Euura epilosa

148 Euura epilosa (Lindqvist, 1970) Figs 147–148 Pteronidea epilosa Lindqvist, 1970: 102–103. Diagnosis The colouration and the lancet of E. epilosa are most similar to those of E. nigricornis and E. miliaris, but its antenna is distinctly shorter. Type material examined Holotype Pteronidea epilosa RUSSIA – Irkutskaja oblast • ♀; Irkutsk, Oljhonsk, Popovo; 52.741° N, 106.309° E; 22 May 1967; B.N. Verzhutskii leg.; collected from Spiraea media; MZH, http://id.luomus.fi/GL.5142. Notes Recently discovered in Europe. A single female was collected in Bulgaria in 2022 by E. Heibo close to Spiraea sp. and several larvae on Spiraea media F.Schmidt in Slovakia by A. Lendel (Ladislav Roller, pers com.). Male unknown. The Euura epilosa group includes also E. brachycera (Lindqvist, 1975) (known from Irkutsk oblast and Primorsky Kray, Russia) and possibly Nematus mandshuricus Zhelochovtsev & Zinovjev, 1994 and Euura vastidens (Lindqvist, 1975). Euura epilosa, E. brachycera and N. mandshuricus have been reared from Spiraea, but E. vastidens from Dasiphora fruticosa. Host plants Spiraea media (Verzhutskii 1981). One generation per year. Genetics COI Based on 3 specimens, maximum within-species distance is 1.37% and the nearest neighbour, diverging by a minimum of 6.79%, is Euura brevivalvis. Nuclear Based on 2 specimens, maximum within-species distance is 0.73% (0.05% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 3.45%, is Euura brachycera. Distribution and material examined Palaearctic. Specimens studied are from Bulgaria, Russia, and Slovakia.
