Euura anthracina ZMUO.

293 Euura anthracina (Lindqvist, 1959) Figs 307, 532 Amauronematus anthracinus Lindqvist, 1959d: 11. Amauronematus macrophthalmus Lindqvist, 1959d: 13–14. Syn. nov. Amauronematus varians Lindqvist, 1962a: 120–121. Syn. nov. Diagnosis Females (6.5–8.0 mm) are most similar to E. hyperborea, but pronotum and tegula are distinctly pale (black in E. hyperborea) and the hairs on head and thorax are somewhat shorter. Males are not clearly distinguishable from melanocephalus group species with a pale pterostigma (E. cadderensis, E. ferruginea, E. kangasi). Type material examined Holotype Amauronematus anthracinus FINLAND – Lapin Lääni • ♀; Kilpisjärvi; 69.04° N, 20.81° E; 9 May 1951; E. Lindqvist leg.; MZH, http://id.luomus.fi/GL.3409.

Notes Best morphological match: DEI-GISHym20974. COI sequence (658 bp) of the holotype is identical to ZMUO.037292. Host plants Salix spp. Genetics COI Based on 9 specimens, maximum within-species distance is 4.1% and the nearest neighbour, diverging by a minimum of 0.46%, is Euura hyperborea. Nuclear Based on 7 specimens, maximum within-species distance is 0.4% (0.23% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.41%, is Euura distinguenda. Distribution and material examined Palaearctic. Specimens studied are from Finland, Norway, and Sweden.
