Diagnosis. A large fly averaging 12.6 mm (12–13/5) in length. Postpronotal setae 2x 2; wing with base yellowish and anterior margin infuscated from costa to vein R 2+3; T3–4 concolorous, without distinct posterior bands; posterior row of stout marginal setae on T4; posthumeral seta absent.
Redescription. Male. Head. Frons broad, 0.108 (0.10–0.12) of head width at narrowest, about equal to width of parafacial at level of lunule. Fronto-orbital broad, pale orange when viewed from below and yellowish when viewed from above with faint yellowish tomentum, sclerites almost touching midway; frontal setae ascending about 60% of distance to vertex; frontal vitta dark orange, broad below, narrowed, almost obliterated midway but broader above, ascending to base of ocellar triangle; parafacial pale orange; gena orange with silvery tomentum, horizontal row of stout, dark setae midway, and scattered dark setae except for a few pale setae near posterior margin; postgena orange with silvery tomentum and fine golden setae; occiput dark with silvery tomentum and fine golden setae, median occipital sclerite shiny dark brown; antenna: pedicel, first flagellomere and base of arista orange, setae on arista brown; palpus typical; eye with median facets 2x size of lateral facets; ocellar triangle moderate, anterior ocellus slightly larger than posterior ocelli; supravibrissal setae short and dark, ascending about 1/6 of distance to antennal base.
Thorax. Dorsum dark brown to black with 4 pale tomentose stripes; pleura orange; chaetotaxy: ac 0:1, dc most 2:3, some 3:3, ia 0, ph 0, ppn 2x 2, kat 1:1, meral setae typical, 1 pair parallel or slightly diverging ap, sa and lat absent, 1 stout bas, 1 weak pb, 1 disc; subscutellum moderately developed; spiracles medium-sized, pale orange; legs orange except mid and hind tibiae and tarsi brown. Wing yellowish with anterior edge infuscated from costa to about midway between veins R 2+3 and R 4+5; subcostal sclerite orange and bare; basicosta and tegula orange; section IV 0.21 of section III; discs of upper and lower calypters pale orange; rims of upper and lower calypters pale, both with long orange setae.
Abdomen. T1+2 orange, T3 sometimes with anterior edge orange, remaining portions of T3–5 shiny metallic blue, usually only T1+2–3 with whitish tomentum; T1+2–3 with dorsolateral marginal setae, posterior margin of T4 with row of stout setae; disc of T5 with fairly dense, medium-long setae only. Terminalia in lateral view with surstylus weakly curved backward ( Fig. 83 View FIGURES 81–86 ); in posterior view, cerci with broad base tapered distally to rounded tips ( Fig. 84 View FIGURES 81–86 ); phallus in lateral view with epiphallus of moderate length and curvature ( Fig. 173 View FIGURES 173–182 ); in dorsal view, hypophallic lobes expanded posteriorly ( Fig. 174 View FIGURES 173–182 ). T6, STS7+8, pre- and postgonite, ST6 and hypandrium as in Fig. 229 View FIGURES 229–235 ; ST1–5 very narrow, as in Fig. 272 View FIGURES 266–279 .
Female. Similar to male except frons 0.274 (0.24–0.29/5) of head width at narrowest. T6 of WU in shape; T7 with suture midway; T8 as two sclerites, epiphallus bilobed ( Fig. 316 View FIGURES 312–317 ); ST6–8 and hypoproct as in Fig. 360 View FIGURES 350–369 ; spermathecae filiform ( Fig. 401 View FIGURES 401–410 ); ST2–5 as in Fig. 445 View FIGURES 439–453 .

Distribution. Bolivia, Brazil, Guyana, Peru, Venezuela. Guimar„es (1977) lists French Guiana. Marinho et al. (2017) also listed it from Colombia and Ecuador.
Remarks. Five specimens from Bolivia ( TLW 280), Brazil ( TLW 278–279) and Peru ( TLW 276–277) were barcoded, and three GenBank sequences from Brazil ( JQ 246687 View Materials , KR820730 View Materials , KR820731 View Materials ) were added to the analysis. They formed a distinct group with some genetic variation between sequences. The genetic distance between sequences within Brazil was less than 2%, whereas between Brazil and Bolivia, it was 2.3% and between Brazil and Peru it was around 3.5% ( Fig. 488 View FIGURE 488 ). Morphologically, all these variants appear very similar, and further molecular and morphological studies are needed to determine if any cryptic species can be found within them.
