Tidskriftsartikel (refereegranskat)abstract
- We describe for the first time the instar III larva of the diving beetle genus Hovahydrus Biström, 1982, based on H. praetextus (Guignot, 1951) and a new species yet to be described (identified here as Hovahydrus sp. near H. minutissimus (Régimbart, 1903)). We include detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi in order to discover useful characters for distinguishing Hovahydrus larvae from those of other known Hyphydrini (Coleoptera: Dytiscidae, Hydroporinae). A provisional parsimony analysis based on larval characteristics of 11 Hyphydrini species in eight genera was conducted using the program TNT. Larval morphology supports a close relationship between Hovahydrus, Hyphydrus Illiger, 1802, and the endemic South Africa genera Andex Sharp, 1882, Coelhydrus Sharp, 1882, Darwinhydrus Sharp, 1882 and Primospes Sharp, 1882.

- We describe the second- and third instar larvae of the diving beetle Rhantaticus congestus (Klug, 1833), including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, terminal abdominal segment and urogomphi in order to discover useful characters for distinguishing Rhantaticus Sharp, 1882 larvae from those of other known Aciliini (Coleoptera: Dytiscidae: Dytiscinae). A parsimony analysis based on 94 larval characteristics of nine Aciliini species in five genera (Acilius Leach, 1817, Graphoderus Dejean, 1833, Rhantaticus, Sandracottus Sharp, 1882, Thermonectus Dejean, 1833) was conducted using the program TNT. Rhantaticus shares with all these genera several larval character states which support its inclusion in the Aciliini. Whereas Rhantaticus larva stands out from other known genera by several unique character states, our parsimony analysis did not recover any clear phylogenetic position of this genus within the Aciliini.

Tidskriftsartikel (refereegranskat)abstract
- Eight new species of Isodiametridae (Acoela) are presented and phylogenetic relationships of the family using 18S and COI sequence data reconstructed. Four species of Baltalimania, two species of Praeaphanostoma and two species of Pseudoposthia are described that all can be distinguished both morphologically and through differences in the DNA sequences as supported by mPTP analysis. The addition of eight new species increases the number of nominal species of Isodiametridae worldwide by 10% and within Sweden by 31%, but also highlights several taxonomic problems. Several species are now confirmed as isodiametrids that are otherwise incongruent with the family's diagnostic characters. Generic keys are presented for Baltalimania and Praeaphanostoma.

Molecular phylogenetics and taxonomy of leaf-toed geckos (Phyllodactylidae: Phyllodactylus) inhabiting the peninsula of Baja California
- 2009
-
Ingår i: Zootaxa. - 1175-5326 .- 1175-5334. ; :2027, s. 28-42
-
Tidskriftsartikel (refereegranskat)abstract
- Herein we assess the phylogenetic relationships and taxonomy of geckos of the genus Phyllodactylus inhabiting the peninsula of Baja California, Mexico using five mitochondrial and two nuclear genes. Phylogenetic analysis using maximum parsimony (MP) and Bayesian inference (BI) recovered three distinct peninsular clades with high statistical support. Sequence divergence estimates between peninsular taxa approached 13%. Two of the species, P. unctus and P. xanti are Cape Region endemics, whereas P. nocticolus is widespread throughout much of the peninsula and extreme southern California. Monophyly of the peninsular taxa was strongly supported. In the MP analysis, P. unctus rooted at the base of the peninsular clade, resolving P. xanti and P. nocticolus as sister taxa. Conversely, BI placed P. nocticolus and P. unctus as sister taxa. These data provide further evidence for a trans-peninsular seaway near the Isthmus of La Paz, severing the Cape Region from the rest of the peninsula. The analysis also supports the validity of P. nocticolus as a distinct species and suggests a single invasion to the peninsula from mainland Mexico, presumably during tectonic activity during the Miocene.

Tidskriftsartikel (refereegranskat)abstract
- The Swedish marine nematologist Carl Allgén (1886–1960) published 185 scientific papers on parasitic, terrestrial, limnic and especially marine nematodes between 1921 and 1960. Among them are also some papers on species of suctorians found mostly on desmodorid nematodes. He described about 70 new genera and over 800 new species and subspecies of nematodes. Allgén left a large collection of nematodes to the Swedish Museum of Natural History in Stockholm and it is now deposited in the invertebrate collection of the Zoology department. The collection comprises about 4500 slides in total, with about 310 slides containing type specimens collected from the Arctic to Antarctica. Allgén’s publications have to a large extent been ignored by scientists working on marine nematodes, likely because of the poor quality of many of his species descriptions. The authors want to remind the scientific community about the existence of Allgén's collection, its availability for study and its importance for nematode taxonomy and systematics. A complete list of Allgén’s publications, a list of all species described by him, and a list of type material available is presented.

