- Fourteen Hoplocampa species have been recorded in the West Palaearctic. We provide an illustrated key to these species, together with H. tadshikistanica, which is so far only known from Tadshikistan, but could occur in the West Palaearctic. The suitability of genetic sequencing for identification, particularly of larvae, is discussed. COI barcoding reliably distinguishes all European species which have been sampled (only H. phantoma lacks data), except for H. fulvicornis and H. minuta, which can be identified using nuclear sequences. Distributions in the Fennoscandian countries are outlined, with particular reference to Sweden. Hoplocampa chrysorrhoea is recorded for the first time in Scandinavia, from southern Sweden. Lectotypes are designated for twelve nominal taxa: Allantus ferrugineus Panzer, 1802, Hoplocampa chrysorrhoea var. nigrita Enslin, 1914, H. fabricii W. F. Kirby, 1882, H. oertzeni Konow, 1888, H. pectoralis Thomson, 1871, Hylotoma ferruginea Fabricius, 1804, Tenthredo alpina Zetterstedt, 1838, T. brevis Klug, 1816, T. chrysorrhoea Klug, 1816, T. crataegi Klug, 1816, T. plagiata Klug, 1816, and T. rutilicornis Klug, 1816. Hoplocampa minuta forma dudai Gregor, in Gregor & Bata, 1942 is a new synonym of H. fulvicornis (Panzer, 1801).

Tidskriftsartikel (refereegranskat)abstract
- First records from Sweden of eight sawfly taxa are presented: Arge annulata Konow, 1891(Argidae), Allantus cingillipes (Kontuniemi, 1947), Allantus melanarius (Klug, 1818),Apethymus cereus (Klug, 1818), Dolerus liogaster schneideri Kiaer, 1898, Fenusella hortulana(Klug, 1818), Monophadnus spinolae (Klug, 1816), and Tenthredo mandibularisFabricius, 1804 (Tenthredinidae). The problematic taxonomic status of Arge annulata isdiscussed, and it is recorded for the first time from Germany and Estonia. For Heptamelusdahlbomi (Thomson, 1870) (Heptamelidae): a lectotype is designated for Caenoneuradahlbomi, H. ussuriensis Malaise, 1931 is placed as its junior synonym, Athyrium distentifoliumrecorded as a new host, and additional distribution data are presented, including thefirst records from Austria. A lectotype is designated for Heptamelus magnocularis Malaise,1931, and this species briefly compared with H. dahlbomi.

