged several problems in tree topology that have remained unanswered. We address three of those: (i) deep nodes of Geometridae (subfamilies Sterrhinae + Larentiinae, or Sterrhinae alone as sister to all other subfamilies), (ii) the taxonomic status of subfamily Orthostixinae and (iii) the systematic position of the genus Eumelea (classified in Desmobathrinae: Eumeleini or incertae sedis earlier). We address these questions by using a phylogenomic approach, a novel method on these moths, with up to 1000 protein-coding genes extracted from whole-genome shotgun sequencing data. Our datasets include representatives from all geometrid subfamilies and we analyse the data by using three different tree search strategies: partitioned models, GHOST model and multispecies coalescent analysis. Despite the extensive data, we found incongruences in tree topologies. Eumelea did not associate with Desmobathrinae as suggested earlier, but instead, it was recovered in three different phylogenetic positions, either as sister to Oenochrominae, Geometrinae or as sister to Oenochrominae + Geometrinae. Orthostixinae, represented by its type species, falls within Desmobathrinae. We propose the following taxonomic changes: we raise Eumeleini to subfamily rank as Eumeleinae stat. nov. and we treat Orthostixinae as a junior synonym of Desmobathrinae syn. nov.

- The most accepted taxonomic treatment of the New World sulphurs of the genus Phoebis Hübner, [1819] recognizes 16 species including those in the current synonyms Aphrissa and Rhabdodryas. This total conflicts with the results of several recent pierid DNA barcode studies across the Neotropics. We used a five-locus dataset to carry out species delimitation analyses using the coalescence-based method implemented in bpp software. After testing the resulting species hypotheses using marginal likelihood estimates, we inferred their phylogenetic relationships and performed an ancestral range reconstruction with biogeobears. Our analyses recovered two different hypotheses, 26 and 24 species, that scored the highest marginal likelihood estimate. Differences between these two hypotheses, when reconciled with barcode clusters and morphology, indicated that 24 is the most likely number of species. Phoebis neocypris stat. rev., Phoebis rurina stat. rev., Phoebis virgo stat. rev., Phoebis marcellina stat. rev., Phoebis thalestris stat. rev., and Phoebis rorata stat. rev. are raised to the species rank. We dated the crown age of Phoebis to the mid-Miocene, with the islands of the Greater Antilles as the most probable ancestral range. Three main clades of Phoebis diverged early in the evolutionary history of the genus, but most extant species-level diversity arose after the Pliocene–Pleistocene boundary. Our analyses recovered alternate range expansions and contractions, and dispersal from the islands to the continent and back, in the three main clades. Both sympatric and allopatric speciation seem to have shaped the current species richness.

Molecular phylogeny of north European Geometridae (Lepidoptera: Geometroidea)
-
Ingår i: Systematic Entomology. - 0307-6970.
-
Tidskriftsartikel (refereegranskat)abstract
- A comprehensive phylogeny of north European Geometridae is reconstructed using a two-step analytical pipeline. First, a phylogenomic backbone tree was inferred using a 117-species subset of geometrid moths and a 35-species set of outgroup taxa from eight other macroheteroceran families. The data matrix totalled 209,499 bp from 648 protein-coding loci obtained using anchored hybrid enrichment technique for sequencing. This backbone was used for constructing a larger phylogeny of Geometridae based on up to 11 ‘traditional’ protein-coding genes which were obtained for all 376 species of north European geometrids, complemented by 98 species from taxonomic key groups of Geometridae from other parts of the world. Our results largely corroborate earlier findings about higher classification of Geometridae, but new evidence nevertheless allows us to suggest several changes to the taxonomy. Lampropterygini Õunap & Nedumpally tribus nova and Pelurgini Õunap & Nedumpally tribus nova (both Larentiinae) are described. Epirranthini are regarded as a junior subjective synonym of Rumiini syn. n. Triphosini and Macariini are shown to be paraphyletic within their current limits. Costaconvexa Agenjo is transferred from Xanthorhoini to Epirrhoini new tribe association, Artiora Meyrick from Ennomini incertae sedis to Boarmiini new tribe association, Selenia Hübner from Ennominae incertae sedis to Epionini new tribe association and Epirranthis Hübner from Epirranthini to Rumiini new tribe association. Ochyria Hübner stat. rev. is revived from synonym of Xanthorhoe Hübner as a valid genus and Epelis Hulst stat. rev. and Speranza Curtis stat. rev. from synonyms of Macaria Curtis as valid genera, leading to the following new or revised combinations: Ochyria quadrifasiata (Clerck) rev. comb., Epelis carbonaria (Clerck) comb. n., Speranza fusca (Thunberg) comb. n., Speranza artesiaria (Denis & Schiffermüller) rev. comb., Speranza brunneata (Thunberg) rev. comb., Speranza wauaria (Linnaeus) rev. comb., Speranza loricaria (Eversmann) rev. comb. Perizoma saxicola Tikhonov rev. comb. is transferred back to its original genus from Gagitodes Warren. Hydrelia Hübner, Xanthorhoe and Heliomata Grote & Robinson are shown to be paraphyletic within their current limits.

