Diagnosis. Distinguished by the combination of brownish pronotum and venter, and distal two antonnomeres in the males.

Re-description. Size: Total length (without labrum) 6.2 mm- 7.4 mm, (mean= 6.6 mm, n=5). Head: Black, frons between orbital plates brownish in some specimens. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 383 , female Fig. 384 ) as wide as long, yellowish, with six apical teeth one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally to elytral shoulders in male, somewhat shorter in the females, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, all the other antennal segments brownish, the distal two darker. Distal two elements enlarged in males. Clypeus glabrous. Frons smooth, with a transverse furrow in the posterior part of the orbital plates. Thorax: Pronotum brownish, as long as wide, constricted in front and at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining brownish black, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 379 ).