Recension (refereegranskat)abstract
- The sawfly genus Euura of the tenthredinid subfamily Nematinae, in which species level taxonomy has long been regarded as controversial, is particularly species rich in northern parts of the Holarctic. Among a majority of species with more or less free-living larvae, a sizeable minority belongs to a monophyletic lineage whose larvae complete their whole development in galls. We present illustrated keys to the adults and galls of 66 gall-inducing Euura species that occur, or might occur, in northern Europe. The distribution of these species is briefly reviewed, with an emphasis on the fauna of Sweden, where 55 species are now definitely recorded, two of them for the first time (E. bigallae, E. myrtilloidica). The species-level taxonomy of gall-inducing Euura remains partly problematic. Nominal species described on the basis of experimentally tested or assumed host plant specificity, but which cannot be recognised using morphological or genetic characters, are treated as conspecific with currently indistinguishable segregates ("host-plant races") associated with other Salix species. 20 new synonymies are proposed (valid names in parentheses): Eupontania acutifoliae baltica Vikberg & Zinovjev, 2006 and Pontania acutifoliae daphnoides Zinovjev, 1993 (Euura acutifoliae(Zinovjev, 1985)), Euura boreoalpina Kopelke, 2001 (Euura lanatae Malaise, 1921), Euura cinereae Kopelke, 1996 preoccupied and Euura lapponica Kopelke, 1996 preoccupied (Euura auritae Kopelke 2000), Euura gemmacinereae Kopelke, 2001 and E. nigritarsis Cameron, 1885 (Euura mucronata (Hartig, 1837)), Euura phylicifoliaeKopelke, 2001 (Euura myrsinifoliae Kopelke, 2001), Nematus westermanni Boheman, 1852 nomen oblitum (Euura scotaspis (Förster, 1854) nomen protectum), Nematus acerosus Hartig, 1840 (Euura saliciscinereae (Retzius, 1783)), Nematus alienatusFörster, 1854 and Phyllocolpa rolleri Liston, 2005 (Euura leucapsis (Tischbein, 1846)), Nematus angustus Hartig, 1837 (Euura atra (Jurine, 1807)), Nematus erythropygusFörster, 1854 (Euura leucosticta (Hartig, 1837)), Nematus impunctatus Herrich-Schäffer, 1840 (Euura amerinae (Linnaeus, 1758)), Pontania carinifrons Benson, 1940 and Phyllocolpa plicaglauca Kopelke, 2007 (Euura destricta (MacGillivray, 1923)), Pontania obscura Kopelke, 2005 (Euura bridgmanii (Cameron, 1883)), Pontania viminalis var. lugubris Enslin, 1918 and Eupontania collactanea rosmarinifoliae Vikberg & Zinovjev, 2006 (Euura collactanea (Förster, 1854)). Euura weiffenbachiella nom. nov. is proposed as a replacement name for Euura weiffenbachii Ermolenko, 1988; preoccupied in Euuraby Pteronidea weiffenbachi Lindqvist, 1958 (Euura piliserra (Thomson, 1863)). Lectotypes are designated for the following 9 taxa: Euura insularis Kincaid, 1900, Euura lanatae Malaise, 1921, Euura lappo Malaise, 1921, Euura lappo var. hastatae Malaise, 1921, Nematus acerosus Hartig, 1840, Nematus leptocerus Förster, 1854, Nematus vallisnierii Hartig, 1837, Pontania megacephala Rohwer, 1908, and Pontania piliserra var. mascula Enslin, 1915. Because of secondary homonymy within Euura, the valid name of the Nearctic species E. arctica MacGillivray, 1919 is E. delicatula (MacGillivray, 1919). The Nearctic Euura megacephala is removed from synonymy with the Holarctic E. destricta and treated as a valid species. 34 species names are newly combined with Euura.

- Four Dineura species are now considered to occur in the West Palaearctic, including northern Europe, but D. parcivalvis has not been found in Scandinavia. Dineura pullior Schmidt & Walter, 1995 is treated as a new junior subjective synonym of D. virididorsata (Retzius, 1783). An illustrated key to adults is presented. Lectotypes are designated for seven nominal taxa: Dineura stilata var. virilis Enslin, 1918, Dineura testaceipes var. nigriventris Enslin, 1915, Dineura virididorsata var. dorsalis Enslin, 1915, Nematus posticus Förster, 1854, Nematus xanthocerus Hartig, 1840, Nematus xanthopus Zaddach, 1876, and Tenthredo (Allantus) stilata Klug, 1816. Distributions in the Fennoscandian countries are outlined, with particular reference to Sweden.

- Six valid species of Pseudodineura are now recognised as occurring in the West Palaearctic, and the only described species of the related genus Endophytus. Larvae of all species are leaf-miners in Ranunculaceae. An identification key to adults is provided, followed by species commentaries which include summarised data on taxonomy, larval host plants, and distribution, with particular reference to Sweden. Whereas identification of some specimens using morphological characters may not be possible, each species apparently has a distinct COI barcode sequence. Pseudodineura heringi(Enslin, 1921) is a new junior synonym of P. parvula (Klug, 1816). Pseudodineura mocsaryi Zombori, 1976 and P. scaligera Zombori, 1979 are new junior synonyms of P. clematidisrectae Hering, 1935. Lectotypes are designated for: Dolerus minutus Hartig, 1837, Pelmatopus clematidis Hering, 1932, P. enslini Hering, 1923, P. heringi Enslin, 1921, and P. mentiens var. konowi Enslin, 1921.

