Extract

A small robust species, length 1.5-2.5 mm.

Front of the male deeply concave, clothed with short bristle-like hairs, sparsely granulate-punctate, surface opaque, with a long, shining, median carina; second suture of the antennal club subtransverse. Pronotum wider than long, 5.5:3.5; sides slightly rounded, narrowing on the anterior half, constricted behind the anterior margin; the constriction extends across the dorsum, widening on the disk thereby simulating a wide, deep impression on the anterior third; anterior margin is broadly rounded; the surface is moderately clothed with short setae and the punctures are large, dense, and deep.
