Tibiae with yellow scales. Wing ( Fig. 9 ) half infuscate; hyaline part including entire cell r4, most part of cell m2, part of r2+3, r5, m1, cu-a1, and dm, and little part of cells r1, cup, and a; hyaline part of cell r1 nearly semicircular; hyaline part near base of r4 very small, triangular; infuscate part with an extended part from cell m1 into cell m2 and very close to wing margin. Halteres brown; knob pale.

Abdomen black with brown pollen. Hairs on abdomen white and black; dorsum with long dense black hairs laterally except tergites 1, 4 and 6 with white hairs; tergites with a row of white hairs on the margin; dorsum with sparse black hairs except tergite 4 with dense white hairs; tergites 9–10 with short yellow hairs. Sternites with yellow recumbent hairs and black erect hairs.

Male genitalia ( Figs. 59–64 ). Epandrium subquadrate, distinctly longer than high, and with distinct lateral extension at base in lateral view, epandrium distinctly wider than high in posterior view; gonocoxa with slightly narrow apical portion, with a narrow middle incision apically and apicolateral lobes somewhat acute apically in ventral view; gonostylus with a basal process, its acute tip strongly curved in lateral view; epiphallus tumid at middle and narrowing near base, distiphallus short subtriangular with an obtuse tip in dorsal view, distiphallus long, slightly narrowing apically in lateral view.
