Postmetacoxal bridge incomplete. Dorsal lobe of calypter with a fringe of short and rather dense pile. Tergite II somewhat longer than wide, slightly constricted anteromedially. Callus of tergite I absent. Callus of sternite I elongate, oval and partly sclerotized. Genitalia ( Figs 148–150 , 157–165 ): dorsal lobe of surstylus elongate, ventro-basal lobe large and rounded to rectangular shaped; dorsal lobe with scattered pile on apico-dorsal surface and setose on ventral surface; epandrium round with large membranous area; cercus elongate and triangular-shaped; surstylar apodeme rectangular, not fused, entirely but slightly sclerotized; hypandrium broad, with simple rounded superior lobe and short elongate lingula.
