Euura mucronata

description: Euura mucronata (Hartig, 1837)
Nematus mucronatus Hartig, 1837: 223. Described: ♀, ♂. Lectotype, designated by Kopelke (2001), ♀, ZSM [examined: according to the original description, types in ZMHUB (= "Mus. Klug")]. Type locality: not stated.
Cryptocampus mucronatus: Vollenhoven (1871: but name applied to E. amerinae).
Euura mucronata: Lindqvist (1956). Note: prior to Lindqvist (1956) the name saliceti
was wrongly used for this taxon.
Euura (Gemmura) mucronata: Viitasaari & Vikberg (1985).
Nematus (Euura) mucronatus: Zhelochovtsev (1988).
Euura gallae Newman, 1837: 260. Described: holotype, ♀; OUMNH [examined]. Type locality: Scotland. Nomen oblitum with respect to N. mucronatus (Liston & Prous 2014).
Cryptocampus gemmarum Brischke, 1883b: 207. Described: ♀, ♂, larva, gall, recorded host: Salix aurita. Type material thought to have been destroyed, with most of the rest of Brischke's collection (Blank & Taeger 1998). Type locality: Heubude, Weichselmünde and Brösen [Danzig area, now in Poland]. Note. Authorship of the species name often wrongly attributed to Zaddach or Zaddach & Brischke.
Cryptocampus pictus Brischke, 1883b: 212. Described: holotype, ♂. Type material thought to have been destroyed, with most of the rest of Brischke's collection (Blank & Taeger 1998). Type locality: Königsberg [now Kaliningrad, Russia]. Note. Authorship of the species name often wrongly attributed to Zaddach or Zaddach & Brischke.
Euura nigritarsis Cameron, 1885: 212 –213. Described: ♀, ♂, larva, gall, recorded host: Salix caprea. Syntypes may be in BMNH [not examined]. Type locality: Scotland, Clydesdale. Name preoccupied in Euura by Nematus nigritarsis André, 1880 [a synonym of Euura viminalis]. Syn. nov.
Cryptocampus nigritarsis: Konow (1890).
Euura (Gemmura) nigritarsis: Kopelke (2001).
? Euura insularis Kincaid, 1900: 352. Described: ♀, ♂. Lectotype, ♀, designated below, USNM. Type locality: Alaska, Popof Island. Synonymised by Benson (1962) with Euura mucronata, without any explanation.
Euura (Gemmura) gemmacinereae Kopelke, 2001: 210 –211. Described: ♀, ♂, gall, recorded host: Salix cinerea. Holotype, ♀, SMF [examined]. Type locality: Switzerland, Valais, Grimselpaß, Räterichsbodensee. Syn. nov.
Notes on types and taxonomy. Kopelke (2001) referred to the existence of a holotype of E. nigritarsis, but Cameron's description was based on a syntype series. We detected no significant differences in the morphology, including genitalia, of the nominal species E. mucronata, E. nigritarsis, and E. gemmacinereae. Furthermore, sequencing failed to reveal any genetic differences. Accordingly, these three taxa are treated as synonyms.
Photos of a female syntype of Euura insularis and its labels are available: (http://www.usnmhymtypes.com/ default.asp? Action = Show _ Types & Single _ Type = True &TypeID=6057). The labels include " Co Type No. 5302 U.S. N.M." and " Lectotypus Euura insularis Kincaid 1900 desig. Kopelke 200[?9]". Kopelke apparently did not publish the designation. We hereby designate this specimen as lectotype of E. insularis. Kincaid (1900), in his description of Euura insularis, wrote " Type no. 5301, U. S. National Museum". The published number is wrong: 5301 was correctly assigned by Kincaid (1900) to Pontania peninsularis Kincaid, 1900. It is important to note that the registration numbers used and published by Kincaid [and frequently also by S. A. Rohwer, who worked at the USNM at around the same period] were often applied to syntype series, not individual specimens. Thus, of 10 female and 2 male extant paralectotypes of E. insularis in the USNM, 2 females and 2 males are all labelled " Co Type No. 5302 U.S. N.M.". The other specimens are without such a label.
Variability. Female: Body length: 2.3–4.4mm. Supraclypeal area pale to dark. Pronotum pale-margined to completely black. Tegula yellow to fuscous. Male: 3.2–4.0mm. Extent of pale on inner and outer orbits very variable. Total number of specimens examined: 24.
Genetic data. COI barcode not distinguishable from that of E. myrsinifoliae.
Similar species. Female; externally not distinguishable from others in the subgroup, except laeta, lanatae, and subgemma, or from E. testaceipes and venusta. Male; not distinguishable from other nominal taxa in the subgroup.
Bionomics. Host plants: Salix aurita (Kopelke 2001), Salix caprea (Cameron 1885, Kopelke 2001), Salix cinerea (Kopelke 2003a). Biology: Kopelke (2001), Roininen et al. (1988; as E. mucronata on S. cinerea), Roininen (1991; as E. mucronata on S. cinerea).
Distribution. Central and North Europe north to N. Trøndelag in Norway (Kopelke 2001).
Possibly also North America (Benson 1962). Occurrence in Sweden: probably nearly throughout the country, but most previous records need checking because of confusion with several similar species. Published records: Halland (Andersson 1955, as E. saliceti on S. aurita and S. cinerea), Västergötland (Wahlgren 1961, as E. mucronata on Salix cinerea).
