Nematus melanosternus Hartig, 1840: 27 . Lectotype ♂ (ZSM), designated by Taeger & Blank (1998), not examined. Type locality: Austria, North Tyrol, Stübaier Alps. Synonymy by Taeger & Blank (1998). Primary homonym of Nematus melanosternus Serville, 1823 [= Euura punicea ( Christ, 1791) ].

Nematus dissimilis Förster, 1854a: 314–315 . Lectotype ♂ (ZSM), designated by Taeger & Blank (1998), not examined. Type locality: Germany, Nordrhein-Westfalen, Aachen area.

Diagnosis

Most similar to E. platystigma and E. semiopaca . Strong subapical tooth (as long as or longer than apical tooth) of claws should distinguish the species from E. platystigma and sometimes also from E. semiopaca . Extensively pale head and dorsally pale mesepisternum should distinguish the females from E. semiopaca (mostly black head and thorax). Penis valves are similar to E. semiopaca , but the subapical tooth of claws is perhaps larger in E. dissimilis than in E. semiopaca . In addition, at least some of the males of E. semiopaca have a black mesepisternum (dorsal half pale in E. dissimilis ).

Females and males: antenna black, head extensively pale around eyes, dorsal half of mesepisternum pale, claws with large subapical tooth or bifid, abdomen ventrally pale, terga dorsally partly pale.

Host plants

Unknown.

Genetics

COI

Based on 5 specimens, maximum within-species distance is 0.46% and the nearest neighbour, diverging by a minimum of 4.26%, is Euura sordidiapex .

Nuclear

Based on 2 specimens, maximum within-species distance is 0.39%. The nearest neighbour, diverging by a minimum of 1.05%, is Euura myosotidis .

Distribution and material examined

Palaearctic. Specimens studied are from France, and Germany.
