Abstract: 294 Euura distinguenda (Enslin, 1915) Figs 308, 533 Amauronematus distinguendus Enslin, 1915: 381. Lectotype designated below. Diagnosis Females are most similar in colouration (mostly black body and black pterostigma) and lancet structure to E. toeniata, but the malar space is about 1.0–1.2 times as long as diameter of front ocellus (more than 1.2 times in E. toeniata). Males are coloured similarly to the females and in combination with examination of the penis valves can be reliably separated from the other species of Euura. Type material examined Lectotype Amauronematus distinguendus, here designated GERMANY – Sachsen • ♀; Tharandt; 50.97° N, 13.53° E; W. Baer leg.; reared ex larva on Salix sp.; ZSM, GBIF-GISHym3047. Host plants Salix fragilis, S. phylicifolia (Kangas 1985), S. pentandra, S. acutifolia Willd., S. triandra. Genetics COI Based on 5 specimens, maximum within-species distance is 1.98% and the nearest neighbour, diverging by a minimum of 3.05%, is Euura anthracina. Nuclear Based on 4 specimens, maximum within-species distance is 0.81% (0.07% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.41%, is Euura anthracina. Distribution and material examined Palaearctic. Specimens studied are from Finland, Germany, and Russia.