-
Tidskriftsartikel (refereegranskat)abstract
- A new species of flat gecko, Afroedura gorongosa sp. nov., is described from Gorongosa National Park, Sofala Province, central Mozambique. The new species is morphologically similar to A. transvaalica and A. loveridgei, from both of which it is genetically distinct (15-17% divergence; 400 bp of 16S rRNA). Morphologically it can be distinguished from both species by having fewer midbody scale rows (97-101) and a higher number of precloacal pores in males (8-13). The type series was collected on the western flanks of Mount Gorongosa (900 and 1100 m a. s. l.) in comparatively cool and moist microclimates, where it is threatened by illegal deforestation. Additional material was collected as low as 212 m a. s. l. on an inselberg near Mount Gorongosa. The new discovery adds to the growing number of endemic montane reptiles discovered in Mozambique in recent years, and highlights the need for a national conservation assessment of the country's herpetofauna and continued protection of the Mount Gorongosa region.

-
Tidskriftsartikel (refereegranskat)abstract
- Dario tigris, new species, is described from mountain streams south of Mogaung, in the Ayeyarwaddy River basin, Myanmar. It differs from congeneric species by its unique colour pattern, which consists of a series of eight straight vertical bars, the first two of which in males are ash-grey and the subsequent six are orange-red in life, combined with a series of small black spots arranged in three to four rows dorsolaterally on the head and nape. It differs further from its close relative Dario hysginon, with which it may occur syntopically, by fewer dorsal-fin spines (modally 14 vs modally 15), and fewer vertebrae (modally 12+12=24 vs modally 12+13= 25). Dario melanogrammus, new species, is another barred Dario from the Chindwin River basin. It differs from all other species of the genus by its zigzagging dark vertical bars; amongst Myanmar species, it can be further distinguished from D. hysginon and D. tigris by more vertebrae (modally 26 vs 25 in D. hysginon, and 24 in D. tigris).

A review of Norwegian streptaster-bearing Astrophorida (Porifera: Demospongiae: Tetractinellida), new records and a new species

Tidskriftsartikel (refereegranskat)abstract
- We report and describe new material of streptaster-bearing Astrophorida sponges collected in Norway: Characella pachastrelloides, Pachastrella nodulosa sp. nov., Poecillastra compressa, Vulcanella cf. aberrans, Thenea abyssorum,Thenea levis, Thenea muricata and Thenea valdiviae. Because many of these species were described in the end of the 19th century their original descriptions are often incomplete. The Norwegian specimens are the basis for a revision of the morphology, taxonomy and distribution of these species. These are the first records of C. pachastrelloides and V. cf. aberrans from the Norwegian coast. Pachastrella nodulosa sp. nov. differs from Pachastrella monilifera by (i) its knobby surface and (ii) the absence of large oxeas, (iii) its amphiasters have on average less actines and are less spiny, finally (iv) microxeas are rare and with a distinct morphology (although there is some doubt concerning their origin). In the present study, Characella tuberosa (from South Africa), Pachastrella abyssi (from the North-West Atlantic) and Thenea schmidti (from the North-East Atlantic) are resurrected. To help their future identifications, all the Norwegian species described were associated with DNA barcodes: a cytochrome c oxidase subunit I (COI) gene partial fragment and/or a 28S ribosomal gene partial fragment (C1–D2 domains). Furthermore, a key to the streptaster-bearing Astrophorida of the North-East Atlantic and the Mediterranean Sea is also given (lithistids not included).

From marine caves to the deep sea, a new look at Caminella (Demospongiae, Geodiidae) in the Atlanto-Mediterranean region

Tidskriftsartikel (refereegranskat)abstract
- Caminella Lendenfeld, 1894 is a poorly known Geodiidae genus with unclear phylogenetic relationships. In order to find new lines of evidence that could shed light on the evolutionary history of Caminella, we decided to revise type material and museum material, as well as examine new material from underwater caves and deep-sea ecosystems. In doing so, we formally show that Isops maculosus Vosmaer, 1894 and Caminella loricata Lendenfeld, 1894 are junior synonyms of Caminella intuta (Topsent, 1892). We discuss different spicule morphological phenotypes in C. intuta, which may be linked to silica availability. We also discovered two new species of deep-sea Caminella: 1) from Cape Verde (Caminella caboverdensis sp. nov.) and 2) from seamounts located south of the Azores archipelago and the North of Spain (Caminella pustula sp. nov.). We reveal that Caminella sterrasters have complex surface microstructures, unique amongst the Geodiidae, where actin tips are linked to each other. Molecular markers (COI, 28S (C1-D2) and 18S) sequenced for some specimens led to new phylogenetic analyses, which continue to suggest a close relationship of Caminella with the Erylinae and Calthropella; these affinities are discussed in light of morphological characters.

