Euura weiffenbachiella Liston & Heibo & Prous & Vårdal & Nyman & Vikberg 2017, nom. nov.
Description
Euura weiffenbachiella Liston & Vikberg, nom. nov.
Euura weiffenbachii Ermolenko in Zerova, Dyakonchuk & Ermolenko, 1988: 48 –49. Described: ♀, ♂, gall, recorded host: Salix rosmarinifolia. Syntypes, ♀ and ♂, SIZK [not examined]. Type locality: Ukraine, near Kiev, Romanivka District. Euura weiffenbachiella nom. nov. is proposed for E. weiffenbachii Ermolenko, preoccupied in Euura by Pteronidea weiffenbachi Lindqvist, 1958 [E. piliserra (Thomson, 1863)].
Euura (Euura) weiffenbachii Ermolenko: Kopelke (1996).
Variability. Female: Body length: 4.6–5.5mm. Tegula brown to black. Male: 3.6–6.1mm. Female and male: outer orbits and lateral vertex somewhat brown to completely black. Total number of specimens examined: 19.
Genetic data. COI barcode not distinguishable from those of E. myrtilloides, E. salicislapponicae, and E. salicispurpureae.
Similar species. Its robust and usually large body are helpful in recognising this taxon. Females are otherwise most similar to E. myrtilloides: see key for distinguishing characters.
Bionomics. Host plants: Salix repens, S. rosmarinifolia (Kopelke 2003a). Biology: Enslin (1918b; as E. atra on S. repens), Kopelke (1996), Roininen et al. (1993b: as E. atra on S. rosmarinifolia), Weiffenbach (1992). Enslin (1918b) and Weiffenbach (1992) both remarked on two different basic shapes of gall caused by this species: either spindle-shaped, with the shoot remaining straight, or very strongly developed on one side of the shoot, and causing it to bend, like a miniature gall of E. amerinae. We assume that the reason for this is a difference in the way oviposition takes place, and that the different-looking galls are caused by the same species.
Distribution. Central and North Europe (Taeger et al. 2006), east to Yakutia (Popov 2011). Occurrence in Sweden: published records; Skåne (Kullaberg; Benander 1966, as E. atra on Salix repens), Öland (Coulianos & Holmåsen 1991, as E. atra on Salix repens). Material examined: Skåne.
