Hyaline, veins yellow; costa with mainly black setulae, with white setulae at base; R 1 slightly thickened, long, reaching costa behind mid length of wing; lengths of parts of costa between R 2+3 and R 4+5 versus between R 4+5 and M 1 (in mm), 0.42/0.18; crossvein dm-m straight; length of dm-m to apical part of M 4, 0.28/0.47; anal lobe wide; anal angle acute; lower calypter yellow, with whitish cilia; halter pale yellow. Abdomen ( Fig. 4A ). Tergites 1–5 wide and rounded, mostly shiny blackish green, with weak pruinosity; tergites covered with short white vestiture and each with row of white bristles near tergal margins; sternites 2–4 well developed, blackish green, with longitudinal median suture and short setae; sternite 5 entire; other segments retracted; terga 9+10 divided medially into two hemitergites, each bearing 6 thick spines ( Fig. 4H ); cercus brown, elongate-ovate, with a few long white setae.

Male. Unknown.
