). The male sternite 9 is broadly rounded and shovel-like. The gonocoxites 9 are subtrapezoidal with posterior corners blunt. The gonocoxites 11 are elaborated, with two differentiated portions: the upper portion is posteriorly produced as lateral hook-shaped processes, and the lower portion as two narrow, arched, lateral sclerites, medially fused; in lateral view curved, elongated, and narrow with the distal part representing the gonostyli 11, which are dorsally connected to the upper portion and covered with minute spinulae. The membrane between gonocoxites 11 and sternite 9 is covered with minute spinulae. The female sternite 8 is subpentagonal, posteromedially produced into a short and blunt lobe. The gonocoxites 8 form an ovoid sclerite, located just beneath sternite 8; the bursa copulatrix is bilobed with the distal margin shallowly incised in ventral view.