Tidskriftsartikel (refereegranskat)abstract
- We describe a new species of Hyalinobatrachium from the Amazonian slopes of the Andes in Peru and Bolivia on the basis of morphological, bioacoustic and genetic characteristics. Hyalinobatrachium carlesvilai sp. nov. can be distinguished from other species of Hyalinobatrachium by the combination of the following characters: (1) truncate snout in dorsal and lateral view; (2) white pericardium; (3) enameled dorsal, tarsal and cloacal folds; (4) hand webbing formula III 2(-) -1(+) IV; (5) iris cream; (6) advertisement call consisting of a single, frequency-modulated note with a pulsed section followed by a tonal section. The new species had been previously identified as Hyalinobatrachium munozorum and H. bergeri. The advertisement call of the new species was previously assigned to H. bergeri. Here we describe the previously unknown call of Hyalinobatrachium bergeri. Additionally, we study the taxonomic status of H. lemur and H. pellucidum and place the former as synonym of the later. We extend the distribution of H. pellucidum to Departamento Cusco in southern Peru.

The arctic and alpine bumblebees of the subgenus Alpinobombus revised from integrative assessment of species' gene coalescents and morphology (Hymenoptera, Apidae, Bombus)
- 2019
-
Ingår i: Zootaxa. - : Magnolia Press. - 1175-5326 .- 1175-5334. ; 4625, s. 1-68
-
Tidskriftsartikel (refereegranskat)abstract
- The bumblebees of the subgenus Alpinobombus of the genus Bombus are unusual among bees for specialising in many of the most northerly vegetated arctic habitats on Earth. Most named taxa in this group (37 available names from a total of 67 names) were described originally from differences in the colour patterns of the hair. Previous revisions have shown unusually little agreement, recognising a range of 6.9 species, in part because of pronounced intraspecific variation in both skeletal morphology and in the colour patterns of the hair. Here we examine variation among 4622 specimens from throughout the group's global range. Bayesian inference of the gene tree for the fast evolving mitochondrial COI gene combined with Poisson-tree-process analysis of this tree shows support for 10 gene lineages as candidates for being putative species lineages. Integrative assessment shows that the interpretation of these results is not straightforward. Evidence from the fast evolving mitochondrial 16S ribosomal RNA gene supports two of the COI gene alleles (from the samples B. kluanensis s. str. and 'unnamed2') as being associated with just one 16S allele. Double COI bands on the PCR gels for these individuals and double peaks on sequence traces (in one case with both COI alleles sequenced from one individual) identifies this as a likely case of COI paralogy that has resulted in mitochondrial heteroplasmy. Evidence from morphology also supports only the remaining nine lineages as separate. Evidence from extracts of cephalic labial gland secretions (CLGS, with components believed to function as sex pheromones) reported by others shows small diagnostic differences between all of the candidate species examined (although B. kluanensis s. l. was not examined) and shows larger differences between all of the species pairs that we find are likely to have co-occurred at least in the past, revealing a likely limitation to the CLGS approach in cases of recent and continuously allopatric species. Consequently we infer nine species in the subgenus Alpinobombus (so that B. kluanensis s. str. and 'unnamed2' are interpreted as conspecific, as B. kluanensis s. l.). We provide distribution maps and identification keys for the nine species. The morphology of the male of B. kluanensis is described for the first time, including a unique, unusually dense pad of short hair on the mandible that may have a function involving CLGS in mate-searching behaviour. In seeking to identify the valid names for these species, seven new lectotypes are designated and support is provided for synonymizing 10 names as proposed in a recent summary table of names. The prevailing usage of Bombus balteatus Dahlbom is maintained as valid by proposing Bombus nivalis Dahlbom and Bombus tricolor Dahlbom as nomina oblita and by proposing Bombus balteatus Dahlbom as a nomen protectum. The prevailing usage of Bombus hyperboreus Schonherr is maintained as valid by supporting Apis arctica Quensel as a nomen oblitum and by supporting Bombus hyperboreus Schonherr as a nomen protectum. We then use sequence data from COI and 16S together with nuclear PEPCK and opsin genes to estimate dated phylogenetic relationships among the nine species, allowing for incongruent gene trees with *BEAST. If crown-group divergence within the subgenus Alpinobombus coincided with the global climate cooling and with the growth of the northern ice sheets at the end of the Miocene at ca 7.2 Ma, then divergences between each of the three pairs of sister species are likely to have coincided with fluctuations in vegetated land connections across the Bering Strait after ca 2.5 Ma.

