 Diagnosis. Dorsal stripe above upper half of frons extending to the apex of the mesonotum pale yellow (Fig. 13D). Median carina of clypeus almost touching the epistomal suture (Fig. 13C). MP vein of the forewing with seven branches (Fig. 40A). Dorsal margin of periandrium straight and ventral margin with short indentation (Fig. 14G).   
 Redescription (male and female). Measurements. Body length: male 3.6 – 5.0 mm (6,1 – 8 mm including wings) (N=4); female: 3.3 – 4.4 mm (6.9 – 7.2 mm including wings) (N=3).   
 Coloration. General body color light brown (Figs 13 A, B). Dorsal stripe above upper half of frons extending to the apex of the mesonotum, semitriangular spot in the latero-anterior region of the mesonotum, posterior region of the gena pale yellow (Figs 13 A, D). Epimeron and episternum yellow brown. Forewing dark brown, semihyaline, with white regions and basal half of the veins brown and apical half das veins reddish; narrow white stripes covering c-sc, icua cross-veins; basal region of MP vein white; narrow white stripe extending from the r-m 1 cross-vein to m-cu cross-vein; narrow white stripe extending from the r-m2 cross-vein to the MP 7 vein base; x-shaped region white covering the m-cu 2 cross-vein, median region of the CuA 1 vein and the icua cross-vein; narrow white stripe and short near apex of CuA 2; apex of clavus white; postclaval margin white (Fig. 40A). Hind wing semihyaline, light brown with hyaline regions (Fig. 40B). Legs light brown, except metacoxae and metafemur yellow brown (Fig. 13A). Abdomen light brown, except for a reddish diffuse spot on the sternites III, IV + V and VI (Fig. 13A).   
 Head: frons wide, distance between the lateral carinae of frons, on median portion, approximately half the maximum width of vertex (Fig. 13C). Clypeus approximately twice longer than its maximum width; median carina of clypeus strongly marked, almost touching the epistomal suture (Fig. 13C). Pedicel globose, approximately 3 times longer than scape (Fig. 37E). Scape long with cuticular denticles (Fig. 37E).   
 Thorax: anterior margin of pronotum slightly tapered, lateral longitudinal carinae of pronotum converging at an angle on anterior margin and subparallel to each other 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; median and lateral longitudinal carinae of mesonotum present but weakly marked (Fig. 13D).   
 Forewing: RA and RP veins with the apex strongly curved anteriorly; r-m cross-vein present; ir cross-vein distant from r-m2 cross-vein, not aligned; MP vein with seven 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 3 times longer than Pcu + A1 vein; apex of clavus with straight angle (Fig. 40 A).   
 Hind wing: first bifurcation of MP vein arising before m-cu cross-vein (Fig. 40B).   
 Legs: metatibia with 7 apical spines; metatarsus with 6+5 apical spines.   
 Abdomen: posterior half of sternites IV + V and VI with four long, thin, whitish setae; posterior margin of sternites VII semi-rounded. Female (Fig. 13B). Similar to male, except coloration of gena, epimer and episternum yellowish and reddish stripe on posterior margin of the sternites III, IV + V and VI.   
 Male terminalia (Figs 14A–G): pygofer with posterior margin without projections, with sparse setae in posterior view (Fig. 14A, B). Gonostyli with truncated apex in lateral view, outer margin with short projection and with a pointed apex near apex and inner margin with some setae (Figs 14D, E). Phallic complex (Figs 14F, G): periandrium semitrapezoidal in dorsal view; dorsal margin of periandrium straight at the apex and ventral margin with short indentation apically (Figs 14F, G). Inner sclerotised plates narrowing towards the apex, with serrated margin and surface with small spiniform projections (Figs 14 F, G). Aal tube (segment X), short, apex smoothly reentrant in dorsal view, with sparse setae dorsally (Fig. 14C).   
 Female terminalia (Figs 15A–E): Pygofer with numerous setae in posterior view (Fig. 15B). Gonapophysis VIII (first valvula) robust, with sparse setae in the basal region and median region with small spiniform projections on apical half in lateral view; three lateroapical projection of unequal sizes with irregular teeth on dorsal margin in lateral view (Fig. 15E). Bursa copulatrix densely filamentous apically, straight apex, covered by setae laterally on apical half (Fig. 15E). Gonapophysis IX (second valvula) robust, forked on apical half, lobes with a pointed apex, strongly curved latero-ventrally in dorsal view (Fig. 15D). Gonoplac (third valvula) subtrapezoidal, apex rounded with several apical setae and sparse setae laterally (Fig. 15C). Anal tube (segment X), short, apex rounded, with sparse setae in dorsal view (Fig. 15A).   
 Variations. Variations in the coloration of the veins of the forewing, on basal half, have been observed in some specimens, from light brown to dark brown, and the median longitudinal carina of the mesonotum was absent in some specimens.   
 Distribution. Brazil (Amapá, Amazonas, Pará, Rondônia), Ecuador (Felton) and Peru (Madre de Dios) (Fig. 43).   
 Comments. B. dorsivittata Fennah, 1947 differs from the other species of Bebaiotes by MP vein of the forewing with seven branches, dorsal margin of periandrium without indentation at the apex and ventral margin of periandrium with short indentation apically.
