Head longer than broad; mandibles shining, narrow, the masticatory margin armed with 4 teeth; clypeus convex in the middle, slightly shining, the carinae obtuse; antennae short, the scape not extending to the top of the head; eyes a little below the middle of the sides of the head. Thorax anteriorly broad, narrowing posteriorly, the anterior margin of the pronotum arched, the anterior lateral angles of the thorax a little pronounced; meso-metanotal suture slight; basal face of metanotum long, narrow, compressed, convex, passing into the apical portion by a rounded curve, and bearing an impression giving the posterior lateral angles of the metanotum an appearance of being subtuberculate. Pedicel: 1st node conical, anteriorly shortly petiolate: 2nd node broader than long and above much broader than the 1st; abdomen elongate, oval.
