 Diagnosis. Body coloration dark brown (Figs 28A, B). Posterior margin of pronotum with shallow arched indentation (Fig. 28D). Forewing dark brown, with yellowbrown veins (Fig. 28A). Ventral margin of periandrium with triangular apex (Fig. 29). Gonapophysis VIII (first valvula) with two projections on lateromedian margin (Fig. 30E).   
 Description. Measurements. Body length: male 3.8 – 4.1 mm (5.5 – 7.1 mm including wings) (N=3); female: 3.7 – 4.0 mm (6.7 – 7.0 mm including wings) (N=3).   
 Coloration. General body color dark brown (Figs 28 A, B). Clypeus, lower half of the gena and episternum light brown; region around the compound eye, lateral carinae of the frons above compound eye, apex of pedicel and pedicel plaque organs, pustules of pronotum, median and lateral carinae of pronotum, posterior median and lateral carinae of the mesonotum, diffuse stripe in the latero-anterior region of the mesonotum, anterior pronotum border and rounded spot in the anterior region of the tegula pale yellow; epimeron white. Forewing dark brown, semihyaline, with white regions and yellow brown veins: narrow white stripe covering ir cross-vein; narrow white stripe extending from r-m2 cross-vein to the MP 4 vein base; white x-shaped region covering the m-cu 2 cross-vein, median region of the CuA1 vein and the icua cross-vein; narrow white stripe near at apex of CuA 2; narrow white stripe covering icu cross-vein; apex of clavus white (Fig. 41C). Hind wing semihyaline, dark brown with hyaline regions (Fig. 41D). Legs light brown. Abdomen dark brown, except white diffuse spot on tergites V and VI, sternites III, IV + V; anal tube (segment X) and gonostyli light brown (Fig. 28A).   
 Head: frons narrow, distance between the lateral carinae of frons on median portion, approximately 3 times smaller than maximum width of vertex (Fig. 28C). Clypeus approximately 2.5 times longer than its maximum width; median carina of clypeus strongly marked, almost touching epistomal suture (Fig. 28C). Pedicel oblong, approximately 3 times longer than the scapus (Fig. 38D). Scape short with cuticular denticles (Fig. 38D).   
 Thorax: anterior margin of pronotum with tapered apex, lateral longitudinal carinae of pronotum converging at an angle anteriorly and subparallel to each other towards posterior margin; median longitudinal carina of pronotum present, strongly marked; posterior margin of pronotum with shallow arched indentation in the middle; pronotum with pustules on posterior margin (Fig. 28D); median and lateral longitudinal carinae of mesonotum present, strongly marked (Fig. 28D).   
 Forewing: RA vein with the apex gently curved anteriorly; RP vein with the apex strongly curved anteriorly; r-m cross-vein present; ir cross-vein distant from r-m2 cross-vein; MP vein with five branches with apex gently curved anteriorly; first bifurcation of MP vein arising after r-m cross-vein; m-cu cross-vein present; CuP vein approximately 2.5 times longer than Pcu + A 1 vein; apex of clavus with straight angle (Figs 41C).   
 Hind wing: first bifurcation of MP vein arising before m-cu cross-vein (Fig. 41D).   
 Legs: metatibia with 7 apical spines; metatarsus with 7+6 apical spines.   
 Abdomen: posterior pit of the sternite III rounded (Fig. 28E); posterior half sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternite VII rounded. Female (Fig. 28B). Similar to the male, except sternite VI partially covering by the sternite VII, anal tube (segment X), yellowish brown.   
 Male terminalia (Figs 29A–G). Pygofer with posterior margin without projections, with few setae in posterior view (Fig. 29B). Gonostyli with truncated apex in lateral view, outer margin with short and pointed projection near the apex, inner margins with some setae (Figs 29A, D, E). Phallic complex (Figs 29F, G): periandrium robust; dorsal and ventral margin of periandrium with triangular apex (Fig. 29G). Inner sclerotised plates narrowing towards the apex, with surface with small spiniform projections (Figs 29F, G). Anal tube (segment X), short, apex smoothly reentrant in dorsal view, with few sparse setae dorsally (Fig. 29C).   
 Female terminalia (Figs 30A–E). Pygofer with numerous setae and small spiniform projections in posterior view (Fig. 30B). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with small spiniform projections in the middle in lateral view; two lateroapical projections of unequal sizes, with smooth dorsal margin in lateral view (Fig. 30E). Bursa copulatrix sparsely filamentous apically, obtuse apex, small setae on apical third and small spiniform projections on median region in lateral view (Fig. 30E). Gonapophysis IX (second valvula) robust, forked about on apical half, lobes with pointed apex, strongly curved latero-ventrally, hook-like in dorsal view (Fig. 30D). Gonoplac (third valvula) subtrapezoidal, apex semi-rounded with numerous apical setae and sparse setae laterally (Fig. 30C). Anal tube (segment X), short, apex smoothly reentrant, with few sparse setae in dorsal view (Fig. 30A).   
 Variations. Reddish spots have been observed on sternites V, VI and VII, in some specimens.   
 Distribution. Brazil (Acre, Amazonas) and Ecuador (Felton) (Fig. 44).   
 Comments. B. pulla Muir, 1934 differs from B. pennyi sp nov. as previously discussed in the description of the latter.