A case of allopatric speciation in the Central System (Iberian Peninsula): Leistus elpis sp. nov., a sibling species of Leistus constrictus (Coleoptera, Carabidae)
- 2021

Tidskriftsartikel (refereegranskat)abstract
- The aim of this work was to demonstrate that the Leistus (Leistus) constrictus Schaufuss 1862 populations from Sierra de Ayllón belong to a new sibling species of the true L. (L.) constrictus from Sierra de Guadarrama. We describe Leistus (Leistus) elpis sp. nov. The species were separated by the study of external morphology of qualitative characters, especially male genitalia, and quantitative characters (morphometric analysis). In L. (L.) constrictus the apical lamina of the aedeagus appears to be a long gutter flanked by lateral ridges with an open truncation in its anterior part; in L. (L.) elpis sp. nov. the apical lamina is completely ridged, even in the anterior part, forming a kind of labial thickening, enclosing the median lobe, and giving the apex a clearly closed and pointed outline. It is not possible, or very difficult, to distinguish between females of L. (L.) constrictus and females of L. (L.) elpis sp. nov., based on their external anatomy as they are practically identical. The female genitalia do not offer taxonomic information for discriminating between the species using the genital armour or the structure of the spermathecal complex. However, subtle differences were found through morphometric analysis, as well as for males of both species. Field surveys suggest that the pass Puerto de Somosierra is the geographical barrier that has led to this allopatric speciation.

Sex attractant, distribution and DNA barcodes for the Afrotropical leaf-mining moth Phyllonorycter melanosparta (Lepidoptera: Gracillariidae))
- 2009

Tidskriftsartikel (refereegranskat)abstract
- The sex attractant for Phyllonorycter melanosparta (Meyrick, 1912) has been determined as (10E)-dodec-10-en-1-yl acetate and (10E)-dodec-10-en-1-ol combined in a ratio 10:1. The distribution of this species in Eastern Africa is updated and its presence in Kenya is recorded for the first time. We discuss the taxonomic status of P. melanosparta with reference to three character sets: semiochemicals, morphological and molecular characters (DNA barcodes). This combination of characters is also proposed as a new approach to study the diversity and phylogeny of Phyllonorycter in the Afrotropical region.

Molecular characterization of haemosporidian parasites (Haemosporida) in yellow wagtail (Motacilla flava), with description of in vitro ookinetes of Haemoproteus motacillae
- 2013

Tidskriftsartikel (refereegranskat)abstract
- In studies of haemosporidian systematics and taxonomy, a combination of microscopic examination and molecular identification has been recommended. The yellow wagtail (Motacilla flava) is a frequently used species in studies of host-parasite interactions; blood parasites of this bird have been well studied using microscopic examination of blood films, but data on molecular characterization of the parasites are scattered. Here we present the first study linking several haemosporidian cyt b sequences with their morphospecies parasitizing the yellow wagtail, combining light microscopy and nested PCR methods. The lineage hYWT1 of Haemoproteus motacillae was the most prevalent parasite; it was recorded in 38% of the birds. The latter lineage and the lineages hYWT2, hYWT3, hYWT5 and hYWT6 form a well-supported clade on the phylogenetic tree and likely represent intraspecific genetic variation of H. motacillae, with genetic divergence of 0.3-1.5 % among these lineages. Microscopic examination of smears prepared during an in vitro experiment, which was designed for observation of developing ookinetes, showed that H. motacillae ookinetes were present 5 hours after exposure of blood to air at 18-20 degrees C. Ookinetes of this parasite belong to a group of large Haemoproteus spp. ookinetes (19.9 mu m in length on average). Illustrations of the parasites are given. Two of reported Plasmodium lineages, pCOLL1 and pYWT4 are phylogenetically closely related to the widespread host generalist parasites Plasmodium relictum (cyt b lineages pSGS1, pGRW4 and pGRW11), but it was not possible to establish this morphologically. This study contributes to the molecular identification of avian haemosporidian parasites and provides information on morphology of H. motacillae ookinetes, which is additional information assisting the microscopic identification of this species.

