Abstract: 290 Euura rectiserra (Lindqvist, 1971) Figs 304, 531 Decanematus rectiserra Lindqvist, 1971b: 8. Diagnosis Females can be recognized mainly by the short valvula 3 and straight lancet with about 14 annuli and flat serrulae. The smooth mesepisternum can also help to distinguish the females from the similar E. leucolena. Males might not be distinguishable from E. leucolena. Macek et al (2020) reported this species under the name Amauronematus leucolenus. Female 4.5–5.5 mm (n = 2). Head black or weakly brown around eyes; labrum brown or pale; clypeus partly pale; supraclypeal area black; thorax black; pronotum posteriorly slightly or extensively pale; tegula slightly or extensively pale; pterostigma brown or centrally paler than externally; metafemur mostly black or pale; metatibia brown or pale; hind tarsus black; abdomen black; tergum 9 and valvifer 2 black or slightly pale, hypopygium partly brown; mesepisternum (usually?) smooth. Male 4.0 mm (n = 2). Head black; labrum brown or pale; clypeus black; supraclypeal area black; thorax black; pronotum black or slightly pale posteriorly; tegula black; pterostigma centrally paler than externally; metafemur mostly black to mostly pale; metatibia brown or pale; hind tarsus black; sternum 9 pale; mesepisternum (usually?) smooth; projection of tergum 8 small. Type material examined Holotype Decanematus rectiserra FINLAND – Central Ostrobothnia • ♀; Kaarlela; 63.819° N, 23.567° E; 3 Jun. 1968; J. Kangas; MZH, http://id.luomus.fi/GL.9211. Host plants Salix aurita. Genetics COI Based on 4 specimens, maximum within-species distance is 4.41% and the nearest neighbour, diverging by a minimum of 0%, is Euura viduatoides. Nuclear Based on 4 specimens, maximum within-species distance is 0.42% (0.44% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.31%, is Euura leucolena (ZMUO.038899). Distribution and material examined Palaearctic. Specimens studied are from Finland.
