Differs from congeners in the combination of subshiny black ocellar triangle, 4 dc, black tibiae, and silvery microtomentose male T2-5.
Male coloration and vestiture: frons subshiny black, ocellar triangle and orbital plates subshiny, lunule black, basoflagellomere black, face greyish microtomentose, palpus black; thorax with mesonotum brown microtomentose, scutellum brown microtomentose (densely when viewed from anterior, otherwise weakly), pleura same, wing hyaline, veins brown, brown spot at tip of vein R1 weak, calypter light brown with brown margin, halter black, legs black except for brown tarsi, fore and hind tarsus with yellow brush; abdomen with T2-5 silvery microtomentose.
Morphology. Head: frons with 2 orbital and 2+0.5 frontal setae, middle frontal seta slightly medioreclinate. In males frons 2.8x as wide at posterior margin than at base of antenna, arista about 4.0x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with wide notch (6-7oc) and emargination (2oc).
Thorax: 3+1 dc, 3+1 prsc, 2 pprn, 1+2 prs, 2+0.6 keps setae, posterior prsc about as long as posterior dc, seta between posterior prsc and posterior dc present. Wing with vein R4+5 and M1 converging (2.6), and ultimate section of vein M1 1.5x as long as penultimate section. Fore femur strongly setulose, tibial organ absent.
Male abdomen: posteromedial triangular projection of T1 into T2 present. Tergal chaetotaxy: T2 anterolateral corner with more than 3 lines of setae, T2 posterior margins with 3-4 rows of setulae, T3-4 with 2 rows, tip of T5 with long setae. S5 1.2x as long as wide, 1.9x as long and 3.3x as wide as S4, setulose on posterior 3/4, heart-shaped. Male genitalia with apical seta on cercus longer than epandrial setae, 1 seta on subepandrial plate, surstylus 0.8x as long as epandrium high, bent posteriorly, dilated apically (1.4x), 2.5x as long as wide, structure of lateral surface smooth, medial surface with 3-5 setulae along anterior margin moving medially basally.
Special characters: nearly no setulae directly anterior to prsc and posterior dc.
Body length: 3.2 mm; wing length: 2.9 mm.