Molecular and acoustic evidence support the species status of Anthus rubescens rubescens and Anthus [rubescens] japonicus (Passeriformes : Motacillidae)

- The Buff-bellied Pipit Anthus rubescens comprises two allopatric subspecies groups: A. r. rubescens and A. r. alticola in North America and A. [r.]japonicus in north-east Asia. Despite their great morphological resemblance in breeding plumage, most individuals can be assigned to one or the other subspecies group in non-breeding plumage. Allopatric distributions, morphological differentiation and previously reported molecular divergence suggested the need for additional taxonomic study to assess the rank of these two populations. To resolve the taxonomy of the Buff-bellied Pipit species complex we analysed i) two mitochondrial DNA (mtDNA) loci and ii) nine bioacoustic parameters across 69 sound recordings (338 flight calls) recovered from public databases using principal component analysis and Euclidean distance measures. By comparing our mtDNA and call divergence measures with similar values measured between long-recognised species pairs of the genus, we show that the level of mitochondrial and acoustic divergence between the two Buff-bellied Pipit subspecies groups is typical of species-level divergence in the genus Anthus. Therefore, we recommend splitting the Buff-bellied Pipit species complex into two species: Anthus rubescens (American Pipit) and Anthus japonicus (Siberian Pipit). Our results also suggest that the Water Pipit A. spinoletta deserves taxonomic reassessment as its lineages are highly divergent in acoustics and mtDNA, while mtDNA relationships suggest paraphyly relative to the Rock Pipit A. petrosus. Our work highlights the crucial importance of integrative approaches in taxonomy and the usefulness of bioacoustics in studying cryptic diversity.

Tidskriftsartikel (refereegranskat)abstract
- North Sweden (‘Norrland’ in Swedish) covers 243 000 km2 and lies mainly in the boreal biome. The herpetofauna comprises five amphibian and four reptile species: Lissotriton vulgaris, Triturus cristatus, Bufo bufo, Rana temporaria, Rana arvalis, Zootoca vivipara, Anguis fragilis, Natrix natrix, and Vipera berus. Successful conservation and management of amphibians and reptiles depend on accurate information about distribution, habitat affinities, and abundance. Such knowledge is also essential as a benchmark to assess changes in distribution and abundance that may come about as a result of climate change and human habitat alteration. This paper aims to present accurate distribution maps, describe habitat affinities, and provide abundance estimates for the herpetofauna of North Sweden for the period 1970–2022. Distribution data are presented by traditional faunistic provinces, as well as by biotic regions and alpine life zones. Separate sections address post-glacial colonization and a herpetological perspectiveon anthropogenic changes in relation to species´ present status. Bufo bufo, Rana temporaria, Rana arvalis, Zootoca vivipara, and Vipera berus are widely distributed throughout the boreal sub-regions. Rana temporaria, Zootoca vivipara, and Vipera berus also extend into the alpine region. Triturus cristatus, Anguis fragilis, and Natrix natrix occur mainly in the coastal parts of the Southern Boreal region. There are no signs of recent changes in distribution range, but Lissotriton vulgaris, Triturus cristatus, and Rana arvalis have been largely overlooked in the past and have a much wider occurrence than previously recognized. Most species are found in habitats usually not described in all-European field guides. Nearly all anurans hibernate in water. Abundance estimates suggest that some species are more common in the boreal than thought, supporting the notion that a large share of their total European population occurs there. Although local extinctions and declines are known, there are no signs of widespread population decline for any species during the study period.

- Published records on the Ophiuroidea fauna of the Persian Gulf and Gulf of Oman are scattered in difficult to access journals and books. This study presents a compilation of all published records, complemented with data from new samples. Distribution, habitat and depth in the study area, as well as known Indian Ocean distributions, are included. The taxonomic status of all species was evaluated, critical comments were added as applicable, and several previous records were reassigned to other species. Ophiocoma erinaceus was removed from the fauna of the Persian Gulf and Gulf of Oman, because the only published record was instead Ophiocoma schoenleinii. Previous studies assumed that 46 species of brittle star were known from the study area, but only 38 species were confirmed by this re-assessment, including two new records (Ophiothrix (Ophiothrix) foveolata and Ophiocomella sexradia). Diagnostic features are supplied for difficult to distinguish species. Five species (Macrophiothrix elongata, Amphiura fasciata, Amphiura (Ophiopeltis) hexactis, Amphioplus echinulatus, and Amphioplus seminudus) are so far worldwide known only from the Persian Gulf area. A hexamerous, fissiparous species of Ophiothela that does not concur with any known species was found and may represent a new species. All newly collected species are illustrated with photographs.

