Redescription

Length: body 5 mm; wing 4.5 mm. Head (figs. 1 A, B): vertex carenate; ocellar triangle close to vertex, ocellar tubercle not well developed. Frons longer than wide, brownish; in profile convex; anterior part slightly conical, protruding over antennal base; hump arising from the ocellar region, shining brown, with two velvety black spots; anterior margin yellowish, slightly concave in dorsal view. Face slightly convex; dull, whitish yellow, with two small brown spots in upper ½; lower facial margin short. Eye oval, posteroventral outline concave, lower ½ strongly narrowed. Parafacial and gena narrow; parafacial yellow; gena brown anteriorly, whitish yellow posteriorly. Brown antenno­orbital spot between eye and antennal base. Mouthparts brownish yellow; palpus strongly slender, yellow. Antenna: yellow; scape shorter than pedicel; first flagellomere long, oval, with rather long dorsal pubescence; arista brown, long plumose above and below. Chaetotaxy: outer vertical seta 2 / 3 length of inner vertical seta, long; ocellar seta absent; postocellar setae short, cruciate; orbital setae reclinate, anterior seta 2 / 3 length of posterior seta, inserted closer to anterior frontal margin than to posterior seta; 2 strong genal setae; supravibrissal setae short.

Thorax: brown; mesonotum with paired wide, grayish vittae; proepisternum yellowish; pleurae grayish pruinose, brown, with yellowish dorsal longitudinal stripe; scutellum with yellowish apex; mesonotum strongly curved; scutellum flat. Chaetotaxy: dorsocentral setae arranged 0+ 2, posteriorly located, anterior seta smaller than posterior seta; 1 postpronotal seta; 2 notopleural setae; 1 prescutellar acrostichal seta; 8 rows of acrostichal setulae; intra­alar seta absent; 1 presutural and 1 postsutural supra­alar setae; 2 postalar setae; 1 proepisternal seta; 1 katepisternal seta; 1 anepisternal seta; anepimeron bare; 2 scutellar setae, apical pair slightly diverging. Legs: mostly yellow; fore tibia and fore tarsus whitish; tibiae with sub­basal and apical brown rings; apices of tarsi darker. Chaetotaxy: fore coxa with 1 preapical dorsal seta, 2 apical dorsal setae; fore femur with posterior row of setae; fore tibia with 1 short preapical dorsal seta; mid coxa with apical row of setae; mid femur with anterodorsal row of setae and 1 short apical posteroventral seta; mid tibia with 1 preapical anterodorsal seta, 1 strong apical ventral seta and many apical strong setulae; hind coxa with 1 posterior seta and 1 apical dorsal seta; hind femur with 1 subapical anterodorsal seta, and anterior, anterodorsal and posterodorsal preapical setae; hind tibia with 1 short preapical seta. Wing (fig. 1 C): brown, with many paler spots and narrow apical band; veins brown; costa sapromyziform; R bare; crossvein r­m beyond middle of discal cell; crossvein dm­cu in median 1 / 3 of r 4 + 5; longitudinal veins almost parallel; anal vein shorter than length cell cup. Halter destroyed in the holotype.

Abdomen: brown; holotype with just the first five tergites, other parts destroyed.
