Measurements: Body length: male 2.4–3.0 mm (4.4–5.2 mm including wings) (N=10); female 2.6–2.7 mm (4.8–5.0 mm including wings) (N=5). Forewing length: male 4.1–4.5 mm (N=10); female. 4.2–4.4 mm (N=5).

Diagnosis. Frons with median carina present and strongly marked. Forewing with basal half pale brown and apical half hyaline. Male terminalia with anal tube bearing a produced lobe near base, periandrium with two short preapical spines and a long, widening toward apex, ventral projection close to the base, and aedeagus flat with one spine at the base.

Redescription (male and female). Coloration. General body color light brown with yellow regions ( Figs 1–2 ). Lateral carinae of the frons above lateral ocelli and close to the median ocellus, median carina of the frons, vertex, pedicel, apical half of clypeus, maxillary lobe, tegula, carinae of pronotum and mesonotum pale yellow. Forewing: basal half pale brown and apical half hyaline; yellow veins, except basal half of the anterior cubital vein and postcubitus vein brown ( Fig. 126 ). Pterostigma yellow. Hindwing yellow. Legs light brown, except forecoxae, fore trochanter, mid coxae, mid trochanter, anterior half of the mid femur, hind femur, basal 2/3 of hind tibia pale yellow ( Figs 1–2 ). Male with upper half of sternite III, dorsal region of sternite IV and V pale yellow; pygofer, anal tube and gonostyli yellowish brown ( Fig. 1 ).

Head: frons with median carina present and strongly marked; lateral carinae of frons weakly directed obliquely laterally ( Fig. 3 ); vertex length approximately half the median length of the pronotum in dorsal view ( Fig. 4 ); pedicel approximately 3 times longer than wide and scape conspicuous in anterior view ( Fig. 3 ). Thorax: pronotum with median longitudinal carina present, but weakly marked in dorsal view ( Fig. 4 ); mesonotum with median and lateral longitudinal carinae present and strongly marked in dorsal view ( Fig. 4 ). Forewing: m-cu cross-vein absent ( Fig. 126 ). Legs: hind tibia with 6 apical spines; hind tarsus with 6+7 apical spines.

Male terminalia ( Figs 6–12 ). Pygofer subtriangular in lateral view, posterior margin without projections ( Fig. 6 ); medioventral process of pygofer inconspicuous in lateral view, with posterior margin round in ventral view ( Fig. 6 ). Gonostyli with triangular apex in lateral view ( Fig. 9 ); basal half almost straight, distal half widened and divergent, with truncate apex in dorsal and posterior views (Figs 8,10). Phallic complex ( Figs 11–12 ): periandrium straight with a long basiventral projection widening toward apex bearing two short slender ventral preapical spines (S1 and S2), and three apical, almost straight, spines (S3, S4 and S5): two short spines approximately the same size (S3 and S4), and one spine (S5) approximately 2 times longer than spines S3 and S4; aedeagus flat with one long, slightly curved spine inserted near base (S6). Anal tube with a well-produced ventral lobe near base ( Fig. 6 ), subpentagonal in dorsal view ( Fig. 7 ); base of the anal tube subequal in length to the anal tube extension in lateral view, apex triangular in posterior view ( Fig. 8 ).

Female terminalia ( Figs 13–18 ). Pygofer elongate, symmetrical, about 3 times longer than the greatest width in ventral view. Gonoplac (third valvula) longer than wide, apex rounded in lateral view ( Fig. 14 ). Gonapophysis IX (second valvula) strongly sclerotized dorsally, tapered towards apex ( Fig. 15 ); with approximately 13 denticles (DE) in distal 1/3 ( Fig. 17 ). Gonapophysis VIII (first valvula) very narrow, slightly curved upwards ( Figs 16, 18 ). Anal tube slightly narrowed towards the apex in lateral view.

Distribution. Brazil (Acre, Amapá, Amazonas, Roraima) and Guyana (Tumatumari) ( Fig. 134 ).

Taxonomic notes. B. bicoloripennis Muir differs from the other species of Bennarella by the coloration of the body and wing, and characters of the male genitalia.