Tidskriftsartikel (refereegranskat)abstract
- The satyrine Euptychia pronophila Butler (Nymphalidae) was described in 1867 in the “catch-all” genus Euptychia, but was recently treated as incertae sedis. A DNA-based cladistic analysis confirms that it belongs to the Euptychiina, as sister to Forsterinaria and closely related to Taygetis, Posttaygetis, Parataygetis, Pseudodebis, and Harjesia. Although immature morphology also suggests that this species is closely related to Forsterinaria, none of the adult morphological synapomorphies for the genera in the aforementioned clade occur in E. pronophila, a highly autapomorphic species. Because we were unable to place it with confidence in an established genus, the monotypic satyrine genus Guaianaza Freitas & Peña New Genus is described, with Euptychia pronophila Butler as the type species

- The fauna occurring in waters off South-West Africa is of a remarkable composition and highly diverse due to local waterbodies, flow conditions and abiotic factors. These parameters predominate as a result of the cooperation of a major coastalupwelling system (the Benguela Current Large Marine Ecosystem), the Benguela Current flowing northwards, thesouthward directed Angola Current and the Angola–Benguela Frontal Zone formed in the transition zone of both watercurrents. This area has been insufficiently explored within the last decades and major gaps in biodiversity knowledge existto date. Two expeditions were conducted in 2004/2008, which collected benthic fauna samples. This is a list of brittle starsfound and a comprehensive research study relating to Ophiuroidea in waters off Angola and Namibia. 17 species could beidentified at depths from the littoral zone down to 125 m. The known depth and geographical distributions were extended for several species. Short diagnoses and ecological data are included.

Back in time to unlock the future: tracing the type-specimens of Corallus hortulana (Linnaeus, 1758) (Serpentes: Boidae), with designation of a lectotype for the Amazon tree boa
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Corallus hortulana presents a large array of tones and color pattern variability throughout its distribution (= polychromatism), which trigged the description of several taxa now considered to be primary synonyms. Linnaeus described two of these (Boa enydris and Boa hortulana) on the same page of the 10th Edition of the Systema Naturae. However, both names had been widely used in literature almost in an optional way, until their formal synonymization more than two centuries after the original description. Additionally, the type specimen of Boa hortulana was reported as missing since the late 19th century. These two factors may have enabled the unjustified switched association of types, which was perpetuated in the literature to the present day. Our main goals here were to trace the correct type specimens for each species through a literature review and specimen examination, and to amend the switched association of type material. We found two specimens in the collection of the Uppsala University that are unmistakably associated with Boa hortulana. Herein we designate one of them as its lectotype in order to promote nomenclatural stability considering its huge phenotypic variability and the future possibility of eventually splitting the species.

Phylogenetic systematics of Glassfrogs (Amphibia: Centrolenidae) and their sister taxon Allophryne ruthveni
- 2009
-
Ingår i: Zootaxa. - 1175-5326 .- 1175-5334. ; :2100, s. 1-97
-
Forskningsöversikt (refereegranskat)abstract
- Based on a molecular phylogeny, a new phylogenetic taxonomy that is compatible with both the International Code of Zoological Nomenclature (ICZN) and the PhyloCode is proposed for Glassfrogs and their sister taxon, Allophryne ruthveni. The arrangement presented herein emphasizes the recognition of clades having (i) significant statistical support and congruence among phylogenetic estimation methods (i.e., parsimony, maximum likelihood, and Bayesian inference criteria), (ii) congruence among genetic markers, and (iii) morphological and/or behavioral distinctiveness. Also, when previously recognized groups are recovered as monophyletic or nearly monophyletic, we propose taxa that minimize the number of name changes required to make these groups monophyletic, preserving the names and contents of previous classifications (i.e., nomenclatural stability). The evolutionary proximity of Centrolenidae and Allophrynidae is recognized by combining these families into an unraked taxon, Allocentroleniae-a proposal that maintains the traditional names and species contents of Centrolenidae and Allophrynidae. We arrange centrolenid diversity in two subfamilies: Centroleninae and Hyalinobatrachinae. Within Centroleninae, the diagnosis and species content of the genera Centrolene, Cochranella, and Nymphargus are modified; Teratohyla is resurrected and modified, and Chimerella, Espadarana, Rulyrana, Sachatamia, and Vitreorana are proposed as new genera. The other subfamily, Hyalinobatrachinae, contains the new genus Celsiella and a modified Hyalinobatrachium that fully corresponds to the former fleischmanni Group. Additionally, the genus Ikakogi is described. Ikakogi could not be assigned with confidence to either subfamily and it is placed as incertae sedis in Centrolenidae. The data at hand suggest that Ikakogi tayrona is a lineage as old as the subfamilies Hyalinobatrachinae and Centroleninae. The revised taxonomy differs markedly from previous arrangements, which were based on phenetics and few morphological characters. Most of the genera defined herein are confined to distinct biogeographic regions, highlighting the importance of geography in the speciation of Glassfrogs. The principal limitation of this proposal is that it is based on an incomplete sampling of taxa (54% of the recognized Glassfrogs). Although diagnoses are based on phenotypic traits, there are several cases (16% of all species) in which the allocation of species is ambiguous because of morphological homoplasy and the lack of molecular data. Finally, in an attempt to facilitate species identification, comparison, and generic placement, we provide photographs for most (similar to 96%) of the recognized centrolenid species.

