Euura (Gemmura) myrsinifoliae Kopelke, 2001: 218. Described: ♀, ♂, gall, recorded host: Salix myrsinifolia. Holotype, ♀, SMF [examined]. Type locality: Austria, Salzburg, Tauernpass, Obertauern.

Euura (Gemmura) phylicifoliae Kopelke, 2001: 220. Described: ♀, ♂, gall, recorded host: Salix phylicifolia. Holotype, ♀, SMF [examined]. Type locality: Norway, Finnmark, N.- Varanger, Tana Bru. Name preoccupied in Euura by Pontania phylicifoliae Forsius (= E. arcticornis). Syn. nov.

Euura salicisphylicifoliae Kopelke, 2014, in Prous et al. (2014): 53, replacement name for E. phylicifoliae Kopelke.

Notes on types and taxonomy. Morphologically, the nominal species myrsinifoliae and salicisphylicifoliae cannot be separated. Neither were differences found in allozymes, or COI and ITS2 sequences in northern Fennoscandian material of these segregates (Nyman 2002, Leppänen et al. 2014). Accordingly, we treat these taxa as synonyms.

Variability. Female: Body length: 2.4–4.2mm. Clypeus medially black to entirely pale. Supraclypeal area pale to black. Pronotum completely black to narrowly pale-margined. Tegula fuscous to pale yellow. Femora completely yellow to nearly entirely fuscous. Entire underside of abdomen yellow to completely black. Male: 3.5– 3.9. No significant variability in colour pattern. Total number of specimens examined: 11.

Genetic data. COI barcode not distinguishable from those of E. mucronata, and E. nigritarsis.

Similar species. Female; externally not distinguishable from others in the subgroup, except laeta, lanatae, and subgemma, or from testaceipes and venusta. Male not distinguishable from other nominal taxa in the subgroup.

Bionomics. Host plants: Salix myrsinifolia, S. phylicifolia (Kopelke 2001). Biology: Kopelke (2001).

Distribution. Central and North Europe, north to Finnmark in Norway (Kopelke 2001); in Russia probably east at least to the Taymyr Peninsula (E. mucronata on S. phylicifolia: Roininen & Danell 1997).

Occurrence in Sweden: published records; Torne Lappmark (Kopelke 2001).
