Description: length: 7-8 mm; length of fore-body: 3.4; length of head: 0.8; breadth of head: 1.05; length of antennae: 2.3; length of pronotum: 1.32; breadth of pronotum: 1.4; length of elytron: 1; breadth of elytra: 1.2. Centre of head black, surrounding areas rufescent, pronotum black, elytra reddish-brown, abdomen brown, centre of tergites broadly infuscate; palpi, antennae and legs entirely testaceous. Dorsal surfaces devoid of microsculpture. Pubescence pale, short and sparse on fore-body, longer, decumbent and dense on abdomen. Habitus: Fig. 29h.

Head moderately transverse; eyes large, slightly longer than temples, protruberant; temples gently rounded to neck, but not coarctate with base; groove of post-ocular border a little displaced from lateral margin to dorsal surface; puncturation of disc sparse, mixed, with a very few rather small umbilicate punctures and more numerous minute simple punctures. Pronotum moderately elongate, behind anterior angles broader than head, the sides retracted in almost straight lines to narrow base; lateral margins entirely bordered; puncturation coarse, dense, not forming longitudinal series, the interstices nearly everywhere narrower than diameter of punctures; punctures a little elongate on centre of disc, smaller and rounder on sides. Elytra small, humeral angles obsolete, the sides rounded but distinctly angulate at mid-length; puncturation homogeneous, a little finer and denser than that of pronotum, the punctures round and deep. Keels and grooves of anterior margins of abdominal tergites obsolescent on tergite III, pronounced on tergites IV-VIII; puncturation of tergites homogenous, coarse and dense on segments III-VI, evanescent on VII-VIII.

Male: abdominal sternite VIII: Fig. 29s8, the apical margin with an asymmetrical emargination, the surface of sternite with a pair of elevations, the right one cariniform, the left with a claw-like projection; aedoeagus: Figs. 29arl, av.

Female: sternite IX: Fig. 29vp.
