Distiphallus with 3 processes, 2 slender and pointed, right one wide, larger; large membranous projection under distiphallus. Hypandrium in lateral view with dorsal margin slightly concave and anteroventral margin narrow, not rounded ( Fig. 23 ). Anteroventral hypandrial plates in frontal view narrow, tapered laterally. Membranous projections of margins of anteroventral hypandrial plates with only a small portion visible, not extending to lateral margins of hypandrium; covered with minute hairs ( Fig. 23 ). Anterior surstylus absent, posterior barlike ( Fig. 11 ). Female sternites 6, 7 and 8 almost fused, longer than wide; anterior margin of sternite 6 very slightly sinuate; mid longitudinal portion less sclerotized.
