This species is easily recognized by having dorsocentral setae 2 + 3; vein R 1 with conspicuous setulae on median half dorsal surface; Rs node and base of vein R 4+5 setulose dorsally. Redescription. Male . Length: Body: 7.6 mm , Wing: 5.76 mm . Color. Face silver pollinose. Antenna and arista dark brown. Palpus dark brown. Calypters uniformly yellowish. Halter yellow. Wing hyaline yellowish with brown cloudy spots at the costal margin at apex of vein R 2+3 . Presutural scutum dark brown with 2 spots near scutum; humeral callus and notopleura gray pollinose; scutum dark brown with 2 spots near scutellum that coincide with third postsutural dorsocentral seta; scutellum dark brown. Pleurae dark brown with katepisternum mostly gray pollinose. Legs dark brown. Abdomen with median longitudinal silver vittae on all tergites and dark brown with silver lateral round areas on all tergites. Head: Holoptic, distance between eyes about 0.08 times head width, eye finely and sparsely ciliated. Inner and outer vertical setae as long as, but somewhat finer than, ocellar seta; frontal setae in 7 pairs; 1 proclinate orbital seta. Ocellar setae long; ocellar triangle with a tuft of hairs. Flagellomere I about 2 times pedicel length, ending before insertion of vibrissa. Arista with hairs shorter than diameter of the arista at base. Parafacial and fronto-orbital plate bare. Palpus filiform, not dilated apically. Thorax. Chaetotaxy. Acrostichals 0 + 1; dorsocentrals 2 + 3, all setae developed and of same length; intra-alars 2 + 1; supra-alars 2; basal postpronotals 2; notopleurals 2; postsupra-alars 2. Scutellum with 2 long setae basal and apical. Anepisternum with six long setae; katepisternal 1 + 2. Prosternum setulose. Legs. Fore femur with a complete row of posterodorsal and posteroventral setae; fore tibia with 2 apical setae (dorsal and anteroventral). Mid femur on ventral surface with 6 strong setae on basal half; posterior surface with 2 pre-apical setae; mid tibia with 1 median seta on posterior surface and 3 apical setae (anteroventral, ventral and posteroventral). Hind femur with complete row of setae on anterodorsal and anteroventral surface with 4 setae on apical half. Hind tibia with 2 median setae on anterodorsal and anteroventral surfaces; 2 apical setae (anterodorsal and anteroventral). Wing.Vein R 1 with conspicuous setulae on median half of dorsal surface; Rs node and base of vein R 4+5 setulose dorsally and ventrally, vein dm-cu slightly sinuous, apical portion of vein M bent toward vein R 4+5 . Abdomen . Tergite III with a row of setae on margin; tergite IV with 1 pair of discal setae; tergite V with a row of setae on margin and 1 pair of discal setae.Sternite 1 bare; sternite 5 trapezoid, longer than wide, with many setae and two apically developed ( Fig. 1 ). Terminalia. Cercal plate longer than wide, with submedian fusion, apex with long setae on inner margin; surstylus similar in length as cercal plate ( Fig. 2 ). Distiphallus long, about 2.5 times the length of pregonite; postgonite straight and shorter than epiphallus ( Fig. 3 ). Female . Length: body 6.96 mm ; wing 6.32 mm . Similar to male, but dichoptic, distance between eyes 0.36 head width. Frontal seta in 5 pairs, 2 reclinate orbital setae; inner vertical setae convergent; outer vertical setae divergent.Fronto-orbital plate with few setulae.