The genera of Nematinae (Hymenoptera, Tenthredinidae)
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Recent phylogenetic studies on Nematinae based on DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous DNA sequence datasets based on three genes (CoI, Cytb, and EF-1α), to include a fourth (NaK) and more genera. The analyses largely confirm the previous findings, particularly the existence of two well-supported large clades, Euura and Pristiphora, together comprising more than 75% of the species of Nematinae. Basal relationships within these two clades remain poorly resolved, mirroring the difficulties in delimiting genera based on morphology. In addition, a moderately supported small clade, Nematus, is found. The relationships between the Euura, Pristiphora, and Nematus clades are uncertain. Therefore, to stabilize the nomenclature we treat these clades as genera. This taxonomic treatment results in numerous new combinations of species names. The following synonymies are proposed for the available genus-group names. Synonyms of Euura Newman, 1837: Cryptocampus Hartig, 1837, Euura Agassiz, 1848, Pontania Costa, 1852, syn. n., Epitactus Förster, 1854, syn. n., Amauronematus Konow, 1890, syn. n., Holcocneme Konow, 1890, syn. n., Pachynematus Konow, 1890, syn. n., Holcocnema Schulz, 1906, syn. n., Holcocnemis Konow, 1907, syn. n., Pteronidea Rohwer, 1911, syn. n., Pontopristia Malaise, 1921, syn. n., Brachycoluma Strand, 1929, syn. n., Decanematus Malaise, 1931, syn. n., Pikonema Ross, 1937, syn. n., Phyllocolpa Benson, 1960, syn. n., Eitelius Kontuniemi, 1966, syn. n., Gemmura E.L. Smith, 1968, Eupontania Zinovjev, 1985, syn. n., Larinematus Zhelochovtsev, 1988, syn. n., Polynematus Zhelochovtsev, 1988, syn. n., Bacconematus Zhelochovtsev, 1988, syn. n., Alpinematus Lacourt, 1996, syn. n., Epicenematus Lacourt, 1998, syn. n., Kontuniemiana Lacourt, 1998, syn. n., Lindqvistia Lacourt, 1998, syn. n., Luea Wei and Nie, 1998, syn. n., and Tubpontania Vikberg, 2010, syn. n. Synonyms of Nematus Panzer, 1801: Craesus Leach, 1817, Hypolaepus W.F. Kirby, 1882, and Paranematus Zinovjev, 1978. Synonyms of Pristiphora Latreille, 1810: Diphadnus Hartig, 1837, Lygaeonematus Konow, 1890, Micronematus Konow, 1890, Gymnonychus Marlatt, 1896, Neopareophora MacGillivray, 1908, syn. n., Neotomostethus MacGillivray, 1908, Dineuridea Rohwer, 1912, Sala Ross, 1937, Pristola Ross, 1945, syn. n., Nepionema Benson, 1960, syn. n., Melastola Wong, 1968, syn. n., Sharliphora Wong, 1969, Oligonematus Zhelochovtsev, 1988, Lygaeotus Liston, 1993, Lygaeophora Liston, 1993, and Pristicampus Zinovjev, 1993, syn. n. Varna Ross, 1937, syn. n. is treated as a synonym of Dineura Dahlbom 1835. Stauronematus Benson, 1953 is treated as a separate genus from Pristiphora. Names of 20 species-group taxa are junior secondary homonyms when combined with Euura. Replacement names are proposed for these. To facilitate the identification of Nematinae genera, we provide an illustrated key to the 31 extant genera of world Nematinae.

