243 Euura opacipleuris ( Konow, 1895)

Figs 261–262 , 472

Amauronematus opacipleuris Konow, 1895: 176 . Lectotype designated by Oehlke & Wudowenz (1984).

Diagnosis

Closely related to E. stordalensis , but darker (nearly completely black) and valvula 3 is more triangular in dorsal view than in E. stordalensis (extensively brown around eyes, pale labrum, brownish tibia, and often extensively pale thorax). Lancets which we examined (DEI-GISHym12561, W17802) have clearly or somewhat longer setae (as in E. stordalensis ) than the specimen mentioned by Vikberg (1970a), but otherwise they do not seem to be distinguishable. Differences in the penis valves are not clear. Based on current sampling, nuclear genes separate the Fennoscandian stordalensis from the Alpine opacipleuris , although this may not remain the case if specimens from a wider area are sequenced.

Type material examined

Lectotype Amauronematus opacipleuris

AUSTRIA • ♂; Tirol; SDEI, GBIF-GISHym4098 .

Host plants

Salix reticulata L. (sequenced larva), and possibly other species of dwarf willow ( Lacourt 1999).

Genetics

COI

Based on 3 specimens, maximum within-species distance is 4.1% and the nearest neighbour, diverging by a minimum of 0%, is Euura variator .

Nuclear

Based on 3 specimens, maximum within-species distance is 0.39% (0.5% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.36%, is Euura stordalensis .

Distribution and material examined

Palaearctic. Specimens studied are from Austria, Italy, and Switzerland.
