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. GoogleMaps

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.
