Diagnosis. A large, dark fly averaging 13.4 mm (12–15/5) in length. Postpronotal lobe with 3x 3 setae; wing with dark infuscation along anterior margin; dorsum of abdomen without tomentose pits; supravibrissal setae orange, ascending about 1/3 of distance to antennal base; legs: orange except tibiae and tarsi tan to dark brown; subcostal sclerite with stout reddish setae; section IV of wing 0.82 of section III. Epandrium, cerci and surstyli as in Figs 71–72 View FIGURES 69–74 . Female terminalia as in Fig. 310 View FIGURES 306–311 .

Redescription. Male. Frons narrow, 0.013 (0.01–0.02/5) of head width at narrowest, about half the width of anterior ocellus. Most of head pale gold, including fronto-orbital, frontal vitta, parafacial, gena, postgena occiput and antenna; fronto-orbitals very slender, obliterating frontal vitta in upper half, frontal setae ascending halfway to vertex; gena with pale yellow tomentum and row of stout brown setae extending horizontally across parafacial to vibrissa, otherwise with scattering of tan setae; postgena with pale yellow tomentum, anterior 1/3 with tan setae, posterior 2/3 with golden setae; occiput with pale tomentum and golden setae, median occipital sclerite shiny orange; antenna entirely gold with pale tomentum, arista tan; palpus typical; eye with median facets about 3x size of lateral facets; ocellar triangle small, with ocelli about equal in size; supravibrissal setae bright orange, ascending about 1/3 of distance to antennal base.

Thorax. Dorsum dark orange with faint golden tomentose stripes; pleura orange with golden tomentum; chaetotaxy: ac 2:1, dc 2:3, ia 1, ph 1, ppn 3x 3, kat 2:1, meral setae tan, very fine, otherwise typical, 1 slightly converging pair ap, sa absent, 1 very weak lat, 1 stout bas, 1 weak pb, 1 disc; subscutellum moderately developed; spiracles orange, medium-sized; legs: femora orange, tibiae and tarsi tan to dark brown. Wing with broad infuscated area on anterior margin from costa to R 4+5; subcostal sclerite with stout reddish setae; basicosta dark orange, tegula bright orange; section IV of wing 0.82 of section III; discs of upper and lower calypters pale orange-brown; rim of upper calypter dark with short dark setae, rim of lower calypter pale with long pale orange setae.

Abdomen. T1+2 yellow-orange; T3–5 shiny brown to blue or purple, anterior 2/3 of T3 with whitish tomentum, remainder of T3 and all of T4–5 shiny dark blue; T4 with pair of posterolateral marginal setae, T5 with row of small marginal setae, disc of T5 with dense, long, fine setae only. Terminalia in lateral view with surstylus curved backward, cercus straight, ending in apical hook ( Fig. 71 View FIGURES 69–74 ); in posterior view, base of cerci broad, evenly tapered to blunt tip ( Fig. 72 View FIGURES 69–74 ); phallus in lateral view with epiphallus short and almost straight ( Fig. 161 View FIGURES 153–162 ); in dorsal view, hypophallic lobes very broad, pear-shaped, fine serrations ( Fig. 162 View FIGURES 153–162 ). T6, STS7+8, pre- and postgonite, ejaculatory sclerite, ST6 and hypandrium as in Fig. 223 View FIGURES 222–228 ; sternites broad, uninform in width, as in Fig. 266 View FIGURES 266–279 .

Female. Similar to male except frons 0.29 (0.28–0.30/5) of head width at narrowest. T6 of WU shape, with pos- terior incision midway; T7 continuous, weakened midway; T8 as separate sclerites ( Fig. 310 View FIGURES 306–311 ); ST6–8 and hypoproct as in Fig. 354 View FIGURES 350–369 ; spermathecae filiform ( Fig. 395 View FIGURES 370–400 ); ST1–5 as in Fig. 439 View FIGURES 439–453 .
