Rostrum 0.66 in male and 0.69 in female as high as eye. White microtomentose infra­ocular marking forming a triangle with margin between gena and postgena straight. Mid femur without anteromedial seta. Mid and hind femora wholly yellowish. Mesonotum with medial gray, tripartite stripe; scutellum almost entirely yellow.

Anterior basiphallic process well developed, concave, anterior part bicuspid. Epiphallus large, well developed, extending to base of distiphallus. 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).
