Lateral carinae of the frons above lateral ocelli, apical half of the clypeus, vertex, median region of pronotum and mesonotum yellow. Forewing: basal half light brown and apical half with several small whitish and brown areas: long, white diffuse band in the middle portion of postcostal cell extending to until the icua cross-vein; white, diffuse spot at apex of postcostal extending to the sc-r cross-vein; C1 and C1’ cells predominantly white; apical half of the C2 cell white; white rounded spot at apex of cells C2 ‘, C3a, C3a”, C3’ and C3b; big white longitudinal spot inside cell C3; C4’ cell predominantly white; small white spot on the apex of the clavus ( Fig. 130 ). Pterostigma yellow. Hindwing hyaline, brown. Foreleg and mid leg dark brown, hind leg yellowish brown ( Fig. 66 ). Abdomen dark brown, except upper half of sternite III, dorsal region of sternite IV and V yellow; anal tube, pygofer and genital style yellowish brown ( Figs 66, 70 ). Head: frons with median carina present but weakly marked; lateral carina of frons weakly directed obliquely laterally ( Fig. 68 ); vertex length approximately half the median length of the pronotum in dorsal view ( Fig. 69 ); pedicel approximately 4 times longer than wide and scape conspicuous in anterior view ( Fig. 68 ). Thorax: pronotum with median longitudinal carina absent; mesonotum with median and lateral longitudinal carinae present and strongly marked ( Fig. 69 ). Forewing: m-cu cross-vein present ( Fig. 130 ). Legs: hind tibia with 6 apical spines; hind tarsus with 8+7 apical spines. FIGURES 78–83. Bennarella maculipennis sp. nov. , female genitalia: 78 .

Apex of the gonapophysis IX (second valvula); 83 . Apex of the gonapophysis VIII, lateral view (first valvula). Scale bars: 78 = 0.2 mm; 79–83 = 0.1 mm. Male terminalia ( Figs 71–77 ). Pygofer subtriangular in lateral view, posterior margin with short triangular protuberance on each side in the middle region ( Fig. 71 ); medioventral process of pygofer conspicuous in lateral view, with posterior margin triangular in ventral view ( Figs 71, 73 ). Gonostyli with rather truncated apex in lateral and dorsal view ( Figs 74, 75 ); basal half narrow and slightly widened in the middle, distal half wider and divergent apically in dorsal and posterior views ( Figs 73, 75 ). Phallic complex ( Figs 76–77 ): periandrium almost straight bearing one slender, elongated, and straight spine anteriorly directed (S1), and one slender, elongated, slightly curved spine anteroventrally directed (S2); aedeagus narrow, widening distally with two spines: one short, slender, in the median region (S3), and one short, slender, near the apex (S4). Anal tube with dorsal margin almost straight; base of the anal tube long, approximately 2 times length of anal tube extension in lateral view; anal tube extension abruptly folded ventrally at apex in lateral view, apex smoothly reentrant in posterior view ( Figs 71–73 ). Female terminalia ( Figs 78–83 ). Pygofer elongate, symmetrical, about 3 times longer than the greatest width in ventral view ( Fig. 78 ). Gonoplac (third valvula) longer than wide, apex rounded in lateral view ( Fig. 79 ). Gonapophysis IX (second valvula) strongly sclerotized dorsally, tapered towards apex ( Fig. 80 ); with approximately 13 denticles (de) at distal 1/3 ( Fig. 82 ). Gonapophysis VIII (first valvula) longer than wide, slender, slightly curved upwards ( Figs 81, 83 ). Anal tube slightly narrowed towards the apex in lateral view. Etymology. From the Latin macula , spot and penna , wing. The species name is allusive to the presence of whitish spots on the apex of the forewing. Distribution . Brazil ( Amazonas and Bahia ) ( Fig. 135 ). Taxonomic notes. Bennarella maculipennis sp. nov. is a distinctive species and differs from the other species of Bennarella by forewing with m-cu cross-vein present, forewing with small white spots on apical half, male terminalia with anal tube straight with long base and apex smoothly reentrant, two spines on periandrium and on aedeagus.
