Description: length: 7-7.3 mm ; length of fore-body: 2.6; length of head: 0.65; breadth of head: 0.9; length of antenna: 1.7; length of pronotum: 0.17; breadth of pronotum: 1.1; length of elytron: 0.8; breadth of elytra: 1.2. Head, pronotum and abdomen black, elytra piceous, sometimes ( type ) dark reddish-brown; palpi, antennae and legs entirely testaceous. Head shiny but, especially in anterior half, distinctly micro-reticulate, pronotum and elytra devoid of microsculpture; abdominal tergites with dense transverse micro-stiation. Frons with some short pale pubescence, rest of body glabrous. Habitus: Fig. 17h. Head moderately transverse; eyes large, about as long as temples, protruberant; groove of post-ocular border narrow, inconspicuous, adjacent to carina on lateral margin; temples broadly rounded, almost coarctate with base; puncturation of disc very sparse, with half a dozen small shallow frontal punctures and about six more, deeper punctures on vertex. Pronotum relatively short, at anterior angles broader than head, the sides rounded to narrow base; lateral margins entirely bordered; puncturation dense, coarse, homogeneous. Elytra short, broad, humeral angles completely obsolete, posterior margin scarcely concave; puncturation coarse and dense, comparable to that of pronotum but punctures round, sparser antero-laterad. Keels and grooves of anterior margins of abdominal tergites short, obsolescent on tergite III, long and pronounced on IV-VII; puncturation of tergites sparse and irregular, on tergite VI consisting only of a transverse anterior row and a posterior marginal row of punctures, VII almost impunctate. Male: abdominal sternite VIII: Fig. 17s8; aedoeagus: Figs. 17arl, av. Female: sternite IX: Fig. 17vp.
