DNA sequences accumulating in the International Nucleotide Sequence Databases (INSD) form a rich source of information for taxonomic and ecological meta-analyses. However, these databases include many erroneous entries, data itself is poorly annotated with metadata, making it difficult to target extract entries interest any degree precision. Here we describe web-based workbench PlutoF, which designed bridge gap between needs contemporary research biology existing software resources...
The sawfly genus Euura of the tenthredinid subfamily Nematinae, in which species level taxonomy has long been regarded as controversial, is particularly rich northern parts Holarctic. Among a majority with more or less free-living larvae, sizeable minority belongs to monophyletic lineage whose larvae complete their whole development galls. We present illustrated keys adults and galls 66 gall-inducing that occur, might Europe. distribution these briefly reviewed, an emphasis on fauna Sweden,...
Of the two known Eupareophora species, more is about larva and bionomics of Nearctic E. parca, than rarely recorded West Palaearctic exarmata.
Six valid species of Pseudodineura are now recognised as occurring in the West Palaearctic, and only described related genus Endophytus. Larvae all leaf-miners Ranunculaceae. An identification key to adults is provided, followed by commentaries which include summarised data on taxonomy, larval host plants, distribution, with particular reference Sweden. Whereas some specimens using morphological characters may not be possible, each apparently has a distinct COI barcode sequence. heringi...
Four Dineura species are now considered to occur in the West Palaearctic, including northern Europe, but D. parcivalvis has not been found Scandinavia. pullior Schmidt & Walter, 1995 is treated as a new junior subjective synonym of virididorsata (Retzius, 1783). An illustrated key adults presented. Lectotypes designated for seven nominal taxa: stilata var. virilis Enslin, 1918, testaceipes nigriventris 1915, dorsalis Nematus posticus Förster, 1854, xanthocerus Hartig, 1840, xanthopus...
Phylogenomic approaches have recently helped elucidate various insect relationships, but large-scale comprehensive analyses on relationships within sawflies and woodwasps are still lacking. Here, we infer the long-term biogeographic history of these hymenopteran groups using a large dataset 354 UCE loci collected from 385 species that represent all major lineages. Early Hymenoptera started diversifying during Triassic ∼249 Ma spread over ancient supercontinent Pangaea. We recovered Xyeloidea...
Abstract The ‘Symphyta’ is a paraphyletic assemblage at the base of order Hymenoptera, comprising 14 families and about 8750 species. All have phytophagous larvae, except for Orussidae, which are parasitoids. This study presents evaluates results DNA barcoding approximately 5360 specimens ‘Symphyta’, mainly adults, 4362 sequences covering 1037 species were deemed suitable quality inclusion in analysis. extant represented, Anaxyelidae. majority from Europe, but 38% 13% non‐European origin....
Abstract Molecular identification of micro- and macroorganisms based on nuclear markers has revolutionized our understanding their taxonomy, phylogeny ecology. Today, research the diversity eukaryotes in global ecosystems heavily relies ribosomal RNA (rRNA) markers. Here, we present community-curated reference database EUKARYOME for 18S rRNA, internal transcribed spacer (ITS) 28S rRNA all eukaryotes, including metazoans (animals), protists, fungi plants. It is particularly useful arbuscular...
New data on the distribution of 11 Symphyta species phyllophagous birch trees ( Betula L.) are presented. Dineura virididorsata (Retzius, 1783), Heterarthrus nemoratus (Fallén, 1808), Nematinus caledonicus (Cameron, 1882), Pamphilius varius (Audinet-Serville, 1823), and Pristiphora alpestris (Konow, 1903) reported from Slovakia for first time.

Excluding 102 species of the previously revised West Palaearctic groups Euura Newman, 1837 (gall-making groups, 84 species; amentorum group, 8 bergmanni and oligospila 2 species), we treat here remaining 164 genus. 145 new synonymies are proposed (one in Platycampus, one Nematus, two Pristiphora, rest Euura: see Table 4 for details). 153 lectotypes designated (see 4). Four nominal reinstated (valid name square brackets): Pteronidea fuscarima Benson, 1933 [E. (Benson, 1933) comb. nov.], P....
Recent phylogenetic studies on Nematinae based DNA sequences have shown extensive incongruencies with current nomenclature of genus-group taxa. Here, we expand previous sequence datasets three genes (CoI, Cytb, and EF-1α), to include a fourth (NaK) more genera. The analyses largely confirm the findings, particularly existence two well-supported large clades, Euura Pristiphora, together comprising than 75% species Nematinae. Basal relationships within these clades remain poorly resolved,...

The Pristiphora ruficornis group, defined here based on the structure of penis valve and genetic data, includes morphologically genetically highly similar species that remain taxonomically challenging. Study most relevant type material, examination female saws male genitalia, some rearing experiments, data enabled us to solve taxonomic problems involving northern European taxa. As a result, 17 are recognised in Europe. following synonymies proposed: aterrima Lindqvist, 1977, syn. n. is...
The Empria longicornis species group (Hymenoptera, Tenthredinidae) is revised. japonica Heidemaa & Prous, sp. nov. described from Japan. lectotypes of gussakovskii Dovnar-Zapolskij, 1929, E. konowi Poecilosoma Thomson, 1871, P. mongolica Konow, 1895, and tridens 1896 are designated. 1929 (syn. nov.) synonymized with (Konow, 1896), waldstaetterense Liston, 1980 alector Benson, 1938. alpina 1938 minuta Lindqvist, 1968, earlier misidentified as gussakovskii, treated valid species.

Forty-two sawfly species are now known from Crete, including twelve here recorded for the first time, and excluding earlier published records of Allantus didymus (Klug, 1818) based on misidentifications. nigrolinearis (Zirngiebl, 1937) is treated as a distinct within laticinctus-didymus group. Aneugmenus oertzeni (Konow, 1887) allied to Sardo-Corsican A. bibolinii Zombori, 1979 belongs Hartig, 1837 s. str., not Atoposelandria Enslin, 1913. Pristiphora nievesi Haris, 2002 new synonym P....

Except for one record, no species of horsehair worms (Nematomorpha) have been recorded from Estonia.We report here the finding 35 specimens, 14 them determined as Gordionus violaceus (Baird, 1853), a widespread European species.Three new are described.These Gordius balticus sp.nov.with an angled postcloacal crescent and fine stout bristles on cuticular surface, spiridonovi row extending posterior tips onto tail lobes, terminosetosus longer lobes.Additionally, some specimens genus L. with...
Abstract In several sawfly taxa strong mitonuclear discordance has been observed, with nuclear genes supporting species assignments based on morphology, whereas the barcode region of mitochondrial COI gene suggesting different relationships. As previous studies were only few genes, causes and degree remain ambiguous. Here, we obtain genomic-scale ddRAD data together Sanger sequencing two to three protein coding investigate limits in closely related groups within genus Empria . found...
