Redescription.

General body colouration: dark brown head, obscure yellow thorax with greyish dorsum, dark brown abdomen. Body length of male ~ 4.5 mm, of female 4.8–7.9 mm. Wing length of male 5.2 mm, of female 5.6–8.6 mm.

Head. Dark brown, paler posteriorly, narrowly light grey along eye margin, covered with dense grey pruinosity and sparse yellowish setae. Vertex with low, slightly darker, rounded tubercle. Eyes widely separated, distance between them at base of antennae slightly exceeds length of scape. Antenna (Fig. 53 View Figures 53–57 ) short, 0.6 mm long in male, 0.7 mm in female, reaching slightly beyond frontal margin of prescutum, if bent backwards. Scape yellowish brown to brown in male, covered with grey pruinosity, nearly cylindrical, ~ 2 × as long as succeeding segment. Pedicel cup-shaped, yellowish brown to dark brown. Flagellum dark brown, flagellomeres elongate, basal flagellomere oval, remaining segments wider at base, tapering towards apex. Holotype flagellum 10 - segmented, but many specimens of both sexes have 11 - segmented flagellum. Apical flagellomere large, 1.6 × as long as preceding segment. Longest verticils nearly reaching length of respective flagellomeres. Rostrum testaceous yellow to pale greyish brown. Basal palpomeres pale, terminal segments dark brown. Labellum pale brown.

Thorax. Generally greyish yellow to brownish, densely covered with dense brownish grey pruinosity. Presutural scutum greyish yellow with yellow lateral margin, with three distinct dark brown stripes. Medial stripe darker than lateral, dark brown, wider frontally, not reaching suture caudally. Lateral stripe paler and more diffuse, extending from pseudosutural fovea frontally to suture caudally. Scutal lobe with diffuse dark area in the middle, lateral margin greyish yellow, area between scutal lobes obscure yellow. Scutellum weakly darkened. Mediotergite weakly darkened with more infuscate ventral margin. Pleuron obscure yellow with darkened ventral area of katepisternum, less visible in older museum specimens. Wing (Figs 54 View Figures 53–57 , 55 View Figures 53–57 ) long and narrow, nearly 4 × as long as wide, subhyaline, milky, with yellowish base, iridescent, without darker pattern, except indistinct pale brown stigma. Veins pale greyish brown, yellowish at wing base. Venation: Sc long, reaching far beyond branching point of R 2 + 3 + 4, nearly to the proximal margin of stigma. Cross-vein sc-r closer to base of Rs than to humeral vein. Rs 2.3 × as long as m-cu, nearly straight. Free end of R 1 as long as R 2. Vein R 2 transverse. Distal portions of R 3, R 4, and R 5 arched, tips of R 4 and R 5 converging. Stem of cell r 3 very short, shorter than r-m. Discal cell missing due to reduction of vein m-m. Cell m 1 short, its stem nearly 3 × as long as cell itself. Cross-vein m-cu approximately its own length beyond branching point of M. Vein CuP straight, A 1 slightly arched at distal part. Anal angle large, widely rounded. Halter pale with slightly darker brownish knob. Length of male halter 0.8 mm, of female 1.1 mm. Coxae brownish yellow. Trochanters yellow. Femora and tibiae pale brown, distal tarsomeres darker brown. Male femur I: 4.8 mm long, II: 5.6 mm, III: 5.3 mm, tibia I: 5.6 mm, II: 5.3 mm, III: 5.3 mm, tarsus I: 7.0 mm, II: 5.8 mm, III: 8.1 mm. Female femur I: 3.5 mm long, II: 4.0 mm, III: 3.7–5.6 mm, tibia I: 3.5 mm, II: 3.3 mm, III: 3.4–5.1 mm, tarsus I: 5.0 mm, II: 4.5 mm, III: 4.6–5.3 mm. Claw brownish yellow, without spines or teeth.

Abdomen. Brown to dark brown, covered with greyish pruinosity and sparse erect yellowish setae, basal sternites yellow in male, greyish brown in female. Pregenital segments concolourous with the rest of abdomen. Male terminalia (Fig. 56 View Figures 53–57 ) yellowish brown. Posterior margin of epandrium with low and wide slightly serrate median lobe covered with dense short but strong setae, lateral lobe long and narrow, finger shaped. Gonocoxite slightly longer than wider, with tuft of long dense setae mesally at base and few small spines at apex, without additional lobes. Interbase large, elongate blade extending beyond apex of gonocoxite, distal half widened, terminating in an acute spine, basal part narrower and finely serrate. Outer gonostylus elongate, fleshy and setose, oval with concave mesal surface. Inner gonostylus nearly as long as outer gonostylus, distal part subglobular, without setae. Aedeagus short. Ovipositor (Fig. 57 View Figures 53–57 ) yellow. Base of cercus narrowly dark brown, distal part pale yellow, raised upwards. Hypogynial valve nearly straight, yellow to pale yellow.

Elevation range.

From 200 m to nearly 2000 m.
