Extract

Length 2.5 mm., width 1.1 mm. Pronotum and elytra equal in width, sides straight and parallel, elytra arcuately narrowed on the caudal third, very broadly obtuse behind; dark reddish brown; pubescence sparse, erect and yellow, more evident about the apex of the pronotum and on the elytral declivity.

The head has the frons broadly, feebly convex, the median line feebly carinate with a narrow, transverse epistomal impression, the entire surface subopaque from minute reticulations, marked with sparse, coarse, shallow punctures with minute setae on the caudal half, more finely and closely granulatepunctate in front, the punctures bearing long yellow hairs erect on the frons, longer and recumbent from the transverse impression, forming the epistomal fringe, the epistomal margin smooth, narrow and feebly elevated; the eyes with a deep triangular emargination.
