148 Euura epilosa ( Lindqvist, 1970)

Figs 147–148

Pteronidea epilosa Lindqvist, 1970: 102–103 .

Diagnosis

The colouration and the lancet of E. epilosa are most similar to those of E. nigricornis and E. miliaris , but its antenna is distinctly shorter.

Type material examined

Holotype Pteronidea epilosa

RUSSIA – Irkutskaja oblast • ♀; Irkutsk, Oljhonsk, Popovo ; 52.741° N, 106.309° E; 22 May 1967; B.N. Verzhutskii leg.; collected from Spiraea media ; MZH, http://id.luomus.fi/GL.5142.

Notes

Recently discovered in Europe. A single female was collected in Bulgaria in 2022 by E. Heibo close to Spiraea sp. and several larvae on Spiraea media F.Schmidt in Slovakia by A. Lendel (Ladislav Roller, pers com.). Male unknown. The Euura epilosa group includes also E. brachycera ( Lindqvist, 1975) (known from Irkutsk oblast and Primorsky Kray, Russia) and possibly Nematus mandshuricus Zhelochovtsev & Zinovjev, 1994 and Euura vastidens ( Lindqvist, 1975) . Euura epilosa , E. brachycera and N. mandshuricus have been reared from Spiraea , but E. vastidens from Dasiphora fruticosa .

Host plants

Spiraea media ( Verzhutskii 1981) . One generation per year.

Genetics
