Bingham (1903): Dark castaneous brown or black, smooth and shining, except the abdomen, which is conspicuously pubescent; the mandibles, antennae, tibiae and tarsi of the legs yellowish. Head oval, longer than broad; mandibles stout, convex, exteriorly with 7 small but acute teeth; clypeus subtriangular, its anterior margin transverse, posterior margin not clearly defined; antennae comparatively short and stout, densely pubescent, the scape not quite reaching the top of the head ; eyes placed laterally and a little forward, closer to the base of the mandibles than to the top of the head. Thorax short and comparatively broad, the pro-meso- and meso-metanotal sutures very distinct and well-marked, the pro- notum, mesonotum and basal portion of the metanotum convex, the last obliquely truncate at apex, the truncate apical portion much longer than the basal portion; legs short, somewhat stout and densely pubescent. Node of the pedicel low, flat posteriorly, inclined to the front; abdomen broadly oval.

Length: 1.5 - 2 mm
