♂♀. Derm black, with uniform dense sandy-brown scaling above and opalescent scaling beneath.

Head short, not transversely impressed, the temples less than half as long as an eye; frons with the median stria partly obscured by scaling and with a few erect spatulate setae on each side; eyes strongly convex, highest behind the middle. Rostrum similar in the two sexes, a little longer than broad, about as wide at the genae as at the base, and with the sides slightly sinuate; dorsum with a high bare median carina that expands apically into a broad bare epistomal area, which is unevenly punctate and not marginate, the epistomal setae being rather sparse and narrow, the areas on each side of the carina densely squamose and obliquely impressed in the middle; mandibles less densely setose than usual and without scales; mentum with only a single row of setae along the apical margin. Antennae black, densely squamose throughout, scape straight, widening from base to apex; funicle with joints 1 and 2 equal, 3 as long as broad, 4–7 subequal and transverse; club with the basal joint pedunculate. Prothorax transverse (2:3), broadly rounded laterally in the basal half, widest at one-third from base, the basal angles rounded obtuse angles, not constricted apically, the base shallowly bisinuate with the median lobe short and broadly rounded; dorsum smooth, with dense overlapping striolate scales and short appressed spatulate setae, concealing the median stria, and with a large shallow impression in the basal angles.
