Nematus insignis Hartig, 1840: 22 . Lectotype designated below.

Nematus superbus Gradl, 1881: 299–300 . Holotype ♂ (NMPC?), not examined. Type locality: Czech Republic, Egerland. Synonymy by Konow (1898).

Diagnosis

Its large size and colouration distinguishes the species from the other Euura . In females, the antennae are pale in the middle and the middle abdominal terga are usually reddish. In males, flagellomeres 2(3)–7 are pale and the middle or most terga (except first tergum) are usually reddish. Both males and females have a black pterostigma and pale costa.

Type material examined

Lectotype Nematus insignis , here designated

GERMANY – Niedersachsen • ♀; Klausthal [Clausthal-Zellerfeld]; 51.80° N, 10.34° E; W. Saxesen leg.; NFVG, GBIF-GISHym4690 . GoogleMaps

Host plants

Picea abies is the main host in Europe, but P. pungens Engelm. is also used ( Kula et al. 2016).

Genetics

COI

Based on 3 specimens, maximum within-species distance is 0.15% and the nearest neighbour, diverging by a minimum of 6.23%, is Euura scutellata .

Nuclear

Based on 2 specimens, maximum within-species distance is 0.02% (0.2% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.26%, is Euura scutellata .

Distribution and material examined

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