Molecular systematics of the arctiine tribe Syntomini (Lepidoptera, Erebidae)

Tidskriftsartikel (refereegranskat)abstract
- The Old World tribe Syntomini is the most neglected of the three major groups of the subfamily Arctiinae – the most megadiverse lineage (c. 11 000 species) of the superfamily Noctuoidea, comprising about a quarter of its entire species diversity. In none of the previous morphogenetic studies was Syntomini (which are often conspicuously spotted, aposematic moths) sampled adequately enough to provide information about the tribe's systematic diversity and relationships above species level. As such data are of crucial importance for a comprehensive understanding of arctiine diversity and evolution, we have investigated the relationships of the major lineages of Syntomini based on up to eight mitochondrial and nuclear genes and 91 species, representing 39 genera. We cover most of the known genera and major geographic regions, including, for the first time, Madagascar, where there is a significant syntomine radiation. We find that the thyretines, in particular, which are restricted to the Afrotropical region, are paraphyletic. As a result we propose to treat Thyretina syn.n. (Thyretini sensu Przybyłowicz, 2009) as an artificial assemblage and synonymize it under Syntomini. Thyretes Boisduval and Pseudothyretes Dufrane stand on their own close to the Madagascan radiation, whereas all but one of the Madagascan syntomines comprise a monophylum, with the genus Fletcherinia Griveaud instead being related to at least one species of Ceryx Wallengren in Africa. Also surprising from a biogeographical point of view is that the genus Dysauxes Hübner, which includes the European Handmaiden moth, is nested within the Madagascan radiation. Our study also makes it clear that much more detailed studies are needed to revise not only Ceryx from Asia and Africa but the Afrotropical syntomine genera, many of which do not form clades in our phylogenetic reconstruction, and to further inventory the diversity that is present in the Afrotropics. Based on our results, we consider Thyretarctia Strand stat. rev., Daphaenisca Kiriakoff stat.n. and Callobalacra Kiriakoff stat.n. as valid genera. We also move Anapisa Kiriakoff and return Meganaclia Aurivillius and Nacliodes Strand to Syntomini.

- A new genus of Neotropical Satyrinae butterflies, Viloriodes Pyrcz & Espeland gen. n. is described in the Pedaliodes Butler complex comprising 11–13 genera and more than 400 species. Support for the new genus is provided by a phylogenetic analysis based on target enrichment (TE) data including 618 nuclear loci with a total of 248,940 nucleotides, and the mitochondrial gene cytochrome oxidase subunit 1 (COI). Five species, whose DNA sequences were obtained by TE during this study, form a strongly supported clade sister to the large clade comprising Pedaliodes and four other genera. Complementary COI analysis confirms the monophyly of Viloriodes gen. n., with the above five plus eight other species clustering in highly supported clades in both Bayesian Inference and Maximum Likelihood analyses, and a TE + COI concatenated tree. Based on molecular and morphological data, 30 species are assigned to Viloriodes gen. n. The new genus can be recognized by a set of subtle morphological characteristics of colour patterns and male and female genitalia. An analysis of divergence times indicates that Viloriodes gen. n. and Steromapedaliodes Forster separated around 5.9 Mya. Viloriodes gen. n. has a wider geographic distribution than any other genus of the Pedaliodes complex, being found from central Mexico to northern Argentina and to the Guyana Shield, typically occurring at lower elevations than Pedaliodes.

