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 phylicifoliae Kopelke, 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 alienatus Förster, 1854 and Phyllocolpa rolleri Liston, 2005 (Euura leucapsis (Tischbein, 1846)), Nematus angustus Hartig, 1837 (Euura atra (Jurine, 1807)), Nematus erythropygus Förster, 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 Euura by 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.

“…Willow–galler–parasitoid communities are distributed across the Northern Hemisphere, and each trophic level in this system contains hundreds of species in geographically variable combinations (Argus ; Kopelke ; Roininen et al . ; Kasparyan & Kopelke ). To obtain a snapshot of a part of this Holarctic ‘trophic quilt’ ( sensu Lewinsohn ), we DNA‐barcoded parasitoid larvae collected from galls induced by seven Pontania species on eight Salix host species in subarctic and arctic–alpine habitats in three locations in northern Fennoscandia.…”

Determinants of parasitoid communities of willow‐galling sawflies: habitat overrides physiology, host plant and space

Studies on the determinants of plant-herbivore and herbivore-parasitoid associations provide important insights into the origin and maintenance of global and local species richness. If parasitoids are specialists on herbivore niches rather than on herbivore taxa, then alternating escape of herbivores into novel niches and delayed resource tracking by parasitoids could fuel diversification at both trophic levels. We used DNA barcoding to identify parasitoids that attack larvae of seven Pontania sawfly species that induce leaf galls on eight willow species growing in subarctic and arctic-alpine habitats in three geographic locations in northern Fennoscandia, and then applied distance- and model-based multivariate analyses and phylogenetic regression methods to evaluate the hierarchical importance of location, phylogeny and different galler niche dimensions on parasitoid host use. We found statistically significant variation in parasitoid communities across geographic locations and willow host species, but the differences were mainly quantitative due to extensive sharing of enemies among gallers within habitat types. By contrast, the divide between habitats defined two qualitatively different network compartments, because many common parasitoids exhibited strong habitat preference. Galler and parasitoid phylogenies did not explain associations, because distantly related arctic-alpine gallers were attacked by a species-poor enemy community dominated by two parasitoid species that most likely have independently tracked the gallers' evolutionary shifts into the novel habitat. Our results indicate that barcode- and phylogeny-based analyses of food webs that span forested vs. tundra or grassland environments could improve our understanding of vertical diversification effects in complex plant-herbivore-parasitoid networks.

“…Due to the great diversity and difficulties in identification of many species in this group, our knowledge of the Norwegian fauna remains insufficient. During the last twenty years, more than 500 species of Ichneumonidae were reported as new to the fauna of Norway (Kopelke 1994, Riedel and Berg 1997, Riedel et al 2000, Horstmann 2004, Riedel et al 2005, Riedel and Hansen 2007, Kasparyan and Kopelke 2009, Hansen et al 2010, Kasparyan and Kopelke 2010, Humala and Reshchikov 2012, Riedel and Hansen 2012, Reshchikov 2013, Riedel and Hansen 2013). Although in total more than 1700 species of Ichneumonidae have been listed for Norway so far, the published checklists from adjacent territories (Koponen et al 1995, Broad 2011) suggest that the Norwegian list is still very incomplete.…”
