Decanematus longiserra Malaise, 1931b: 31–32 .Secondary homonym of Nematus longiserra Thomson, 1863 [= Euura longiserra ( Thomson, 1863) ].

Amauronematus malaisei Hellén, 1970: 7 . Replacement name for Decanematus longiserra Malaise, 1931.

Diagnosis

Females are most similar to E. erecta : see differences mentioned under that species. Penis valves are very similar to E. leucolena and E. rectiserra . Dorso-apically, the valviceps might be more expanded in E. malaisei than in E. leucolena and E. rectiserra .

Female

5.0 (6.5) mm. Head black; labrum black or brown; clypeus black; supraclypeal area black; thorax black; pronotum black; tegula black; pterostigma centrally paler than externally; metafemur black or apically pale; metatibia brown or pale; hind tarsus black; abdomen black; hypopygium black or posteriorly slightly pale; valvifer 2 at least partly pale or brown; tergum 9 black to extensively pale; tergum 10 black or slightly pale; valvula 3 basally slightly pale; cerci pale with darkened tip; mesepisternum slightly matt; valvula 3 long, in dorsal view gradually narrowing, with acute tip.

Male

4.0– 4.5 mm. Head black; labrum black or brown; clypeus black; supraclypeal area black; thorax black; pronotum black; tegula black; pterostigma centrally paler than externally; metafemur black or apically pale; metatibia brown or pale; hind tarsus black; sternum 9 pale; mesepisternum slightly matt; projection of tergum 8 small.

Type material examined

Holotype Decanematus longiserra

RUSSIA – Kamchatka oblast • ♀; Klutchi [Klyuchi]; 56.32° N, 160.85° E; R. Malaise leg.; NHRS, NHRS-HEVA000006442 . GoogleMaps

Notes

Holotype length 6.5 mm, or 6.9 mm including valvula 3.

Host plants

Genetics

COI

Based on 6 specimens, maximum within-species distance is 3.75% and the nearest neighbour, diverging by a minimum of 0%, is Euura leucolena .

Nuclear

Based on 6 specimens, maximum within-species distance is 0.59% (0.51% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.17%, is Euura erecta (ZMUO.063230).

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Russia.
