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 . GoogleMaps

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.
