Description
: Coloration. General body color light brown (
Figs 66–67
). 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.

. Gonapophysis VIII, lateral view (first valvula);

. 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
) (

).
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.
