Description of male. Body length: 4.25 mm (n=2), wing length: 3.0 mm (n=2). Differs from the female by the following: head with frons width at vertex 0.29 of head width; antenna with first flagellomere multifissicorn; antenna with scape, pedicel and inner rami of flagellomere yellow, and the extreme base of arista and the outer rami of flagellomere brown, arista brownish; gena about one-sixth of eye height; proboscis black-setulose on prementum and golden-setulose on labella. Length of median lateral scutellar seta varying in length from slightly longer than 2/3 (specimens from Amazonas) to about 4/5 (specimen from Colombia) length of posterior lateral scutellar seta.

Terminalia (Figs 2–4): Very similar to those of B. brasiliana when compared with the illustration of terminalia given by Arnaud (1963), differing by the cerci and surstylus broader and the first strongly curved dorsally at midlength in lateral view. Surstylus in posterior view with basal halves broader.

Comments: Female described by Arnaud (1963), with the wing illustrated (fig. 11). The males herein described were compared with the female description given by Arnaud (1963). The illustrated terminalia was dissected from a male from Manaus (Amazonia, Brazil), and the photographed male is also from Manaus. The specimens examined here showed variation in the length of median lateral scutellar seta. The female holotype from Peru has the pair of median lateral scutellar setae “more than fourfifths of length of apical [posterior] lateral scutellar bristles” ( Arnaud 1963), as well as the Colombian male and female here examined, but this length differs from that found in males from Amazonas, which have the median lateral scutellar seta slightly longer than 2/3 length of posterior lateral one.

Distribution: COLOMBIA (Putumayo) rec. n., PERU (Huánuco), BRAZIL (Amazonas) rec. n.