- We present results of an eight-gene molecular study of the subfamily Acronictinae and related Noctuidae. Amphipyrinae are recovered as sister to Acronictinae, but with weak support - not surprisingly, the content of the two subfamilies has often been mixed in classifications. Balsinae, previously placed near Acronictinae or within Noctuinae, is recovered within an unresolved polytomy of Cuculliinae, Eustrotiinae, Raphiinae and Dilobinae. Gerbathodes Warren, Moma Hübner and Nacna Fletcher are excluded from Acronictinae. Three genera recently transferred into the subfamily - Cerma Hübner, Chloronycta Schmidt & Anweiler and Comachara Franclemont - are confirmed as acronictines. Lophonycta Sugi (the type genus of Lophonyctinae) is returned to the Acronictinae. Sinocharis Püngeler, formerly considered to be Acontiinae or as the basis of its own subfamily Sinocharinae, is nested within early diverging Acronictinae genera. Both subfamilies are formally synonymized: i.e. Lophonyctinae syn.n. and Sinocharinae syn.n. Nine acronictine genus-level taxa were found to nest within the nominate genus Acronicta Ochsenheimer: Eogena Guenée, Hyboma Hübner, Hylonycta Sugi, Jocheaera Hübner, Oxicesta Hübner, Simyra Ochsenheimer, Subacronicta Kozhanchikov, Triaena Hübner, and Viminia Chapman. Eogena, Oxicesta, and Simyra, currently treated as valid genera, nest within terminal clades of the genus Acronicta and are here subsumed within the genus: Eogena syn.n., Oxicesta syn.n. and Simyra syn.n. Four well-supported species groups within Acronicta are identified: the alni clade, the leporina clade, the nervosa clade and the psi clade. While many previous treatments have stated explicitly that Acronictinae lack abdominal scent brushes, or excluded genera with brushes from the subfamily, we show that well-developed brushes are present in three early diverging acronictine genera: Cerma, Lophonycta, and Sinocharis. We illustrate and describe the brushes of all three genera, and briefly review the taxonomic distribution of the anterior abdominal courtship brushes in Noctuidae, emphasizing the labile evolutionary distribution of these structures.

- The field of molecular phylogenetics is being revolutionized with next-generation sequencing technologies making it possible to sequence large numbers of genomes for non-model organisms ushering us into the era of phylogenomics. The current challenge is no longer how to get enough data, but rather how to analyse the data and how to assess the support for the inferred phylogeny. Here, we focus on one of the largest animal groups on the planet – butterflies and moths (order Lepidoptera), whose phylogeny remains unresolved despite several recent phylogenomic studies. In this study, we assess the potential causes and consequences of the conflicting phylogenetic hypotheses. With a dataset consisting of 331 protein-coding genes and the alignment length over 290,000 base pairs, including 200 taxa representing 83% of lepidopteran superfamilies, we compare phylogenetic hypotheses inferred from amino acid and nucleotide alignments. The resulting two phylogenies are discordant, especially with respect to the placement of the superfamily Gelechioidea, which is likely due to compositional bias and possible other model violations. Furthermore, we employed a series of analyses to dissect our dataset and demonstrate that there is sufficient phylogenetic signal to resolve much – but not all – of the lepidopteran tree of life. The relationships among superfamilies within Ditrysia, the most species rich lepidopteran clade containing 98% of the extant species, remain poorly resolved. We conclude that taxon sampling remains an issue even in phylogenomic analyses and recommend that poorly sampled highly diverse groups, such as Gelechioidea in Lepidoptera, should receive extra attention in the future.

