Measurements: Body length: male 2.1–2.9 mm (4.6–5.1 mm including wings) (N=4); Forewing length: male 4.0– 4.4 mm (N=4).

Diagnosis. Frons with median carina present, but weakly marked. Forewing with basal half yellow and apical half brown; m-cu cross-vein absent. Male anal tube elongated, base of the anal tube very short, approximately 1/3 length of the anal tube extension, apex rounded. Pygofer with posterior margin concave. Periandrium with one long, falciform projection with bifid apex.

Description. Coloration. General body color light brown ( Fig. 59 View FIGURES 59–65 ). Frons dark brown, except lateral carinae of the frons above lateral ocelli yellowish. Vertex, tegula, median region of pronotum and mesonotum, epimeron and episternum yellow. Forewing: basal half yellow and apical half brown, with white regions: long, white diffuse band in the middle portion of postcostal cell extending to until the fusion of the medial vein with cubital vein; white rectangular strip at the apex of the postcostal cell extending to the sc-r cross-vein; basal half of the postcostal cell brown; white y-shaped spot inside cell C2; small white longitudinal spot inside cell C3; C4 cell predominantly white; white irregular spot involving cell C4, apex of cell C5, cell C5’ and apex of cell cubital ( Fig. 129 View FIGURES 126–133 ). Pterostigma brown. Hindwing hyaline, yellowish. Foreleg dark brown, except fore tibiae yellow on proximal third; mid leg light brown; hind leg yellow, except apex of femur and base of tibia dark brown ( Fig. 55 View FIGURES 55–58 ). Abdomen dark brown, except upper half of sternite III, dorsal region of sternite IV and V pale yellow and anal tube, pygofer and genital style yellow ( Figs 55, 58 View FIGURES 55–58 ).

Head: frons with median carina present, but weakly marked; lateral carina of frons weakly directed obliquely laterally ( Fig. 56 View FIGURES 55–58 ); vertex length subequal to the median length of the pronotum in dorsal view ( Fig. 57 View FIGURES 55–58 ); pedicel approximately 5 times longer than wide and scape conspicuous in anterior view ( Fig. 56 View FIGURES 55–58 ). Thorax: pronotum with median longitudinal carina present but weakly marked; mesonotum with lateral longitudinal carina present and strongly marked ( Fig. 57 View FIGURES 55–58 ). Forewing: m-cu cross-vein absent ( Fig. 129 View FIGURES 126–133 ). Legs: hind tibia with 6 apical spines; hind tarsus with 7+7 apical spines.

Male genitalia ( Figs 59–65 View FIGURES 59–65 ). Pygofer narrower in the dorsal half, widening to the ventral half in lateral view, posterior margin concave and without projections ( Fig. 59 View FIGURES 59–65 ); medioventral process of pygofer conspicuous in lateral view, with posterior margin rounded in ventral view ( Fig. 59 View FIGURES 59–65 ). Gonostyli approximately the same diameter in lateral view ( Fig. 62 View FIGURES 59–65 ), apex bifid and divergent apically in dorsal and posterior views ( Figs 61, 63 View FIGURES 59–65 ). Phallic complex ( Figs 64–65 View FIGURES 59–65 ): periandrium and aedeagus not distinguished, bearing two subbasal projections with bifid apex, a dorsal, long and robust falciform projection and a ventral, long and slender, almost straight projection; one shorter and slender spine (S1), one elongate comma-like spine (S2) near base. Anal tube concave ventrally, asymmetrical; base of the anal tube very short, approximately 1/3 length of the anal tube extension in lateral view, apex rounded in posterior view ( Figs 59–61 View FIGURES 59–65 ).

Etymology. This species is named after Dr. Augusto Loureiro Henriques from the National Institute of Amazonian Research - INPA, Manaus, Brazil, collector of part of the material of this species, for his relevant contribution to the knowledge to the Brazilian invertebrate fauna.

Distribution. Brazil (Amazonas and Maranhão) ( Fig.135 View FIGURE 135 ).

Taxonomic notes. Bennarella henriquesi sp. nov. is a very distinctive species and can be easily distinguished from the other species of Bennarella by forewing with base yellow, lighter than apex, male terminalia with anal tube with rounded apex, pygofer short, abruptly shortened on the dorsal half, approximately 3 times narrower than in the other Bennarella species, and periandrium with one long falciform projection with bifid apex.
