Euura pallens (Konow, 1903)

Pteronus pallens Konow, 1903: 310 (key). Type locality: Irkutsk, Russia (LT).

Similar species.

Most similar species are Euura sylvestris and Euura respondens , from which it differs by having more prominent serrulae (cf. Figs 7B , 9C, D ). It is possible that Euura pallens is a synonym of Euura respondens (shape of the basal sutures of the lancet seem to be most similar to this species), even though the serrulae seem to be more prominent than in other specimens of Euura bergmanni group examined so far. Lindqvist (1972) synonymised Pteronidea straminea , which we treat as a synonym of Euura sylvestris , with Euura pallens . Male unknown.
