Description: length: 8 mm; length of fore-body: 3.4; length of head: 0.92; breadth of head: 1.75; length of antenna: 2.32; length of pronotum: 1.25; breadth of pronotum: 1; length of elytron: 1.2; breadth of elytra: 1.1. Body black; appendages testaceous. Dorsal surfaces devoid of microsculpture except narrowly on anterior margins of abdominal tergites. Pubescence short, pale, erect. Habitus: Fig. 39h.

Head moderately transverse; post-ocular carina salient, forming a dentiform angle at posterior margin of eye; disc entirely but irregularly punctate, leaving only a small space of a couple of missing punctures on vertex. Pronotum strongly elongate, the sides slightly concave between anterior and posterior angles; lateral margins entirely bordered by a fine sharp carina; puncturation coarse and dense, with pair of discal series of seven punctures made a indistinct by the density of surrounding punctures and the presence of a few punctures between the series. Elytra elongate, but hind wings reduced and nonfunctional; humeral angels reduced but not completely obsolete, the sides dilated to a point ¾ from base; puncturation coarse and farly homogeneous; four punctures on lateral margins behind humeral angles asperate, forming small tubercles. Punctures of abdominal tergites coarser than that of elytra and dense, disposed randomly; keels of anterior margins of tergites short, becoming obsolete after tergite IV.

Male: sternite VI with a large symmetrical apical emargination; sternite VII with a large ogival impunctate area; sternite VIII (Fig. 39s8) with a rather narrow, deep emargination, the area anterior to this depressed and impunctate; aedoeagus: Fig. 39arl

Female: sternite IX: Fig. 39vp.
