Measurements: Body length: male 2.0–3.0 mm (3.5–4.5 mm including wings) (N=10); female 2.0– 2.6 mm (4.0– 4.5 mm including wings) (N=5). Forewing length: 4.0– 4.5 mm (N=10); female. 3.5–4.0 mm (N=5).
Diagnosis. Frons with median carina present and strongly marked. Mesonotum brown, with dark brown lateral margins. Male terminalia with anal tube concave ventrally, cup-shaped. Pygofer with a long spiniform projection of different sizes on each side of the posterior margin. Periandrium with one long spine at apex and aedeagus with four spines.
Redescription (male e female). Coloration. General body color dark brown (Figs 19–20). Lateral carinae of the frons above lateral ocelli, vertex, median region of pronotum, epimeron and episternum yellow. Mesonotum brown, with dark brown lateral margins. Forewing brown, with white regions; long, white, diffuse band in the middle portion of postcostal cell extending to the fusion of the medial vein with cubital vein; white rectangular strip at apex of the postcostal cell extending to the RA1 vein; narrow white stripes covering base of medial vein; predominantly white clavus region; apex of the cubital cell white; white y-shaped spot inside cell C2; white longitudinal spot inside cell C3 (Fig. 127). Pterostigma light brown. Hindwing light brown. Legs dark brown, except fore tarsus, mid tibia, mid tarsus, 2/3 basal of hind femur, most part of hind tibia and hind tarsus yellow (Figs 19–20). Upper half of sternite III, dorsal region of sternite IV and V pale yellow (Figs 19–20, 23).
Head: frons with median carina present and strongly marked; lateral carinae of frons strongly directed obliquely laterally (Fig. 21); vertex length subequal to the median length of the pronotum in dorsal view (Fig. 22); pedicel approximately 7 times longer than wide and scape inconspicuous in anterior view (Fig. 21). Thorax: pronotum with median longitudinal carina present, strongly marked in dorsal view; mesonotum with median and lateral longitudinal carinae present, strongly marked in dorsal view (Fig. 22). Forewing: m-cu cross-vein absent (Fig. 127). Legs: hind tibia with 6 apical spines; hind tarsus with 7+7 apical spines.
Male terminalia (Figs 24–30). Pygofer subtriangular in lateral view, posterior margin with a long spiniform projection of different sizes on each side, above the middle, and convergent in posterior view (Fig. 24); medioventral process of pygofer conspicuous in lateral view, with posterior margin round in ventral view (Fig. 24). Gonostyli with pointed apex in lateral view (Fig. 27); with inner margin almost straight at basal two-thirds, divergent at distal third and apex triangular in dorsal and posterior views (Figs 26, 28). Phallic complex (Figs 29–30): periandrium slender, sinuous, bearing one slender, elongate, almost straight spine inserted at the apex (S1); aedeagus with four spines: one short, slender, straight spine (S2), one short comma-like spine (S3) in the median region, and two long, slender, slightly curved spines inserted at the apex (S4 and S5). Anal tube concave ventrally, like a cup-shaped dorsal plate over aedeagus; base of anal tube subequal in length to anal tube extension in lateral view (Figs 24–26).
Female terminalia (Figs 31–36). 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. 32). Gonapophysis IX (second valvula) weakly sclerotized dorsally, tapered towards apex (Fig. 33), with approximately 15 denticles (de) in distal 1/3 (Fig. 35). Gonapophysis VIII (first valvula) slender, slightly curved upwards (Figs 34, 36). Anal tube slightly narrowed towards the apex in lateral view.
Distribution. Brazil (Acre, Amapá, Amazonas, Bahia, Maranhão, Pará, Roraima) (Fig.135).
Taxonomic notes. Bennarella fusca Muir differs from the other species of Bennarella by the coloration of the median region of mesonotum brown, anal tube cup-shaped, pygofer with one long spiniform projection on each side of the posterior margin.
