Genus Pseudcolenis Reitter, 1885

See Daffner (1988a) and Newton (1998) for synonymy and references. Type species: Pseudcolenis hilleri Reitter, 1885 (monotypy).

Diagnosis. Body convex, glabrous, almost concolorous, brown to dark brown. Head weakly but densely striolate, with some fine sparse punctures. Antenna ( Figs. 4–5 ) relatively slender; antennomere 8 longer than half of 9; 7 and 9–11 pubescent with long or short setae and 1–6 and 8 sparser. Mandible asymmetrical, with molar lobe bearing well developed grinding surface. Clypeal line ( Fig. 2 ) fine, apical margin of clypeus not emarginate. Labrum ( Fig. 2 ) with slight apical emargination. Eyes ( Fig. 2 ) oval and projected, sharply narrowed behind eyes. Pronotum weakly, densely and transversely striolate, weakly punctate. Elytra with weak and dense, or strong and sparse transverse strigulae, weakly or strongly punctate, rows of punctures present or not. Mesosternum with medial carina; mesocoxal cavity distant form mesepimeron. Tarsal formula 5-4- 4 in both sexes, protarsomeres 1–4 more dilated in male, meso- and metatarsomere 1 ( Figs. 10–11 ) distinctly longer than 2. Aedeagus ( Figs. 12–15 ) elongate, usually slender. Spermatheca shape ( Figs. 17–18 ) varies.