- Despite being popular among amateur and professional lepidopterologists and posing great opportunities for evolutionary research, the phylogenetic relationships of tiger moths (Erebidae: Arctiinae) are not well resolved. Here we provide the first phylogenetic hypothesis for the subtribe Arctiina with the basic aim of clarifying the phylogenetic position of the Wood Tiger Moth Parasemia plantaginis Hübner, a model species in evolutionary ecology. We sampled 89 species in 52 genera within Arctiina s.l., 11 species of Callimorphina and two outgroup species. We sequenced up to seven nuclear genes (CAD, GAPDH, IDH, MDH, Ef1α, RpS5, Wingless) and one mitochondrial gene (COI) including the barcode region (a total of 5915 bp). Both maximum likelihood and Bayesian inference resulted in a well-resolved phylogenetic hypothesis, consisting of four clades within Arctiina s.s. and a clade comprising spilosomine species in addition to Callimorphina and outgroups. Based on our results, we present a new classification, where we consider the Diacrisia clade, Chelis clade, Apantesis clade, Micrarctia Seitz and Arctia clade as valid genera within Arctiina s.s., whereas Rhyparia Hübner syn.n. and Rhyparioides Butler syn.n. are synonymized with Diacrisia Hübner; Neoarctia Neumoegen & Dyar syn.n., Tancrea Püngeler syn.n., Hyperborea Grum-Grshimailo syn.n., Palearctia Ferguson syn.n., Holoarctia Ferguson syn.n., Sibirarctia Dubatolov syn.n. and Centrarctia Dubatolov syn.n. are synonymized with Chelis Rambur; Grammia Rambur syn.n., Orodemnias Wallengren syn.n., Mimarctia Neumoegen & Dyar syn.n., Notarctia Smith syn.n. and Holarctia Smith syn.n. are synonymized with Apantesis Walker; and Epicallia Hübner syn.n., Eucharia Hübner syn.n., Hyphoraia Hübner syn.n., Parasemia Hübner syn.n., Pericallia Hübner syn.n., Nemeophila Stephens syn.n., Ammobiota Wallengren syn.n., Platarctia Packard syn.n., Chionophila Guenée syn.n., Eupsychoma Grote syn.n., Gonerda Moore syn.n., Platyprepia Dyar syn.n., Preparctia Hampson syn.n., Oroncus Seitz syn.n., Acerbia Sotavalta syn.n., Pararctia Sotavalta syn.n., Borearctia Dubatolov syn.n., Sinoarctia Dubatolov syn.n. and Atlantarctia Dubatolov syn.n. are synonymized with Arctia Schrank, leading to 33 new genus-level synonymies. Our focal species Arctia plantaginis comb.n. is placed as sister to Arctia festiva comb.n., another widespread aposematic species showing wing pattern variation. Our molecular hypothesis can be used as a basis when adding more species to the tree and tackling interesting evolutionary questions, such as the evolution of warning signalling and mimicry in tiger moths.

- A multigene phylogenetic study was carried out to test current, mostly morphology-based hypotheses on Sterrhinae phylogeny with additional material included from further geographical areas and morphologically different lineages. A maximum likelihood analysis (11 molecular markers and 7665 bp) was conducted on 76 species and 41 genera using iq-tree software. The resulting phylogenetic hypothesis is well resolved and branches have high support values. Results generally agree with earlier hypotheses at tribal levels and support the hypothesis that Sterrhinae comprises two major lineages. Based on the molecular phylogeny and extensive morphological examination, nine tribes are considered valid and the following taxonomic changes are introduced to recognize monophyletic groups: Mecoceratini Guenée, 1858 (= Ametridini Prout, 1910) is transferred from Desmobathrinae to Sterrhinae, and it is considered valid at tribal level new classification; Haemaleini Sihvonen & Brehm is described as a new tribe and deemed sister to Scopulini + Lissoblemmini; Lissoblemmini Sihvonen & Staude is described as a new tribe and sister to Scopulini; Lythriini Herbulot, 1962 is now a junior synonym of Rhodometrini Agenjo, 1952 syn.n.; and Rhodostrophiini Prout, 1935 is now a junior synonym of Cyllopodini Kirby, 1892 syn.n. In addition, 48 taxa are transferred from other geometrid subfamilies to Sterrhinae, or within Sterrhinae from one tribe to another, or they are classified into a tribe for the first time, or a new genus classification is proposed. The results demonstrate the limited explanatory power of earlier classifications, particularly at the tribal level. This is probably a result of earlier classifications being based on superficial characters and biased towards the European and North American fauna. The species richness and distribution of Sterrhinae and its constituent tribes are reviewed, showing that the globally distributed Sterrhinae are most diverse in the Neotropics (31% of global fauna). They are species-rich in the Palaearctic (22%), Afrotropics (19%) and Indo-Malay (16%) regions, whereas they are almost absent in Oceania (1%). In terms of the described fauna, the most species-rich tribes are Scopulini (928 species), Sterrhini (876 species) and Cosymbiini (553 species), all of which have a cosmopolitan distribution. Mecoceratiini and Haemaleini are almost entirely Neotropical. Timandrini and Lissoblemmini, by contrast, are absent in the Neotropics. We present a revised classification of the global Sterrhinae fauna, which includes about 3000 putatively valid species, classified into nine tribes and 97 genera. Four genera are of uncertain position within Sterrhinae. Our results highlight the compelling need to include more genera from a global perspective in molecular phylogenetic studies, in order to create a stable global classification for this subfamily.

