Original description. " 1.3/4 mm. Circular in outline, convex, black and somewhat opaque, densely punctate, with short slightly club-shaped setae; the head densely and coarsely punctured, with a feeble median frontal impression; the thorax and elytra are similarly punctate, except that the thorax has large punctures along the basal edge, and elytra for the posterior half are longitudinally rugose; the propygidium is punctured like the disk of the thorax, but the punctuation of the pygidium is smaller, more even and clear; the prosternum and mesosternum are somewhat irregularly punctured, the punctures varying in size; the metasternum has an extremely fine longitudinal median line, and the punctures on the surface are more closely set than those of the mesosternum; along the anterior edge of the first abdominal segment is a row of large punctures."
