Differs from congeners in the combination of slightly brown microtomentose mesonotum, black tibiae and silvery microtomentose T2-5 with subshiny black tip.
Male coloration and vestiture: frons subshiny black, ocellar triangle and upper orbital plates shiny black, lunule black, basoflagellomere black, face brown microtomentose, palpus black; thorax with mesonotum slightly brown microtomentose, scutellum and pleura same except for shiny spots on an- and katepisternum, wing hyaline, veins light brown, brown spot at tip of vein R1 absent, calypter hyaline with light brown margin, halter black, legs black except for yellow basitarsi; abdomen with T2-5 silvery microtomentose, except for subshiny tip of T5.
Morphology. Head: frons with 2+0.4 orbital and 2 frontal setae, anterior frontal seta medioclinate. In males frons 2.3x as wide at posterior margin than at base of antenna, arista about 3.8x as long as basoflagellomere wide, pubescence on arista very short, posterior eye margin with slight notch (3oc) and very slight emargination (1oc).
Thorax: 2 dc, 1 prsc, 1 pprn, 1 prs, 1+0.7 keps setae, posterior prsc about as long as posterior dc, seta between posterior prsc and posterior dc small. Wing with vein R4+5 and M1 converging (3.0), and ultimate section of vein M1 2.6x as long as penultimate section. Fore femur normal setulose, tibial organ absent.
Male abdomen: posteromedial triangular projection of T1 into T2 present. Tergal chaetotaxy: T2 anterolateral corner with single line of setae, T2-5 posterior margin with one row of setulae, the ones on T5 long. S5 1.3x as long as wide, 1.9x as long and 2.8x as wide as S4, setulose in middle, posterior margin indented. Male genitalia with apical seta on cercus longer than epandrial setae, 1 seta on subepandrial plate, surstylus 0.4x as long as epandrium high, dilated posteroapically (1.3x), 1.4x as long as wide, structure of lateral surface smooth, medial surface without setulae.
Special characters: palpus with some long setae ventrally..
Body length: 2.5 mm; wing length: 2.0 mm.
