Cercus with abundant, stout setae dorsally; epandrium apically curved or angled medially. Gonostylus rectangular, wide basally, 2/3–3/4 as wide as long in lateral view, narrow apically and hooked. Aedeagal sheath membranous, moderately inflated dorsally (epiphallus); distiphallus tubular, horizontal, slightly sigmoid. Gonocoxite admedial process long and narrow with 1 or 2 seta-like bristles apically. Female . Genital fork goblet-shaped with narrow sclerotized arms and membranous base, base usually folded posteriorly. Spermatheca reflected, base large, narrowed apically; ducts join common bursa separately.
