Amauronematus pravus Konow, 1895: 176–177 . Lectotype designated by Muche (1975). Amauronematus torneensis Malaise, 1921b: 123–124 . Lectotype designated below. Syn. nov.

Diagnosis

A rather large species (females 6.5–8.0 mm, males 6.0–7.0 mm) whose females are usually extensively pale. The serrulae of the lancet are most similar to E. flavescens , but a pale area on the dorsobasal part (next to the suture) of the basalmost annulus is missing in E. pravus . Externally rather similar to E. renei , but the median mesoscutal lobe has a large triangular black fleck (pale in E. renei ) and antennae are black in E. pravus (ventrally pale in E. renei ).

Female

6.5–8.0 mm. Head extensively to mostly pale; labrum, clypeus and supraclypeal area pale; flagellum black; thorax dorsally black to extensively pale, ventrally extensively or nearly completely pale; pterostigma uniformly pale or with dark margins; abdomen dorsally mostly black, ventrally mostly black to completely pale; metafemur and metatibia pale; hind tarsus black or brown; mesepisternum distinctly or slightly matt; claws bifid; valvula 3 rather truncate in lateral view (as in E. brevivalvis ).

Male

6.0–7.0 mm. Head extensively pale around eyes to nearly completely black; labrum pale; clypeus slightly or extensively pale; supraclypeal area black or pale; thorax black; pronotum and tegula black to extensively pale; pterostigma pale with dark margins; metafemur extensively black to completely pale; metatibia pale; hind tarsus black or brown; abdomen dorsally nearly completely black, ventrally black or slightly pale; sternum 9 pale; mesepisternum distinctly or slightly matt; claws bifid; apical projection of tergum 8 small, about as broad as long or broader than long.
