 Diagnosis. Body coloration yellowish brown (Figs 1A, B). Median longitudinal carina of pronotum strongly marked (Fig. 1D). Longitudinal carinae of mesonotum strongly marked (Fig. 1D). Dorsal margin of periandrium with short indentation (Fig. 2G).   
 Description. Measurements: Body length: male 2.3 – 3.7 mm (5.1 – 5.4 mm including wings) (N=20); female: 2.3 – 3.6 mm (5.0 – 5.5 mm including wings) (N=15).   
 Coloration. General body color yellow brown (Figs 1A, B). Plaque organs of pedicel, epimeron and episternum pale yellow. Forewing semihyaline, light brown with whitish regions: narrow white band covering r-m, r-m2, m1– m2, m-cu, icua cross-veins; apex of the whitish clavus (Fig. 39A). Hind wing semihyaline, light brown with hyaline regions (Fig. 39B). Legs yellow brown, except apex of metatibiae and metatarsus, dark brown.   
 Head: frons wide, distance between the lateral carinae of frons, on median portion, subequal to maximum width of vertex (Figs 1C, D). Clypeus approximately twice longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ¾ (Fig. 1C). Pedicel globose, approximately 4 times longer than scape (Fig. 37A). Scape short with cuticular denticles (Fig. 37A).   
 Thorax: anterior margin of pronotum with truncated apex, lateral longitudinal carinae of pronotum converging horizontally anteriorly and gently diverging towards posterior margin; median longitudinal carina of pronotum present, strongly marked; posterior margin of pronotum with slight angled indentation in the middle; pronotum without pustules on posterior margin (Fig. 1D); median and lateral longitudinal carinae of mesonotum present, strongly marked (Fig. 1D).   
 Forewing: RA and RP veins with the apex gently curved anteriorly; r-m cross-vein absent; ir cross-vein close to the r-m2 cross-vein, not aligned; MP vein with four branches with uncurved apex; first bifurcation of MP vein arising before r-m cross-vein; m-cu cross-vein present; CuP vein approximately 8 times longer than Pcu + A 1 vein; apex of clavus with acute angle (Fig. 39A).   
 Hind wing: first bifurcation of MP vein arising after m-cu cross-vein (Fig. 39B).   
 Legs: metatibia with 9 apical spines; metatarsus with 6+6 apical spines.   
 Abdomen: posterior half of sternites IV + V and VI with three long, thin, whitish setae; posterior margin of sternites VII semi-rounded. Female (Fig. 1B). Similar to male, except for abdomen dark brown.   
 Male terminalia (Figs 2A–G): Pygofer with posterior margin with short triangular protuberance on each side near the median region, with sparse setae in posterior view (Fig. 2A). Gonostyli with rounded apex in lateral view, outer margin with short projection and with a pointed apex near apex and inner margins with some micro setae (Figs 2B, D, E). Phallic complex (Figs 2F, G): periandrium semi-oval in dorsal view (Fig. 2G), dorsal and ventral margin with short indentation at the apex (Fig. 2G). Inner sclerotised plates narrowing towards the apex, with serrated margin and surface with small spiniform projections (Figs 2F, G). Anal tube (segment X), short, apex rounded, with many sparse setae in dorsal view (Fig. 2C).   
 Female terminalia (Figs 3A–E): Pygofer with numerous setae and small spiniform projections near ventral region in posterior view (Fig. 3B). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with covered with small spiniform projections in the basal half in lateral view; three lateroapical projection of subequal sizes with serrated dorsal margin in lateral view (Fig. 3E). Bursa copulatrix densely filamentous apically, obtuse apex, covered by setae laterally on apical half (Fig. 3E). Gonapophysis IX (second valvula) robust, bifid on apical half, lobes with pointed apex, strongly curved latero-ventrally, hook-like in dorsal view (Fig. 3D). Gonoplac (third valvula) subtrapezoidal in lateral view, apex rounded with dense apical setae and sparse setae laterally (Fig. 3C). Anal tube (segment X), subtrapezoidal in dorsal view, robust (Fig. 3A).   
 Variations. Variations in the coloration of the forewing veins have been observed in some specimens, from yellow to brown, and on sternite III the coloration varies from yellowish brown to dark brown. Variations in the size of the median longitudinal carina of pronotum also have been observed: from complete, reaching the entire extension of the median region of pronotum, and incomplete, not reaching the entire extension of the median region of pronotum.   
 Etymology. The species is named in reference to the Amazon Region, where it was collected.   
 Comments. B. amazonica sp. nov. can be promptly distinguished from B. parallela sp. nov. by the body coloration, yellow brown, median longitudinal carina of pronotum strongly marked, CA vein uniformly yellowish brown and dorsal margin of the phallic complex with short indentation at the apex.   
 Distribution. Brazil (Amazonas, Pará, Rondônia and Roraima) (Fig. 42).
