Forecoxa sparsely microtomentose; forebasitarsomere variable, some species yellow, similar to mid- and hindtarsi, other species black, unicolorous with other tarsomeres. Abdomen: Male terminalia: Epandrium with high cercal cavity, making dorsal portion of epandrium narrow; and presurstylus lacking presurstylar basomedial process, with large, medial seta (sometimes 2) and medial surface rounded, not concave; postsurstylus lacking rod-like process; pre- and postgonites fused, elongate.
