Description.

Male (n = 1). Length of wing 4.2 mm.

Head blackish brown with numerous pale setae. Three ocelli, with lateral ones almost touching compound eyes, separated from the eye margins by their own diameter. Clypeus blackish, with setae pale. Mouthparts light brownish. Palpus brownish yellow, basally and apically darker. Scape, pedicel and all flagellomeres dark brown. Flagellomeres cylindrical, flagellomeres 1 to 7 about twice as long as broad, apical flagellomeres (8 to 14) slightly conical, three times as long as broad.

All parts of thorax blackish brown. All bristles and setae yellowish white. Scutellum with several marginal and submarginal pale bristles and with numerous setae. Antepronotum and proepisternum with pale bristles and short dark setae. Upper part of antepronotum with a strong pale bristle reaching to the ocellus. Laterotergite and other pleural parts bare. Haltere pale yellow.

Legs. All coxae entirely yellow. Femora yellow with hind femur brownish only around its tip. All trochanters blackish brown. Tibiae and tarsi yellow, tarsal segments seemingly brownish because of dense setulae. Fore tibia apicomedially with a semicircular tibial organ (anteroapical depressed area), without strong setae, only densely covered with fine setulae. Mid tibia with 5 anterior, 4 dorsal, 3 anteroventral and 5-6 posterior setae. Hind tibia with 16 anterior, 12 dorsal, 5 anteroventral and 6 posterior setae.

Wings hyaline, unmarked. Radial veins and r-m brown, other veins paler while m-stem and the base of M1 are faint, almost not traceable. Sc, Rs and basal third of cu-stem asetose, the other veins setose. Costa reaches to 0.45 of the distance between R5 and M1. Sc ends in R at the level of beginning of m-stem. Posterior fork begins before anterior fork, approximately at the level of the middle of r-m.

Abdomen all dark brown. Terminalia (Figs 1-3) dark brown except lighter gonostyli. Tergite 9 in the shape of a rounded square, about as long as broad (Fig. 2). Posteroventral margin of gonocoxites with lateral projections and with two patches of short setae medially (Fig. 1). Gonostylus subtriangular with a row of black megasetae along its ventral margin (Fig. 3).
