Elytral spots arranged as follows: spot 1 triangle, situated on humeral callus, spot 2 subrounded, posterior to the transverse middle line, nearer the suture, spot 3 small, oblong, and confluent with the border, spot 4 small, prior apex, confluent with the border (Fig. 30). Underside black, except legs and abdomen reddish brown.

Head small, 0.38 times elytral width (HW/EW=1:2.64). Punctures on frons fine, separated by 0.5-1.0 times their diameter, with thin, yellow white pubescence. Eyes large and almost oval, finely faceted, the widest interocular distance 0.56 times head width. Pronotum 0.60 times elytral width (PW/EW=1:1.67). Punctures on pronotum and elytra close, separated by 0.5-1.0 times their diameter, with thick, yellowish pubescence. Underside coarsely punctate, with sparse yellowish pubescence.

Male genitalia: Penis short, penis capsule with an extremely expanded outer process and a short inner process (Fig. 65). Apex of penis with membranous appendage (Fig. 66).
