Description: length: length: ca. 8.5 mm; length of fore-body: 3.2; length of head: 0.8; breadth of head: 1.1; length of antenna: 2.3; length of pronotum: 1.45; breadth of pronotum: 1.15; length of elytron: 1; breadth of elytra: 1.2. Head and pronotum chestnutbrown, elytra brownish testaceous, abdomen a little darker, pale brown; all appendages pale testaceous. Dorsal surfaces shiny, devoid of microsculpture except on keels and grooves at bases of abdominal tergites. Pubescence pale, short, sparse and erect on forebody, longer and decumbent on abdomen. Habitus: Fig. 28h.

Head small, strongly transverse; eyes almost as long as temples, protruberant; groove of post-ocular border broad, displaced to dorsal surface away from lateral margin, merging anteriad with a narrow groove along inner margin of eye, carina obsolete; puncturation obsolete on frons, moderately dense and slightly irregular on vertex, interstices equal to or in parts wider than diameter of punctures. Pronotum behind anterior angles broader than head, the sides gently rounded to base; lateral margin entirely bordered; puncturation coarse and dense, homogeneous, the interstices narrower than diameter of punctures. Elytra short, a little broader than pronotum, humeral angles obsolete, sides distinctly angled at middle, slightly retracted thereafter; puncturation homogeneous, slightly coarser and sparser than on centre of pronotum; keels of anterior margins of abdominal trgites long and salient; puncturation dense and coarse on tergites III-VI, obsolescent on VII.

Male: sternite VIII with a very broad shallow apical emargination flanked on either side by a small elevation forming the apico-lateral angles, the left one prolonged into a small rounded lamellate structure extending beyond apical margin; aedoeagus: Fig. 28av (the apex of dorsal plate apparently broken off).
