Wing length (n=10): 8.7–12.1 mm . Redescription . MALE ( Fig. 1 ). Head . Eye bare; holoptic, touching for at least 4 times length of ocellar triangle, facets enlarged in dorsal half. Frons shining black; with black-brown pollinosity; dispersed pilosity of short pale pile, along dorsal margin longer black pile; rugose area shining black, occupying half of entire width and at least three-fourths of height of frons. Face shining black; with greyish pollinosity dorsally and ventrally of facial tubercle; dispersed pilosity of short pale pile; facial tubercle elongated, moderately pronounced. Three tiny silvery maculae present along inner margin of eye. Occiput dorsal third shining black; ventral two-thirds with conspicuous silvery pollinosity, ventrally with dispersed pale pile. Antennal segments black to black-brown; arista yellow-brown, in basal half with long pile equal to width of pedicel. Thorax . Scutum and scutellum mainly shining black, at most with weakly developed black-brown pollinosity. Devoid of pilosity except for tiny dark pile which are hardly visible, along anterior margin slightly longer; lateral margins dorsally of anepisternum with long black pile.
