Eyes consisting of only 3 or 4 scarcely pigmented ommatidia. Clypeus convex in the middle, depressed on the sides. Antennal scapes reaching to the middle of the sides of the head; funicular joints 2-10 as long as broad, first joint as long as the three succeeding joints together, terminal joint as long as the two preceding. Thorax including the neck about twice as long as broad, pronotum as broad as long; mesonotum convex, rounded subtriangular, broader than long; epinotum nearly as broad as the mesonotum, its base broader than long, rounding into the longer, feebly concave and nearly perpendicular declivity. Petiolar scale high, moderately thin, inclined forward, narrowed above, with rounded, entire, compressed superior border. Gaster elongate-elliptical. Legs rather stout.

Hairs and pubescence pale yellow, the former long, erect and conspicuous on the gaster, shorter and much sparser on the head and thorax, long on the clypeus; hind tibiae with a few long and oblique hairs on their extensor surfaces. Pubescence dense, especially on the head, thorax, scapes and legs, much more dilute on the gaster; appressed except on the thoracic dorsum.
