Diagnosis. A medium-sized fly averaging 10.6 mm (10–11/5) in length. Stem vein setose dorsally; wing yellowish along costa; subcostal sclerite bare; facial ridge with short row of dark brown supravibrissal setae at base. Male frons narrow, 0.01 of head width at narrowest; epandrium, cerci and surstyli as in Figs 79–80 View FIGURES 75–80 . Female T6 of WV shape ( Fig. 314 View FIGURES 312–317 ).

Redescription. Male. Head. Frons narrow, 0.016 (0.01–0.02/5) of head width at narrowest. Fronto-orbital, parafacial, gena and postgena golden when viewed from above, orange when viewed from below; frontal vitta orange when viewed from above, with golden streaks when viewed from below; fronto-orbital broader below, narrowing to thin line at about 1/3 of its length, frontal vitta obliterated; gena and lower parafacial with horizontal row of stout dark setae; antenna pale yellow; occiput with heavy whitish tomentum and fine, pale setae; median occipital sclerite shiny dark orange; eye with median facets about 4x size of lateral facets; ocellar triangle small, anterior ocellus slightly larger than posterior ocelli; facial ridge with few short, stout, dark brown supravibrissal setae at base.

Thorax orange-brown with whitish tomentose stripes; pleural area orange with whitish tomentum; chaetotaxy: with ac 2:2, dc 2:3, ia 1, ph 1, ppn 3x 3, kat variable 1:1 or 1:2, meral setae typical, 1 pair converging ap, 1 sa, 1 lat, 1 stout bas, 1 weak pb, 1 disc; subscutellum prominently developed; spiracles yellow, medium-sized; legs entirely orange. Wing with anterior edge along costa and veins faintly yellowed, area around crossvein r-m with dark macula; subcostal sclerite orange with dense pubescence; basicosta and tegula orange; stem vein with row of fine, tan setae above; section IV 0.56 of section III; upper calypter pale with dark rim and tan setae; lower calypter tan disc and pale rim with fringe of long pale setae.

T1+2 and T3 each with two pairs of small lateral marginal setae; T4 with posterior row of stout setae, disc of T5 only with sparse, scattered, short to medium-long, fine setae. Terminalia in lateral view with surstylus curved slightly backward, cercus with apical hook ( Fig. 79 View FIGURES 75–80 ); in posterior view cerci with narrow base, broader midway then tapered to blunt tip ( Fig. 80 View FIGURES 75–80 ); phallus in lateral view with medium-long, stout epiphallus with slight backward curve ( Fig. 169 View FIGURES 163–172 ); broad in dorsal view, with circular hypophallic lobes and an apical fork on acrophallus ( Fig. 170 View FIGURES 163–172 ); T6, STS7+8, pre- and postgonite, ejaculatory sclerite and ST6 as in Fig. 227 View FIGURES 222–228 ; ST1–5: ST3–4 narrowed, as in Fig. 270 View FIGURES 266–279 .

Female. Similar to male except frons 0.246 (0.24–0.26/5) of head width at narrowest. T6 of FU shape, nearly flat; T7 with wide and deep indentation on anterior edge; T8 as pair of sclerites ( Fig. 314 View FIGURES 312–317 ); ST6–8 and hypoproct as in Fig. 358 View FIGURES 350–369 ; spermathecae filiform ( Fig. 399 View FIGURES 370–400 ); ST1–5 as in Fig. 443 View FIGURES 439–453 .
