Penny (1 ♀ INPA); N. de Manaus, Km 60, 9–10.iv.1980,2202, N. D. Penny (1 ♂ INPA) .

Diagnosis. Lower half of frons dark brown ( Fig. 10C View FIGURE 10 ). Median carina of clypeus weakly marked ( Fig. 10C View FIGURE 10 ). Protibiae and protarsus dark brown ( Fig. 10 A View FIGURE 10 ). Forewing dark brown with white regions ( Figs 10A, B View FIGURE 10 ). Dorsal margin of periandrium with long indentation ( Fig. 11G View FIGURE 11 ).

Description. Measurements. Body length: male 2.4 – 2.5 mm (4.9 – 5.3 mm including wings) (N=3); female 3.0 mm (5.0 mm including wings) (N=1).

Coloration. General body color yellow ( Figs 10 A–D View FIGURE 10 ). Pedicel, lower half of frons dark brown. Pronotum predominantly yellow, except lateral region to the lateral longitudinal carina light brown. Mesonotum predominantly light brown, except lateral longitudinal carinae, median longitudinal carina, irregular spot on anterolateral region yellow. Forewing semihyaline, dark brown with white regions: long, wide, whitish diffuse transverse band in the basal region extending from to CA vein up to the CuA vein; long, wide, whitish diffuse transverse band in the middle region extending from to CA vein up to the CuA 1 vein; half basal of the cubital cell white; long, whitish diffuse band on apical region, extending from the apex of the postcostal cell to the icua cross-vein; white icu cross-vein; long whitish diffuse band covering radial, MP and CuA veins at apex of the wing ( Fig. 39G View FIGURE 39 ). Hind wing semihyaline, light brown with hyaline regions ( Fig. 39H View FIGURE 39 ). Legs yellow, except all tibiae and tarsus dark brown. Abdomen yellow, except sternite IV light brown ( Fig. 10E View FIGURE 10 ).

Head: frons wide, distance between the lateral carinae of frons on median portion, subequal to maximum width of vertex ( Fig. 10C View FIGURE 10 ). Clypeus approximately twice longer than its maximum width; median carina of clypeus weakly marked, does not touch epistomal suture, present on distal 1 / 2 ( Fig. 10C View FIGURE 10 ). Pedicel globose, approximately 4 times longer than the scapus ( Fig. 37 D View FIGURE 37 ). Scape short without cuticular denticles ( Fig. 37D View FIGURE 37 ).

Thorax: anterior margin of pronotum slightly tapered, also rounded, 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, strongly marked; posterior margin of pronotum with slight angled indentation in the middle; pronotum without pustules on posterior margin ( Fig. 10D View FIGURE 10 ); median and lateral longitudinal carinae of mesonotum present but weakly marked ( Fig. 10D View FIGURE 10 ).

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, not aligned; MP vein with four branches with straight apex; first bifurcation of MP vein arising after r-m cross-vein; m-cu cross-vein present; CuP vein approximately 7 times longer than Pcu + A 1 vein; apex of clavus with acute angle ( Fig. 39G View FIGURE 39 ).

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

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; sternites VII + VIII completely sclerotised; posterior margin of sternite VII semi-rounded. Female ( Fig. 10B View FIGURE 10 ). Similar to male, except the shape of the anal tube.

Male terminalia ( Figs 11A–G View FIGURE 11 ): pygofer with posterior margin without projections ( Fig. 11 B View FIGURE 11 ). Gonostyli with rounded apex in lateral view and outer margin with short projection and with a pointed apex near apex and sparse setae on inner margin ( Figs 11A, D, E View FIGURE 11 ). Phallic complex ( Figs 11F, G View FIGURE 11 ): Periandrium apically narrowed in dorsal view; dorsal margin with long indentation at the apex and ventral margin with short indentation at the apex in dorsal view ( Figs 2F, G View FIGURE 2 ). Inner sclerotised plates narrowing towards the apex, with serrated outer margin at the apex and smooth surface, without projections ( Figs 11F, G View FIGURE 11 ). Anal tube (segment X), short, apex truncated in dorsal view, with sparse setae dorsally ( Fig. 11C View FIGURE 11 ).

Female terminalia ( Figs 12A–E View FIGURE 12 ): Pygofer with numerous setae in posterior view ( Fig. 12B View FIGURE 12 ). Gonapophysis VIII (first valvula) robust, with sparse setae on median region and covered with small spiniform projections in the basal half in lateral view; three lateroapical projections of subequal sizes with serrated dorsal margin in lateral view ( Fig. 12E View FIGURE 12 ). Bursa copulatrix densely filamentous apically, obtuse apex, covered by setae laterally on apical half in lateral view ( Fig. 12E View FIGURE 12 ). Gonapophysis IX (second valvula) robust, forked on apical half, lobes with a pointed apex, strongly curved latero-ventrally, hook-like in dorsal view ( Fig. 12D View FIGURE 12 ). Gonoplac (third valvula) subtrapezoidal, apex rounded with several apical setae and sparse setae laterally ( Fig. 12C View FIGURE 12 ). Anal tube (segment X), short, apex truncated, with many sparse setae in dorsal view ( Fig. 12B View FIGURE 12 ).

Variations. Variations have been observed in the coloration of the body in some specimens, from yellowish to yellowish-brown.

Etymology. From the Greek di, two, chroma, color. The species name is allusive to the color of antennae (pedicel + scape).

Distribution. Brazil (Amazonas) ( Fig. 42 View FIGURE 42 ).

Comments. Bebaiotes dichromata sp. nov. can be promptly distinguished from B. tigrina sp. nov. by clypeus without brown band, posterior margin of pronotum with slight angled indentation in the middle, in dorsal view, dorsal margin of periandrium with long indentation at the apex and bursa copulatrix densely filamentous apically.
