Pachynematus glabriceps Lindqvist, 1949: 84–85 . Syn. nov.

Diagnosis

The most similar species is E. uda , which is best distinguished by examination of saws and penis valves. In E. uda , tangium of lancet is more elongate, paravalva of penis valve is ventrally straight (concave in E. punctifrons ) and anterior margin of paravalva below valvispina is straight or concave (convex in E. punctifrons ). Euura uda tends to have also a larger subapical tooth of the claw than E. punctifrons .

Female

4.4–5.0 mm. Head black; labrum pale; clypeus black or slightly pale; supraclypeal area black; thorax black; pronotum black; tegula pale; pterostigma pale; metafemur mostly black to mostly pale; metatibia pale; hind tarsus pale to black; abdomen nearly completely black; valvula 3 black with dorsobasal pale area; mesepisternum smooth; claws with small subapical tooth; valvula 3 in dorsal view narrow and apically acute.

Male

4.5 mm. Head black; labrum pale; clypeus black or slightly pale; supraclypeal area black; thorax black; pronotum black; tegula black; pterostigma pale; metafemur black or slightly pale; metatibia pale; hind tarsus black or brown; abdomen black; sternum 9 pale; mesepisternum smooth or slightly matt; claws with minute subapical tooth.
