Abstract: 238 Euura longicauda (Hellén, 1948) Figs 256, 495 Nematus (Amauronematus) longicauda Hellén, 1948: 113–114. Lectotype designated below. Diagnosis Females are most similar in colouration to E. munda, but with distinctly more pronounced serrulae. Serrulae are similar to E. longiserra, although apparently narrower, but E. longicauda is dorsally also darker (mostly black, E. longiserra nearly completely or mostly pale). Males possess a valvispina and a long and thin apical extension of pseudoceps, while a valvispina is missing in the other three species of Euura that have a long apical extension of pseudoceps (E. abnormi s, E. cornuta, and E. amentorum). Type material examined Lectotype Nematus (Amauronematus) longicauda, here designated FINLAND – Lapin Lääni • ♀; Kilpisjärvi; 69.04° N, 20.81° E; W. Hellén leg; MZH, http://id.luomus. fi/GL.3377. Host plants Salix glauca, S. lanata (Zinovjev & Vikberg 1998). Genetics COI Based on 7 specimens, maximum within-species distance is 1.67% and the nearest neighbour, diverging by a minimum of 0.76%, is Euura abnormis. Nuclear Based on 3 specimens, maximum within-species distance is 0.32% (0.22% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.94%, is Euura abnormis. Distribution and material examined Palaearctic. Specimens studied are from Finland, Norway, and Sweden.
