Comments. The species is quite variable in size and colour. The body-length varies from 1.0 to 1.35 mm, the width from 0.54 to 0.78 mm, and the dorsoventral diameter from 0.58 to 0.85 mm. The head, pronotum and elytra are usually uniformly reddish dark brown or black, the apical margins of the elytra may be lightened, the abdomen and the legs are lighter than the thorax and most of the elytra, the apical abdominal segments usually light brown, the tibiae and tarsi as light or lighter than the femora, and the antennae distinctly lighter than the legs. The length/width ratios of the antennomeres are about as: III 25/10: IV 30/10: V 35/10: VI 33/10: VII 42/13: VIII 27/12: IX 40/18: X 40/20: XI 55/21. The scutellum is in some specimens almost completely concealed, the elytra may be not or weakly iridescent, the metanepisterna are 0.05-0.07 mm wide. The aedeagus is as in Figs XY, 0.26-0.40 mm long.
