Description: length: ca. 7 mm; length of fore-body: 2.9; length of head: 0.82; breadth of head: 1.1; length of antenna: 1.7; length of pronotum: 1.2; breadth of pronotum: 1.09; length of elytron: 0.8; breadth of elytra: 1.15. Body black, abdominal segments VII-IX rufescent, all appendages testaceous. Fore-body devoid of microsculpture, abdominal tergites covered with fine and dense reticulation which becomes strong on tergites VII-VIII making the surface dull. Fore-body glabrous, abdomen with sparse, very short pale decumbent hairs. Habitus: Fig. 50h.

Head strongly transverse, eyes moderately large; post-ocular border extending anteriad almost to posterior margin of eye where it forms a small, inconspicuous dentiform angle, and with a relatively broad gutter above the carina; puncturation very irregular, with few, much smaller punctures on frons. Pronotum short, widest at anterior angles, the sides a little convexly rounded to base; lateral margin entirely bordered; puncturation coarse, fairly dense, punctures of variable size. Elytra very short, twice as broad as long, the sides regularly rounded from base to posterior angles, without humeral angles; puncturation about as coarse as that of pronotum, denser on sutural half of each elytron. Abdominal segments exceptionally short, the anterior margin of each without keels but with a transverse row of short longitudinal depressions, the coarse punctures behind these disposed randomly, with no more than the space of two punctures between anterior row of depressions and posterior margins; tergites VII-VIII with only a few scattered very small punctures.

Male: sternite VIII: Fig. 50s8; aedoeagus: Figs 50arl, 50av.

Female: sternite IX: 50vp.

The broad build, very short elytra, short abdominal segments and long process of the ventral blade of the aedoeagus make this species unmistakable.