- The braconid subfamily Euphorinae is a large, cosmopolitan group of endoparasitoid wasps. The majority of species attack adult hosts, a strategy that is rare among parasitic wasps, but there are also many species that attack nymphs and larval stages. Euphorine hosts may belong to a variety of insect orders (Coleoptera, Hemiptera, Hymenoptera, Neuroptera, Psocoptera, Orthoptera and Lepidoptera) although most euphorine tribes are confined to Coleoptera. Here we investigate the phylogenetic relationships of the Euphorinae based on molecular data (3 kb of nucleotide data from four markers: 18S, 28S, CAD and COI) and propose a higher-level classification based upon the resulting phylogeny. We also infer the evolution of host associations and discuss the diversification of the Euphorinae. Results from both Bayesian inference and maximum-likelihood analysis show that the subfamily, as previously circumscribed, is paraphyletic. We propose that the subfamily be expanded to include the tribes Meteorini and Planitorini (Mannokeraia + Planitorus), so that it corresponds to a clade that is strongly supported as monophyletic in our analyses. Based on our results, a revised higher classification of the Euphorinae is proposed, in which 52 extant genera and 14 tribes are recognized. We reinstate the genus Microctonus belonging to the tribe Perilitini, and synonymize Ussuraridelus with Holdawayella, Sinuatophorus with Eucosmophorus. Furthermore, we propose the following tribal rearrangements: Spathicopis and Stenothremma are transferred to Perilitini; Tuberidelus, Eucosmopho- rus and Plynops to Cosmophorini; Ecclitura to Dinocampini; Chrysopophthorus, Holdawayella and Wesmaelia to Helorimorphini; Proclithroporus and Heia to Towne- silitini. The monotypic tribe Cryptoxilonini is synonymized with Cosmophorini. The genera Pygostolus and Litostolus are placed in a separate tribe, Pygostolini, previously recognized as a subtribe among the Centistini. Parsimony-based ancestral state recon- structions suggest that the ancestor of Euphorinae was a parasitoid of lepidopteran larvae, and that a host shift to larval Coleoptera occurred only in one clade of the Meteorini, some members of which secondarily shifted back to larval lepidopteran hosts. In the remainder of the subfamily, there was an initial shift from larval to adult coleopterans, followed by subsequent shifts to adults or larvae of Hemiptera, Hymenoptera, Neuroptera, Orthoptera and Psocoptera.

- Combining pheromone trapping and genetic analyses can be useful whentrying to resolve complexes of closely related insect taxa that are difficult to distinguishbased on morphological characters. Nearctic and Palearctic populations of the spruceseed moth, Cydia strobilella L., have been considered taxonomically synonymoussince 1983, but more recent work revealing distinct sex pheromones for Canadianand Swedish moths suggest that populations in the two regions belong to differentspecies. In order to test this hypothesis, we performed field trapping using differentpheromone lures at ten sites in North America, Europe and Asia, and reconstructedphylogenetic relationships among trapped moths using mitochondrial (cytochromeoxidase subunit I ) and nuclear (elongation factor 1 alpha) DNA sequence data.Trapping data and tree topologies for both genes revealed distinct pherotypes in NorthAmerica and Eurasia. A genetically distinct population from China was investigatedfurther with respect to its sex pheromone. Electrophysiological data indicated thatChinese females produce a deviant ratio of the sex pheromone components (dienicacetates) compared to Swedish females. However, trapping experiments in both areasrevealed a similar broad response profile in males to a wide range of acetate ratios,and these populations should be considered taxonomically synonymous. A previoussuggestion of an agonistic effect on the attraction of C. strobilella males in Swedenwhen adding the corresponding alcohols to the binary acetate blend was also testedin Sweden as well as in China, with no observed effect on attraction of males. In conclusion, our study demonstrates the great potential of using pheromone trappingas a tool for identification and delimitation of taxa within cryptic species complexes.Based on our data, Nearctic and Palearctic populations of C. strobilella should beconsidered different species, and C. youngana Kearfott stat. rev. is resurrected hereas valid name for North American populations, which was the case before the revisionin 1983.

