Abstract: 151 Euura tenuiserra (Lindqvist, 1944) Figs 150, 384 Amauronematus tenuiserra Lindqvist, 1944b: 21–22. Pteronidea semipunctata Lindqvist, 1958: 98. Syn. nov. Diagnosis Mostly black head and thorax, dorsally black and ventrally pale abdomen, and lancet (similar to E. fahraei, but possibly ventrally somewhat more concave) enable identification of the females. Penis valves are similar to those of E. fahraei, but externally the males of E. tenuiserra are much darker (mostly black). Females are superficially similar to those of E. humeralis, but their lancets are clearly different. Type material examined Holotype Amauronematus tenuiserra RUSSIA – Karelia • ♀; Vaaseni [Vaziny]; 60.96° N, 34.01° E; 8 Jun. 1942; V. Karvonen leg.; MZH, http://id.luomus.fi/GL.2772. Holotype Pteronidea semipunctata SWEDEN • ♀; Uppland; R. Malaise leg.; NHRS, NHRS-HEVA000004009. Host plants Salix pentandra. Genetics COI Based on 5 specimens, maximum within-species distance is 3.34% and the nearest neighbour, diverging by a minimum of 6.08%, is Euura bicolor (not known in the West Palaearctic). The two sequenced Finnish specimens are identical (minimum of 3.04% different to the other specimens from Primorsky Kray, Russia), but in one of the specimens two additional secondary COI variants were detected with maximum distance of 1.98% to the primary variant. Nuclear Based on 4 specimens, maximum within-species distance is 1.2% (0.1% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.17%, is Euura bicolor. Distribution and material examined Palaearctic. Specimens studied are from Finland, Russia, and Sweden.