- Keys to adults and larvae of the genera of West Palaearctic nematine sawflies are presented. Species of some of the smaller genera are keyed, and their taxonomy, distribution, and host plants reviewed, with a geographic focus on north-western Europe, particularly Sweden. Dinematus Lacourt, 2006 is a new junior subjective synonym of Pristiphora Latreille, 1810, resulting in the new combination Pristiphora krausi (Lacourt, 2006) for the type species of Dinematus. Hemichroa monticola Ermolenko, 1960 is a new junior subjective synonym of Hemichroa australis (Serville, 1823). Lectotypes are designated for Tenthredo opaca Fabricius, 1775, Mesoneura opaca var. nigerrima Enslin, 1914, Mesoneura opaca var. obscuriventris Enslin, 1914, Nematus hypogastricus Hartig, 1837, Nematus alnivorus Hartig, 1840, Leptopus rufipes Förster, 1854, Nematus protensus Förster, 1854, and Platycampus luridiventris var. pleuritica Enslin, 1915. A phylogenetic analysis based on four genes (mitochondrial COI and nuclear NaK, POL2, and TPI) supports the current generic classification.

Completing Linnaeus’s inventory of the Swedish insect fauna: only 5,000 species left?
- 2020
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 15:3
-
Tidskriftsartikel (refereegranskat)abstract
- Despite more than 250 years of taxonomic research, we still have only a vague idea about the true size and composition of the faunas and floras of the planet. Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish insect fauna, thought to represent roughly half of the diversity of multicellular life in one of the largest European countries. Our results are based on more than a decade of data from the Swedish Taxonomy Initiative and its massive inventory of the country’s insect fauna, the Swedish Malaise Trap Project The fauna is considered one of the best known in the world, but the initiative has nevertheless revealed a surprising amount of hidden diversity: more than 3,000 new species (301 new to science) have been documented so far. Here, we use three independent methods to analyze the true size and composition of the fauna at the family or subfamily level: (1) assessments by experts who have been working on the most poorly known groups in the fauna; (2) estimates based on the proportion of new species discovered in the Malaise trap inventory; and (3) extrapolations based on species abundance and incidence data from the inventory. For the last method, we develop a new estimator, the combined non-parametric estimator, which we show is less sensitive to poor coverage of the species pool than other popular estimators. The three methods converge on similar estimates of the size and composition of the fauna, suggesting that it comprises around 33,000 species. Of those, 8,600 (26%) were unknown at the start of the inventory and 5,000 (15%) still await discovery. We analyze the taxonomic and ecological composition of the estimated fauna, and show that most of the new species belong to Hymenoptera and Diptera groups that are decomposers or parasitoids. Thus, current knowledge of the Swedish insect fauna is strongly biased taxonomically and ecologically, and we show that similar but even stronger biases have distorted our understanding of the fauna in the past. We analyze latitudinal gradients in the size and composition of known European insect faunas and show that several of the patterns contradict the Swedish data, presumably due to similar knowledge biases. Addressing these biases is critical in understanding insect biomes and the ecosystem services they provide. Our results emphasize the need to broaden the taxonomic scope of current insect monitoring efforts, a task that is all the more urgent as recent studies indicate a possible worldwide decline in insect faunas.

Identification of sawflies and horntails (Hymenoptera, ‘Symphyta’) through DNA barcodes: successes and caveats
- 2017
-
Ingår i: Molecular Ecology Resources. - : Wiley. - 1755-098X .- 1755-0998. ; 17, s. 670-685
-
Tidskriftsartikel (refereegranskat)abstract
- The ‘Symphyta’ is a paraphyletic assemblage at the base of the order Hymenoptera, comprising 14 families and about 8750 species. All have phytophagous larvae, except for the Orussidae, which are parasitoids. This study presents and evaluates the results of DNA barcoding of approximately 5360 specimens of ‘Symphyta’, mainly adults, and 4362 sequences covering 1037 species were deemed of suitable quality for inclusion in the analysis. All extant families are represented, except for the Anaxyelidae. The majority of species and specimens are from Europe, but approximately 38% of the species and 13% of the specimens are of non-European origin. The utility of barcoding for species identification and taxonomy of ‘Symphyta’ is discussed on the basis of examples from each of the included families. A significant level of cryptic species diversity was apparent in many groups. Other attractive applications include the identification of immature stages without the need to rear them, community analyses based on metabarcoding of bulk samples and association of the sexes of adults.