- Museomics is a valuable approach that utilizes the diverse biobanks that are natural history museums. The ability to sequence genomes from old specimens has expanded not only the variety of interesting taxa available to study but also the scope of questions that can be investigated in order to further knowledge about biodiversity. Here, we present whole genome sequencing results from the enigmatic genus Whalleyana (comprising two species – occurring in drier biomes of Madagascar – previously placed in a monotypic superfamily, Whalleyanoidea), as well as from certain species of the families Callidulidae and Hyblaeidae (Calliduloidea and Hyblaeoidea, respectively). Library preparation was carried out on four museum specimens and one existing DNA extract and sequenced with Illumina short reads. De novo assembly resulted in highly fragmented genomes with the N50 ranging from 317 to 2078 bp. Mining of a manually curated gene set of 331 genes from these draft genomes had an overall gene recovery rate of 64–90%. Phylogenetic analysis places Whalleyana as sister to Callidulidae and Hyblaea as sister to Pyraloidea. Since the former sister-group relationship turns out to be also supported by ten morphological synapomorphies, we propose to formally assign the Whalleyanidae to the superfamily Calliduloidea. These results highlight the usefulness of not only museum specimens but also existing DNA extracts, for whole genome sequencing and gene mining for phylogenomic studies.

- Empidoidea represent a large and diverse superfamily of true flies, and to date no stable hypothesis on the phylogeny exists. Previous classifications have been based on morphological data and the relationships among several groups are still unknown. Using the mitochondrial genes cytochrome oxidase c subunit I (COI) and cytochrome β (Cytβ) and the nuclear genes carbomoylphosphate synthase domain of rudimentary (CAD), elongation factor‐1α (EF‐1α) and isocitrate dehydrogenase (IDH) in a Bayesian analysis, we tested the support of higher taxonomic groups within this large superfamily of flies. We re‐evaluated previous hypotheses of evolution within the group and present a highly supported phylogenetic hypothesis. Atelestidae, Dolichopodidae, Empididae and Hybotidae were supported as monophyletic families, with Atelestidae as sister group to the remaining Empidoidea. Within the family Hybotidae, Bicellariinae stat.n. formed the sister group to the other subfamilies. The family Ragadidae stat.n. is established to include the subfamily Ragadinae and the new subfamily Iteaphilinae subfam.n.; Ragadidae was sister group to the Empididae. Dolichopodidae was found to form a sister group to Ragadidae plus Empididae. Within Empididae, Hemerodromiinae was found to be a nonmonophyletic group. The tribes Hilarini and Hemerodromiini stat. rev. were recovered as sister groups, as were Empidini and Chelipodini stat. rev. The former family Brachystomatidae was found to be nested within Empididae. A revised classification and diagnoses of nondolichopodid families, subfamilies and tribes are provided.

- Heracula discivitta Moore is an uncommon moth species currently recorded from India, Nepal and China. Although this species has traditionally been placed in Lymantriinae, its systematic position in Macroheterocera has been enigmatic due to its unique morphological features. Here we used molecular and morphological data to explore the systematic position of H. discivitta. Our molecular phylogenetic analyses indicate that this species is sister to Pseudobiston pinratanai Inoue, a member of a recently established monotypic family Pseudobistonidae. The examinations of morphological features further show that H. discivitta shares synapomorphies with Pseudobistonidae. Based on the analysis results, we propose a new subfamily of Pseudobistonidae (Heraculinae subfam.n.) to accommodate H. discivitta. The resemblance of the habitus to that of the brahmaeid genus Calliprogonos Mell & Hering is discussed.

