Diagnosis. Lower half of frons with narrow horizontal light brown band ( Fig. 31C View FIGURE 31 ). Median region of pronotum white ( Fig. 31D View FIGURE 31 ). Posterior margin of pronotum with shallow arched indentation ( Fig. 31D View FIGURE 31 ). Dorsal and ventral margin of periandrium with short indentation ( Fig. 32G View FIGURE 32 ).

Description. Measurements. Body length 2.9 – 3.3 mm (4.8 – 5.4 mm including wings) (N=3); female: 2.5 – 3.2 (5.1 – 5.2 mm including wings) (N=3).

Coloration. General body color whitish brown ( Figs 31A, B View FIGURE 31 ). Pedicel and lateral carinae of the frons dark brown. Forewing semihyaline, dark brown with whitish region: basal half of postcostal cell white; long, wide, whitish diffuse transverse band on median region extending from CA vein up to the icu cross-vein; long, whitish diffuse band covering the RP, MP and CuA veins in wing apex; apex of the whiteclavus ( Fig. 41E View FIGURE 41 ). Hind wing semihyaline, light brown with hyaline regions ( Fig. 41F View FIGURE 41 ). Legs yellow brown, except apex of metatibiae dark brown. Abdomen white, except tergites and sternites IV + V, anterior half of the sternites VI and VII light brown ( Fig. 31A View FIGURE 31 ).

Head: frons wide, distance between the lateral carinae of frons on median portion, subequal to maximum width of vertex ( Fig. 31C View FIGURE 31 ). Clypeus approximately 3 times longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ⅔ ( Fig. 31C View FIGURE 31 ). Pedicel globose, approximately 3 times longer than scape ( Fig. 38E View FIGURE 38 ). Scape short with cuticular denticles ( Fig. 38E View FIGURE 38 ).

Thorax: anterior margin of pronotum with truncated apex, lateral longitudinal carinae of pronotum converging at an angle on anterior margin and gently diverging towards the tegula; median longitudinal carina of pronotum present, strongly marked; posterior margin of pronotum with shallow arched indentation in the middle; pronotum without pustules on posterior margin ( Fig. 31D View FIGURE 31 ); median and lateral longitudinal carinae of mesonotum present, strongly marked ( Fig. 31D View FIGURE 31 ).

Forewing: RA vein with the apex strongly curved anteriorly; RP vein with the apex gently curved anteriorly; rm cross-vein present; ir cross-vein close to r-m2 cross-vein, not aligned; MP vein with four branches with uncurved apex; first bifurcation of MP vein arising after r-m cross-vein; m-cu cross-vein present; CuP vein approximately 5 times longer than Pcu + A 1 vein; apex of clavus with acute angle ( Fig. 41E View FIGURE 41 ).

Hind wing: first bifurcation of MP vein arising after m-cu cross-vein ( Fig. 41F View FIGURE 41 ).

Legs: metatibia with 8 apical spines; metatarsus with 6+6 apical spines. Female ( Fig. 31 B View FIGURE 31 ).

Abdomen: posterior pit of the sternite III rounded ( Fig. 28E View FIGURE 28 ); posterior half of sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternites VII rounded. Female ( Fig. 31B View FIGURE 31 ). Similar to male, except for the coloration of legs ranging from light brown to yellowish brown.

Male terminalia ( Figs 32A–G View FIGURE 32 ). Pygofer with posterior margin without projections, with sparse setae in posterior view ( Fig. 32B View FIGURE 32 ). Gonostyli with truncated apex in lateral view, outer margin with short and pointed projection near the apex, surface and inner margin with some setae ( Figs 32A, D, E View FIGURE 32 ). Phallic complex ( Figs 32F, G View FIGURE 32 ): periandrium narrowing to apex in dorsal view, dorsal and ventral margin with short indentation at the apex ( Fig. 32F, G View FIGURE 32 ). Inner sclerotised plates narrowing towards the apex, with serrated margin and surface with small spiniform projections ( Figs 32F, G View FIGURE 32 ). Anal tube (segment X), short, apex smoothly reentrant in dorsal view, with few sparse setae dorsally ( Fig. 32A View FIGURE 32 ).

Female terminalia ( Figs 33A–E View FIGURE 33 ). Pygofer with several setae in posterior view ( Fig. 33B View FIGURE 33 ). Gonapophysis VIII (first valvula) robust, with few setae on median region and covered with numerous small spiniform projections in the basal half in lateral view; three lateroapical projections of subequal sizes with serrated dorsal margin in lateral view ( Fig. 33E View FIGURE 33 ). Bursa copulatrix sparsely filamentous apically, obtuse apex, few sparse setae on median region,

covered by setae laterally on apical half, and few small spiniform projections near apex in lateral view ( Fig. 33E View FIGURE 33 ). Gonapophysis IX (second valvula) robust, forked on apical half, lobes with pointed apex, strongly curved latero-ventrally, hook-like in dorsal view ( Fig. 33D View FIGURE 33 ). Gonoplac (third valvula) subtrapezoidal, apex rounded with numerous setae apically and few setae laterally in lateral view ( Fig. 33C View FIGURE 33 ). Anal tube (segment X), short, apex truncated, with sparse setae in dorsal view ( Fig. 33A View FIGURE 33 ).

Variations. No variations were observed in the studied specimens.

Etymology. From the Latin tigrinus, tiger. The species name is allusive to the coloration of a tiger.

Distribution. Brazil (Amazonas) ( Fig. 44 View FIGURE 44 ).

Comments. B. tigrina sp. nov. differs from B. dichromata sp. nov. as previously discussed in the description of the latter.
