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.
