description: Bennarella maculipennis sp. nov.
(Figs 66–83, 130, 135)
Type material. Holotype male (INPA): Brasil, Amazonas, Manaus, Res [erva] Ducke, Ig [arapé] Tinga, 08-18.ix.2004, Arm[adilha] suspensa, 20 m, A. Henriques et al. cols.
Condition of the holotype: Right and left antennal flagellum lost. Right foreleg lost; mid legs lost. Right forewing torn near the apex.
Paratypes. Brasil, Amazonas, Manaus, Res [erva] Ducke, Ig [arapé] Tinga, 06–16.xii.2004, arm[adilha] Malaise (1 ♂, INPA); Bahia, Cachoeira, Fazenda Vila Rial, 8–19.i.2010, Malaise suspensa 2, Bosque da Jaqueira, E. Alvim; C. Mota col (1 ♀, INPA).
Measurements: Body length: male 2.2 mm (4.5 mm including wings) (N=1); female 2.5 mm (4.5 mm including wings) (N=1). Forewing length: male 4.0 mm (N=1); female. 3.7 mm (N=1).
Diagnosis. Frons with median carina present but weakly marked. Pronotum with median longitudinal carina absent. Forewing with apical half with several small white and brown areas, pterostigma yellow; forewing with m-cu cross-vein present. Male anal tube with base long, approximately 2 times length of the anal tube extension in lateral view. Periandrium and aedeagus with two spines each.
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.
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.
