Fig. 279

Nematus tunicatus Zaddach, 1883 in Brischke 1883: 155–156, 166–167. Syntypes ♀♀ (ZSM? Ex Sturm Collection, not located); other specimens probably destroyed ( Blank & Taeger 1998). Type localities: Germany, Nürnberg and Bautzen; Poland, Silesia; Russia, Kaliningrad [Königsberg].

Nematus laevis Brischke, 1883: 155–156 , 174–175. Syntypes ♀♀, probably destroyed ( Blank & Taeger 1998). Type locality: Poland, Jäschkenthal. Synonymy by Konow (1902c).

Amauronematus sollemnis Konow, 1895: 180–181 . Lectotype ♀ (HNHM), designated by Muche (1975), not examined. Type locality: Hungary. Synonymy by Hellén (1970).

Amauronematus forsiusi Enslin, 1915: 384–385 . Lectotype designated below. Synonymy by Hellén (1970).

Diagnosis

Black pterostigma, papilliform serrulae, and mostly or ventrally pale abdomen distinguish the species from the other Euura . Specimens from Iran have a completely black hind tibia: in most other specimens only the apical third is black. Male unknown. Males mentioned by Lindqvist (1961b: figs 4–5) belong to Nematus umbratus (as A. tunicatus , http://id.luomus.fi/GL.2773) and histrio group (as A. sollemnis , http://id.luomus.fi/GL.2761). The penis valve of GL.2761 is most similar to DEI-GISHym84228 ( E. striata ), externally like E. rufa .
