Thorax: Ground color black with dense silvery grey pollinosity; acr 0+1 (trichoid), presutural 7–8 rows of acrostichal setulae; dc 0+1; ia 0+2; without pra; basal and apical scutellar setae all developed; scutellum bare on lateral surfaces and underneath; notopleuron bare; anepimeron with numerous bristles; prosternum, meron and katepimeron bare; anterior spiracle yellow, posterior spiracle brown and small and with 2 or 3 setae on posterior lower margin; katepisternal setae 1+2.

Wings: Brown; slightly hyaline; veins becoming brown apically; tegula, basicosta and subcostal sclerite brownish yellow; costal spine slightly shorter than vein r-m; vein C with ventral setulae; other veins bare; vein R4+5, M and crossvein dm-cu straight; calypteres yellowish white; haltere yellow; cell r2+3 with dark cloud; WIPs with 4 demarcated bands (blue, magenta, yellow and cyan), of which blue band large and cyan band narrow ( Figs. 31 M, N).

Legs: Black except basal femur; distal 1/4 of fore tibia, mid and hind tarsi and knees yellow; fore tibia with 1 submedian p; mid femur with 1 row of lodging pv; mid tibia with 1 submedian p; hind femur with short av and pv rows; hind tibia with 1 preapical av, 1 preapical ad and ad rows; first hind tarsomere dictinctly shortened and swollen, ( Fig. 1 J), swollen part elongated to basal half of second hind tarsomere and with tuft; second hind tarsomere compressed, median part ridgy and jubate from posterior view; tarsi shorter than tibiae; claws and pulvilli small.

Abdomen: Ground color black; oval; with dense grey pollinosity; tergites 1–3 with light black patches in the middle, tergite 4 with a large triangular lateral brown patches, tergite 5 dusted with brown patches on posterior margin ( Fig. 27 F), 1/2 apex of tergite 5 with brown patches.

Female. Body length 5.4–5.6 mm. General characters as in male but differing from male in: genal height about 1/4 of eye height; wing without cloud; first hind tarsomere not swollen; tergites 3 and 4 with median stripe ( Fig. 29 D).

Distribution. China (Guangdong, Liaoning), Japan, South Korea.
