Diagnosis. A fairly large fly averaging 11.4 mm (11–12/5) in length. Postpronotal lobe with 2x 2 setae; wing hyaline with only faint yellowing along costa; thorax orange-brown with pale tomentose stripes; abdomen shiny blue; ac 0:1.

Redescription. Male. Head. Frons 0.06 (0.05–0.07/5) of head width at narrowest. Fronto-orbital orange below, silvery above; frontal setae ascending about 40% of distance to vertex; frontal vitta orange, obliterated about midway above; parafacial silvery; gena pale yellow with silvery tomentum; postgena yellow with silvery tomentum and silky yellow setae; occiput shiny dark brown dorsolaterally, remainder pale yellow with fine yellow setae; median occipital sclerite shiny dark brown; pedicel, first flagellomere and arista yellow-orange; palpus typical; eye with median facets about 2x size of lateral facets; ocellar triangle medium-sized, diameter of anterior ocellus about twice that of posterior ocelli; supravibrissal setae limited to small cluster near base of facial ridge.

Thorax. Dorsum dark orange-brown with four pale orange tomentose stripes; pleura orange; chaetotaxy: ac 0:1, dc 2:3, ia 0, ph 0, ppn 2x 2, kat 1:1, meral setae fine, tan, in shape of inverted L, horizontal portion very short, 1 pair of parallel ap, sa and lat absent, 1 bas, 1 weak pb, 1 disc; subscutellum moderately developed; spiracles small and orange; legs: trochanters and femora orange, tibiae and tarsi brown, darker on fore leg. Wing hyaline with faint yellowing along costa, whole wing somewhat yellowish; subcostal sclerite yellow and bare; basicosta yellow, tegula orange; section IV 0.16 of section III; disc of upper calypter pale, rim dark with short pale-yellow setae; disc of lower calypter golden, rim yellow with long golden setae.

Abdomen. T1+2 orange, T3 orange with small forward-pointing arrow-like dark area mid-dorsally [good specimens]; T4 mostly metallic blue-black with some orange color laterally and a pair of lateral marginal setae; T5 shiny blue-black, disc with dense, medium-long fine setae only. Terminalia in lateral view with surstylus moderately curved backward, cercus with apical hook ( Fig. 61 View FIGURES 57–62 ); posterior view as in Fig. 62 View FIGURES 57–62 ; phallus in lateral view with short, slightly curved epiphallus ( Fig. 151 View FIGURES 145–152 ); in dorsal view, hypophallic lobes narrow ( Fig. 152 View FIGURES 145–152 ); T6, STS7+8, pre- and postgonite, ST6 and ejaculatory sclerite as in Fig. 218 View FIGURES 216–221 ; ST1–5 narrowed, as in Fig. 261 View FIGURES 252–265 .

Female. Similar to male except frons 0.274 (0.26–0.28/5) of head width at narrowest. T6 of WV shape, T7 continuous, weakened midway, T8 as separate sclerites ( Fig. 305 View FIGURES 300–305 ).
