Condition of the material examined: Wings with broken apex; legs broken and lost.

Additional material examined: BRASIL, Amazonas, Manaus, Reserva Ducke, Rod [ovia] 010, Km 26, 14.ii a 6.iii.2007, Malaise, Dossel, Platô, L / O, G. Freitas & M. Feitosa cols. (1 ♂, INPA) ; Pará, Conceição do Araguaia , 16– 17.xi.1983, CDC , J. R. Arias eq[uipe] cols (7 ♂, 3 ♀, INPA) ; idem 19–31.i.1983, CDC: 1m (1 ♂, INPA) . PANAMÁ, Canal Zone : Barro Colorado, 13.vii.1924, N. Banks (examined by photography) (1 ♀, NHM) .

Diagnosis. Body coloration dark yellow ( Fig. 4A, B View FIGURE 4 ). Frons narrow ( Fig. 4C View FIGURE 4 ). Posterior margin of pronotum almost straight ( Fig. 4D View FIGURE 4 ). Dorsal margin of periandrium with shallow indentation ( Fig. 5G View FIGURE 5 ). Gonapophysis VIII (first valvula) with four projections on lateroapical margin and dorsal margin smooth ( Fig. 6E View FIGURE 6 ).

Redescription (male and female). Measurements. Body length: male 2.5 – 2.7 (6.0 – 6.1 mm including wings) (N=5); female 2.8–3.4 (6.3 – 6.4 mm including wings) (N=3).

Coloration. General body color dark yellow ( Figs 4A, B View FIGURE 4 ). Upper half of frons, plaque organs of pedicel, median region of pronotum, lateral and posterior margin of pronotum and tegula pale yellow. Forewing semihyaline, yellow with white and darkened regions: narrow white band covering r-m, r- m2, m-cu 1, icua cross-veins; narrow white stripes covering base of CuA vein, CuP vein and Pcu+A 1 vein; short, wide, transverse brown band extending from to apex the RA vein up to the MP 2 vein at apex of wing; short, wide, transverse brown band extending from MP 4 vein to apex of cubital cell at apex of wing ( Fig. 39C View FIGURE 39 ). Hind wing semihyaline, yellow ( Fig. 39D View FIGURE 39 ). Upper half of sternite III pale yellow ( Fig. 4E View FIGURE 4 ).

Head: frons narrow, distance between the lateral carinae of frons, on median portion, approximately twice smaller than maximum width of vertex ( Fig. 4C View FIGURE 4 ). Clypeus approximately 3 times longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ¾ ( Fig. 4C View FIGURE 4 ). Pedicel oblong, approximately twice longer than scape ( Fig. 37B View FIGURE 37 ). Scape long without cuticular denticles ( Fig. 37B View FIGURE 37 ).

Thorax: anterior margin of pronotum tapered, lateral longitudinal carinae of pronotum converging at an angle on anterior margin and gently diverging towards posterior margin; median longitudinal carina of pronotum present but weakly marked; posterior margin of pronotum shallowly concave, in the middle; pronotum without pustules on posterior margin ( Fig. 4D View FIGURE 4 ); median and lateral longitudinal carinae of mesonotum present but weakly marked ( Fig. 4D View FIGURE 4 ).

Forewing: RA and RP veins with the apex gently curved anteriorly; r-m cross-vein present; ir cross-vein close to of the r-m 1 cross-vein, aligned; MP with four branches with apex gently curved posteriorly; first bifurcation of MP vein arising before r-m cross-vein; m-cu cross-vein present; CuP vein approximately 3 times longer than Pcu + A 1 vein; apex of clavus with straight angle ( Fig. 39C View FIGURE 39 ).

Hind wing: first bifurcation of MP vein arising before m-cu cross-vein ( Fig. 39D View FIGURE 39 ).

Legs: metatibia with 9 apical spines; metatarsus with 7+6 apical spines.

Abdomen: posterior half of sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternites VII + VIII v-shaped in posterior view. Female ( Fig. 4B View FIGURE 4 ). Similar to male, except for long, wide, brown, transverse band y-shaped at apex of forewing; apex of Anal tube (segment X), slightly concave ( Fig. 6A View FIGURE 6 ).

Male terminalia ( Figs 5A–G View FIGURE 5 ). Pygofer with posterior margin without projections and numerous sparse setae ( Fig. 5B View FIGURE 5 ). Gonostyli with truncated apex in lateral view; outer margin with short projection and with a rounded apex near apex and inner margins with sparse setae ( Fig. 5A, D, E View FIGURE 5 ). Phallic complex ( Fig. 5F, G View FIGURE 5 ): Periandrium rounded in dorsal view, dorsal margin with smoothly indentation at the apex and ventral margin rounded apically ( Fig. 5F, G View FIGURE 5 ). Inner sclerotised plates slender, lacking spiniform projections ( Fig. 5 G View FIGURE 5 ). Anal tube (segment X), short, apex rounded in dorsal view, with sparse setae dorsally ( Fig. 5 C View FIGURE 5 ).

Female terminalia ( Figs 6A–E View FIGURE 6 ): Pygofer bilobed with sparse setae in posterior view ( Fig. 6B View FIGURE 6 ). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with small spiniform projections in lateral view; four lateroapical projection of unequal sizes with smooth dorsal margin in lateral view ( Fig. 6E View FIGURE 6 ). Bursa copulatrix sparsely filamentous apically, acute apex, with some sparse setae near apex in lateral view ( Fig. 6E View FIGURE 6 ). Gonapophysis IX (second valvula) robust, wider at the base, forked on apical half, lobes with pointed apex, strongly curved latero-ventrally in dorsal view ( Fig. 6D View FIGURE 6 ). Gonoplac (third valvula) subtrapezoidal, apex rounded with numerous marginal setae (setae lost, only insertions visible), and few sparse setae laterally near apex in lateral view ( Fig. 6C View FIGURE 6 ). Anal tube (segment X), short, apex smoothly reentrant, with sparse setae in dorsal view ( Fig. 6A View FIGURE 6 ).

Variations. Variations in the size and shape of the dark transverse bands on apical half of forewing have been observed in some specimens, as well as the absence of these bands and the median longitudinal carina of pronotum.

Comments. B. banksi ( Metcalf, 1938) can be promptly distinguished from B. guianesus ( Fennah, 1947) by the body color dark yellow, posterior margin of pronotum almost straight, forewing yellow with white and dark regions, dorsal margin of periandrium with smoothly indentation at the apex and ventral margin rounded.
