Redescription. Male. Body length 5.5–6.0 mm. Head ( Figs. 5 B, C, D): Eye bare, facet slightly expanded on anterior margin in median part; frons broad on vertex, becoming narrow anteriorly, median part about 0.33–0.35 times of head-width; frontal vitta, frontal triangle and frontal-orbital plate without obvious boundary; frons, face, gena and antenna with silvery pollinosity; upper orbital setae 2, frontal setae 2 and with 1 row of short setae on outer part; parafacial bare, about as wide as postpedicel; facial ridge low, slightly concave; antenna dark brown, postpedicel about 2.8–3.0 times as long as broad (2.2–2.4 times as long as pedicel), arista plumose, the longest setula equal to width of postpedicel; face planate, without facial carina; epistoma not projecting to vibrissal angle; vibrissa weak, shorter than length of distance between them; genal height about 1/5 of eye height; postocular setae 3 rows, posteriormost 1 row situated in occiput; postgena with black setulae; proboscis short, labella small, with 2 prestomal teeth on posterior margin, prementum shinning; palpi yellowish, compressed, expanded in distal part, spoon-shaped apically, apical inner surface setulose and outer surface bare.

Thorax: Ground color black with dense silver grey pollinosity; scutellum with brown pollinosity; acr 0+1 (thin); presutural 5 or 6 rows of acrostichal setulae; dc 2+3; ia 0+2, without pra; basal and apical scutellar setae all developed; scutellum bare on lateral surfaces and underneath; notopleuron bare; median part of anepimeron with numerous bristles; prosternum, meron and katepimeron bare; spiracles brown, posterior one small and with 4 or 5 setae on posterior lower margin; katepisternal setae 1+2.

Wings: Slightly hyaline; veins of wing becoming brown apically; tegula and basicosta dark brown; subcostal sclerite yellow; costal spine about as long as crossvein r–m; vein C with ventral setulae; other veins bare; vein R4+5, M and crossvein dm-cu straight; calypteres yellowish; halteres dark brown; WIPs with 3 clearly demarcated color bands (green, blue and magenta) evenly distributed at posterior part of the wing ( Figs. 31 A, B).

Legs: Black except distal 1/5 of fore tibia and knees yellow, with dense silver grey pollinosity; fore tibia without p seta; mid femur with 1 pv row which elongated on basal part, with 1 or 2 preapical pd; mid tibia without ad, with 1 strong preapical d and 1 median p; hind femur with 1 submedian av and 2 or 3 elongated pv in basal l/3; hind tibia with 1 submedian av, 1 ad and 1 preapical d; first hind tarsomere swollen and shortened ( Figs. 1 A; 30A), with dense and long setulae ventrally, elongate to the basal half of second hind tarsomere, with a smoothly bare ventral surface on basal part ( Fig. 30 B), shorter than summed length of other tarsomeres; tarsi shorter than tibia, claws and pulvilli small.

Abdomen: ( Fig. 5 E) Ground color black, oval, with grey pollinosity; syntergite 1+2 black, tergites 3 and 4 dusted with large triangular lateral black patch on each side, tergite 5 with pair of large black patches on anterior margin.

Female. Body length 7.0– 7.4 mm. General characters as in male but differing from male in: frons about 0.36– 0.38 times of head-width at median part; frons, face, gena and antenna with brown pollinosity ( Figs. 7 B, C); palpi brown; thorax with brown pollinosity; WIPs with 4 color bands (green, blue, magenta and yellow) at posterior part of the wing, of which green band larger and yellow band narrower; hind femur with 4 or 5 strong pv in basal 1/2; first hind tarsomere not swollen; tergite 5 with brownish yellow pollinosity, without patches.