- We assess the taxonomic status of Hyalinobatrachium petersi and Cochranella ametarsia based on the examination oftype material and recently collected specimens. We conclude that the material assigned to them is morphologically undistinguishablefrom two previously described species (Cochranella pulverata and Cochranella oyampiensis, respectively) and, therefore, are junior synonyms.

- Apostolepis gaboi was described based only on the holotype found in the Queimadas, state of Bahia, northeastern Brazil. Since its original description, no additional specimens were reported in literature and the species was considered to be rare and poorly known. Here, we provide a detailed description for the species based on the examination of the holotype and 34 additional specimens from the type locality and adjacent areas. Additional information is also provided on intraspecific color variation and hemipenial morphology.

Tardigrades of Sweden : an updated check-list

- Tardigrades occur worldwide and in a variety of ecosystems and habitats representing an important component of the micrometazoan biodiversity. Several studies documenting the occurrence of tardigrades in Sweden have been published since the first reports in early 1900, but no comprehensive summary of these studies have been published. We compiled the available information on recorded tardigrades from Sweden, using material from published studies and museum and university collections. In total, our review document 101 species of tardigrades that have been recorded from Sweden (an updated checklist of tardigrades from Sweden will be available online), of which 14 species are new records for the country. The highest number of species was recorded in the northernmost province of Lappland and the more southern provinces of Uppland and Skåne, while much lower species numbers are reported from the middle part of Sweden. This pattern probably represents biased sampling activities of biologists rather than real differences in biodiversity of tardigrades. In view of the few studies that have been made on tardigrade biodiversity in Sweden, the relatively high number of tardigrade species recorded, representing almost a tenth of the species recorded worldwide, indicates that many more species remain to be found. In this respect, more studies of the marine ecosystems along the Swedish west coast and the long Baltic Sea coastline would be of particular interest.

Taxonomy and biostratigraphy of Ordovician brachiopods from northeastern Ny Friesland, Spitsbergen

Tidskriftsartikel (refereegranskat)abstract
- We describe Early and Middle Ordovician brachiopod faunas from northeastern Spitsbergen and discuss their biostratigraphical and palaeoecological implications. We recognise 60 species and 41 genera representing both linguliform and rhynchonelliform brachiopods. These include one new genus, the obolid Lenticulella with the type species Lenticulella amphora (Krause & Rowell, 1975), and 23 new species: Ectenoglossa? oviforma, Elliptoglossa vulgaris, Rosobolus? elongatus, Broeggeria obscura, Mirilingula? svalbardensis, Schizotreta marginalis, Conotreta convexa, Cyrtonotreta profilbekkiensis, Cyrtonotreta spinosa, Eurytreta subtriangularis, Hisingerella maniformis, Semitreta basisslettaensis, Semitreta pustulosa, Semitreta spitsbergensis, Numericoma? proclina, Eoconulus subquadratus, Dictyonites mugilis, Pelonomia sulcata, Leptella (Leptella) inequicostellata, Protosken-idioides promontorium, Anomalorthis rossi, Nothorthis subpyramidalis and Phragmorthis noda. The Ordovician succession contains both intertidal and deep-sea deposits with brachiopod faunas from nearly the whole range of environments. The Tremadocian is represented by a succession of low-diversity, rhynchonelliform-dominated assemblages occupying shallow-marine environments. With the abrupt and large-scale drowning during the Floian, these faunas were replaced by a sparse slope fauna of micromorphic linguliforms. The outer shelf environments established in the latest Floian were occupied by a highly diverse brachiopod fauna dominated by micromorphic linguliform taxa. As the environment shifted toward the mid-shelf during the Darriwilian, however, the composition of the fauna changed to an Orthidiella-dominated assemblage of mostly rhynchonelliform taxa. The very late occurrence of the Orthidiella assemblage suggests that the Dapingian Orthidiella Zone found in America is probably diachronic. Although it includes many endemic species, the Middle Ordovician fauna shows a strong resemblance to the brachiopod fauna of Nevada. This study is based on approximately 16 500 brachiopod specimens obtained from both crack-out samples and acetic-acid-treated bulk samples.

