Eyes widely separated in both sexes, distance between them at base of antennae slightly less than length of scape. Antenna ( Fig. 5A ) 1.7-2.0 mm long in male, 1.8-2.5 mm in female, extending to wing base if bent backward. Both basal antennomeres dark brown, sparsely dusted with gray, scape elongate, nearly cylindrical, twice as long as pedicel, pedicel oval. Basal flagellomere yellow at base, 1.5 times as long as pedicel, remainder of flagellum brown to dark brown. Flagellomeres elongate, decreasing in length and width from the basal to the outermost. Apical segment nearly as long as preceding. Verticils dark brown, longest verticils 1.2 times as long as respective segments. Rostrum brown, dorsally dusted with gray. Palpus dark brown, mouth parts brown.

Thorax: Cervical sclerites brownish gray. Pronotum brown, dusted with gray pruinosity, narrowly yellowish brown frontally and posteriorly. Mesonotal prescutum grayish brown with two median dark brown stripes widely separated by gray area and less distinct lateral stripe. Tubercular pits very small and indistinct at frontal margin of sclerite, pseudosutural fovea brown, semi-polished. Scutal lobe brown, dense gray pruinose and with darker longitudinal spot closer to medial margin, area between lobes yellowish. Scutellum yellowish brown, dusted with gray. Mediotergite yellowish brown densely covered with gray pruinosity. Pleuron brown, densely covered with gray pruinosity, anepisternum slightly infuscated. Wing ( Fig. 5B, C ) iridescent, translucent, patternless with indistinct stigma. Veins brown, yellowish at wing base. Venation: Sc long, reaching wing margin slightly before branching point of Rs, sc-r slightly beyond tip of Sc. Rs medium-long, arched at base. Free end of R 1 short, oblique, R 2 twice its own length before the apex of R 1, far beyond branching point of R 2 + 3 and R 4. Cell r 3 nearly parallel-sided, just slightly widening towards wing margin, with long stem, which is approximately as long as discal cell. Cross-vein r-m distinct, at base of discal cell which is twice as long as wide. Position of cross-vein m-cu slightly varies from about at one-third to the middle of discal cell. Anal vein long, slightly sinuous, apex slightly before the level of Rs base. Anal angle widely rounded. Length of male halter 1.1-1.4 mm, of female 1.2-1.5 mm, stem yellowish with pale base, knob slightly infuscated. Coxae yellow, dusted with gray, forecoxa slightly darkened frontally.

Ninth segment of male dark brown ( Fig. 5D ), semi-polished, gonocoxite brownish-yellow. Ninth tergite wider than longer, posterior margin with deep median U-shaped incision and right-angled lateral lobe. Gonocoxite twice as long as wide, slightly narrower towards apex, without additional lobe. Outer gonostylus setose, elongate, arched, sclerotized towards apex, point-apexed. Inner gonostylus setose, long and narrow, blunt-apexed. Ninth sternite with tongue-shaped median lobe at posterior margin ( Fig. 5E ). Aedeagus long and narrow with V-shaped apex. Paramere dark brown spine-shaped. Ovipositor ( Fig. 5F ) dark brown at base, distal part of tenth tergite and postero-lateral area of eight sternite yellow.