Evolutionary history of Euteliidae (Lepidoptera, Noctuoidea)

- We performed a molecular phylogenetic analysis on the family Euteliidae to clarify deep divergences and elucidate evolutionary relationships at the level of the subfamily, tribe, and genus. Our dataset consists of 6.3 kbp of one mitochondrial and seven nuclear DNA loci and was analysed using model-based phylogenetic methods, that is, maximum likelihood and Bayesian inference. Based on the recovered topology, we recognize two subfamilies, Euteliinae and Stictopterinae, and the tribes Stictopterini and Odontini. We identify apomorphic morphological character states for Euteliidae and its component subfamilies and tribes. Several genera (e.g., Targalla, Paectes, Marathyssa, Eutelia) were found polyphyletic and require taxonomic revision. Two new genera (Niklastelia Zahiri & Holloway gen.nov. and Pellinentelia Holloway & Zahiri gen.nov.) are described and a number of taxonomic changes (new combinations and new synonymies) are established. The Neotropical genus Thyriodes, currently included in Euteliidae, is found to be associated with Erebinae (Erebidae). The divergence time estimate for the split between the Euteliidae and Noctuidae is at 53 Ma, and the Euteliidae subfamilies Euteliinae and Stictopterinae are estimated to have diverged at 42 Ma. In Stictopterinae, the tribes Stictopterini and Odontodini split at 31 Ma, while Euteliinae began diversifying at 34 Ma. Malpighiales are inferred to have been the ancestral larval hostplant order for Euteliidae. The ancestors of Stictopterinae also appear to have been Malpighiales feeders, but then diverged to Malvales specialists (Odontodini) and Malpighiales specialists (Stictopterini) hostplants. Larvae of Stictopterini appear to be restricted primarily to Clusiaceae, apart from a few records from Dipterocarpaceae. In Euteliinae, Anacardiaceae are predominant as larval hosts. Thus, all hosts in the family are lactiferous, possibly providing some degree of pre-adaptation for exploiting Dipterocarpaceae.

Tidskriftsartikel (refereegranskat)abstract
- This study presents the first molecular phylogenetic analysis of the Clinocerinae, challenging the traditionally accepted monophyly of this subfamily. DNA was extracted from fresh and museum specimens representing all biogeographical regions. Maximum likelihood (ML) and Bayesian inference (BI) phylogenetic analyses were performed based on sequences from two mitochondrial genes, cytochrome c oxidase subunit I (COI) and cytochrome β, and three nuclear genes, carbomoylphosphate synthase domain of rudimentary, elongation factor-1α and isocitrate dehydrogenase. Through molecular data and morphological examination, our results reveal a division within Clinocerinae, distinguishing ‘typical’ or Clinocerinae (s.s.) from several genera, specifically Afroclinocera Sinclair, Asymphyloptera Collin and Proagomyia Collin, possibly lending support for a reclassification of these genera outside Clinocerinae. Bergenstammia Mik is proposed as a junior synonym of Phaeobalia Mik, syn. n., and the following new combinations are recognized: Phaeobalia albanica (Wagner) comb. n., Phaeobalia aurinae (Pusch & Wagner) comb. n., Phaeobalia carniolica (Horvat) comb. n., Phaeobalia frigida (Vaillant) comb. n., Phaeobalia glacialis (Palaczyk & Słowińska) comb. n., Phaeobalia multiseta (Strobl) comb. n., Phaeobalia nudimana (Vaillant) comb. n., Phaeobalia nudipes (Loew) comb. n., Phaeobalia pulla (Vaillant & Wagner) comb. n., Phaeobalia pyrenaica (Vaillant & Vinçon) comb. n., Phaeobalia slovaca (Wagner) comb. n. and Phaeobalia thomasi (Vaillant & Vinçon) comb. n. Re-evaluation of the genus Roederiodes resulted in the following new combinations: Clinocerella macedonicus (Wagner & Horvat) comb. n. and Clinocerella montenegrinus (Wagner & Horvat) comb. n. The origins of Clinocerinae (s.s.) are traced back to the Holarctic region, Laurasian origin, with a likely complex history of dispersal events into the Southern Hemisphere. Based on current knowledge, the greatest generic and species richness is confined to the Palaearctic Region. These findings provide valuable insights into the evolutionary relationships and distribution patterns of Clinocerinae (s.s.), challenging existing taxonomic classifications and shedding light on their historical biogeography.