- The genus Eulophinusia Girault (Hymenoptera: Eulophidae), previously known from Australia and India, is newly recorded from the Americas (Canada, Costa Rica, Dominican Republic). The morphological diagnosis of the genus is enhanced through the discovery of an unnoticed and unique feature - an intricate jigsaw-like microsculptural pattern on the mesoscutellum. The new species described here, Eulophinusia andreamezae Hansson, is a hyperparasitoid. The majority of the Costa Rican specimens of this species were reared from pupae of Hypomicrogaster largus Valerio (Braconidae: Microgastrinae) that had parasitized a caterpillar of Anadasmus Janzen11 (Lepidoptera: Depressariidae) feeding on Ocotea insularis (Lauraceae).

- The European species of Diglyphus Walker are reviewed. Fifteen species are included. One of these, D. clematidis sp. n., is described as new, and one, D. anadolucus Doganlar, is recorded as new to Europe. Several of the species have their geographical distribution increased as many new country records are introduced. New host records and compilation of host records from the literature are presented in tables. To facilitate the identification of the species a key and numerous illustrations are included. The identity of one of the species described from Europe, D. phytomyzae Ruschka, is unclear. It has not been possible to locate the type material of this species and the original description is not detailed enough to make an unambiguous interpretation possible. Two species, D. scapus Yefremova from Iran and D. sensilis Yefremova from Turkey, are discussed as they occur in the vicinity of Europe.

- The European species of Foersterella Dalla Torre 1897 (Hymenoptera: Tetracampidae) are treated, including two previ-ously described species, F. erdoesi Bouček and F. reptans (Nees), and two new species, F. angusticornis sp. nov. and F. fuscicornis sp. nov. Morphological concepts of the species are based mainly on characters in the male antenna, which fe-males lack, and with the exception of F. erdoesi females are currently not possible to identify to species. A key for the identification of species is included, as well as illustrations to facilitate the identification.

- Two new species of Sporrongia Gumovsky (Eulophidae: Entedoninae), S. marginata sp. nov. from Costa Rica and Mexico, and S. niveicornis sp. nov. from Peru, are described and compared to the single previously known species, S. tobagoiensis Gumovsky. Sporrongia marginata has been reared from galls on the legume Andira inermis (Leguminosae). This is the first biological record for the genus and an indirect indication of possible gall induction by S. marginata.

- Two new Eulophinae genera, Elasmarion and Celesterion, are described based on material from sweep-net and malaise trap samples mainly from Costa Rica. The new genera are each represented by a single species, both described here, E. longipes and C. reticulatum spp. nov. The material for both groups is abundant and strongly female biased, 119 females and two males in Elasmarion, and 63 females and two males in Celesterion. Elasmarion is similar to the Old World genus Eulophomorpha Dodd, and a table with distinguishing characters is included, it also has some morphological features similar to the genus Elasmus Westwood. Celesterion does not show close morphological similarity to any genus in the Eulophinae. The biology is unknown for both species.

- Leptolaimus timmi Vitiello, 1971 is redescribed from bottom sediments collected in the Skagerrak off the west coast of Sweden. New morphological data necessitate the transfer of this species to the genus Rhadinema Cobb, 1920. The main diagnostic characters of Rhadinema timmi (Vitiello, 1971) comb. n. include: 1.3–1.8 mm long body; rounded labial region weakly offset from body contour; cephalic setae 2–4 μm long; amphid located 12–19 μm from anterior end; first body pore located 22–30 μm from anterior end; lateral field absent; stoma tubular: cheilostom with six weakly cuticularised longitudinal rugae, gymnostom with sclerotized bar-shaped rhabdia, stegostom long, tubular; female without supple- ments, vagina without pars refringens, vulva midventral; male with 10–11 tubular and without alveolar supplements; spic- ules arcuate and 21–30 μm long.
