description: Bebaiotes bia sp. nov.   
 (Figs 7A – E; 8A – G; 9A – E; 37C; 39E, F; 42)   
 Type material. Holotype male (INPA). BRASIL, Acre, Bujari, FES Antimary, 9°20’01”S – 68°19’17”W, 3.viii– 8.ix.2016, Malaise peq[uena], E.F. Morato & J.A. Rafael cols.— Rede BIA.   
 Condition of the holotype. Left flagellum broken and lost. Right forewing torn near the apex. Hind wings torn near the apex.   
 Paratypes. BRASIL, Acre, Bujari, FES Antimary, 9˚20’01”S–68˚19’17”W, 22.ix–06.x.2016, Malaise peq[uena], E.F. Morato & J.A. Rafael cols.— Rede BIA (1 ♂, INPA); idem, 18–31.iv.2017, Malaise grande (2 ♂, 1 ♀, INPA ) ; idem, 19.xi–3.xii.2016 (1 ♂, INPA).   
 Diagnosis. Median longitudinal carina of pronotum weakly marked (Fig. 7D). Scape long (Fig. 37C). Forewing dark brown with whitish regions. Dorsal margin of periandrium with serrated apex (Fig. 8 G). Gonapophysis VIII (first valvula) with four projections on the lateroapical margin with toothed dorsal margin (Fig. 9E).   
 Description. Measurements: Body length: male length 3.7 – 4.0 mm (7.4 – 8.0 mm including wings) (N=3); female 3.4 mm (7.3 mm including wings) (N=1).   
 Coloration. General body color light brown (Fig. 7A, B). Lateral carinae of the frons and upper region of the gena dark brown. Plaque organs of pedicel whitish. epimeron and episternum yellow. Forewing semihyaline, dark brown with whitish regions: yellowish veins; basal half of postcostal cell whitish; narrow whitish band covering CuP vein, Pcu vein, basal half of MP, RP and CuP veins and r-m cross-vein; cells C3a, C3a’, C3’, C3b, C4, C5 light brown (Fig. 39E). Hind wing semihyaline, light brown with hyaline regions (Fig. 39F).   
 Head: frons narrow, distance between the lateral carinae of frons, on median portion, approximately twice smaller than maximum width of vertex (Fig. 7C). Clypeus approximately 3 times longer than its maximum width; median carina of clypeus strongly marked, does not touch epistomal suture, present on distal ¾. Pedicel oblong, approximately twice longer than scape (Fig. 7C). Scape long without cuticular denticles (Fig. 37C).   
 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. 7D). Median longitudinal carina of mesonotum present, but weakly marked, and lateral longitudinal carinae absent (Fig. 7D).   
 Forewing: RA and RP veins with the apex strongly curved anteriorly; r-m cross-vein present; ir cross-vein close to of the r-m 1 cross-vein, aligned; MP vein 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. 39E).   
 Hind wing: first bifurcation of MP vein arising before m-cu cross-vein (Fig. 39F).   
 Legs: metatibia with 8 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 sternite VII semi-rounded. Female (Fig. 7B). Similar to male.   
 Male terminalia (Figs 8A–G): pygofer with median region with small spiniform projection on each side, near the posterior margin, in lateral view (Fig. 8B). Gonostyli with truncated apex in lateral view, outer margin with short projection and with a pointed apex near apex and inner margins with some setae (Figs 8A, D, E). Phallic complex (Figs 8F, G): Periandrium semi-oval, dorsal and ventral margins rounded apically and dorsal margin serrated in dorsal view (Figs 8F, G). Inner sclerotised plates narrowing towards the apex, with serrated margin and surface with small spiniform projections (Figs 8 F, G). Anal tube (segment X), short, apex rounded in dorsal view, with sparse setae dorsally (Fig. 8C).   
 Female terminalia (Figs 9A–E): Pygofer bilobed with numerous setae in posterior view (Fig. 9B). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with small spiniform projections at basal half in lateral view; four lateroapical projection of unequal sizes with toothed dorsal margin in lateral view (Fig. 9E). Bursa copulatrix densely filamentous apically, acute apex, covered by setae laterally near apex (Fig. 9E). Gonapophysis IX (second valvula) slender, wider at the base, forked at apical ¼, lobes with pointed apex, strongly curved latero-ventrally in dorsal view (Fig. 9D). Gonoplac (third valvula) subtriangular, with narrowed and rounded apex, some apical setae and sparse setae laterally on apical half (Fig. 9C). Anal tube (segment X), short, also truncated apex and sparse setae, in dorsal view (Fig. 9A).   
 Variations. Variations in the coloration of the body have been observed in some specimens, from light brown to dark brown, and the median carina of pronotum can be strongly marked. The median longitudinal carina of pronotum was absent in some specimens, and the median longitudinal carina of the mesonotum was observed in one specimen.   
 Distribution. Brazil (Acre) (Fig. 42).   
 Etymology. The species is named in honor of the Rede BIA project (Biodiversity of Insects in the Amazon), which brought together students, technicians and researchers committed to preserving and knowing insects in the Amazon.   
 Comments. Bebaiotes bia sp. nov. can be promptly distinguished from B. wilsoni sp. nov. by the lateral carinae of the frons, dark brown, median longitudinal carinae of the mesonotum absent, anterior margin of pronotum with tapered apex, lateral longitudinal carinae of pronotum converging at an angle, median longitudinal carinae of mesonotum absent, CuA vein bifurcation arising before r-m cross-vein; ventral margin of periandrium rounded at the apex and gonapophysis VIII (first valvula) with four projections on lateroapical margin.
