Description
Male (n = 2)
MEASUREMENTS. Length of wing 4.2 mm.
HEAD. Blackish brown with numerous pale setae. Three ocelli, lateral ones almost touching compound eyes, separated from eye margins by less than half of their own diameter. Clypeus blackish, with setae pale. Mouthparts light brownish. Palpus brownish yellow, basal segment and apical part of last palpomere darker. Scape, pedicel and all flagellomeres dark brown. Flagellomeres cylindrical, flagellomeres 1 to 7 about twice as long as broad, distal flagellomeres (8 to 14) slightly conical, 2.5 to 3 times as long as broad.
THORAX.All parts of thorax blackish brown, with light setae. Scutellum with numerous setae and several submarginal pale bristles about twice as long as scutellum. Antepronotum and proepisternum with pale bristles and short darker setae. Laterotergite and other pleural parts bare. Haltere pale yellow.
LEGS. All coxae yellow, with basal third darkened. Femora mostly yellow, fore and mid femur dark along ventral margin, more extensively in proximal third; similarly hind femur, brownish also around tip. All trochanters blackish brown. Tibiae and tarsi yellow, tarsal segments seemingly brownish because of dense setulae. Fore tibia apicomedially with semicircular tibial organ (anteroapical depressed area), without strong setae, only densely covered with fine setulae.
WINGS. Hyaline, unmarked. Radial veins and r-m dark brown, other veins paler, basal parts of m faint, almost not traceable. Sc, Rs and basal third of cu-stem asetose, other veins setose. Costa reaches to 0.45 of distance between R 5 and M 1. Sc ends in R slightly beyond level of beginning of m-stem. Posterior fork begins before anterior fork, approximately at level of basal third of r-m.
ABDOMEN. All dark brown.
TERMINALIA (Figs 4 A–E, 7D). Dark brown except lighter gonostyli and posterior margin of gonocoxites. Tergite 9 about as long as broad, slightly narrowing towards base, with slightly concave posterior margin. Posteroventral margin of gonocoxites without lateral projections, with distinct U-shaped medial incision and narrow digitiform medioventral process. Gonostylus simple, slightly bulging medially, with aggregation of small setae at mediobasal corner and with characteristic sickle-like posterior projection, with prominent basal setae at its ventral and dorsal sides. Cercus with 14 combs of retinacula.
Female
Unknown.
