263 Euura krausi ( Taeger & Blank, 1998)

Figs 290 View Figs 290–293 , 488 View Figs 478–491

Amauronematus krausi Taeger & Blank, 1998: 251–252 .

Diagnosis

Flat serrulae and usually characteristic colouration of the abdomen (pale colouration dorsally distinctly expanding posteriorly) enable identification of the females from the others in the vittata group. Male penis valves are most similar to those of E. tillbergi , but externally males of E. krausi tend to be paler.

Type material examined

Holotype Amauronematus krausi

GERMANY – Hessen • ♀; Climbach ; 50.67° N, 8.82° E; 27 May 1986; H. Weiffenbach leg.; reared ex larva on Populus tremula ; SDEI, GBIF-GISHym4094 . GoogleMaps

Host plants

Populus tremula ; also P. alba L., according to Macek et al. (2020).

Genetics

COI

Based on 12 specimens, maximum within-species distance is 3.23% and the nearest neighbour, diverging by a minimum of 0%, is Euura tillbergi .

Nuclear

Based on 8 specimens, maximum within-species distance is 0.67% (0.8% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.12%, is Euura tillbergi .

Distribution and material examined

Palaearctic. Specimens studied are from Bulgaria, Finland, Germany, Russia, and Sweden.
