description: Bennarella guidai sp. nov.
(Figs 37–41, 128, 134)
Type material. Holotype male (INPA). BRASIL, Amazonas, Barcelos, Serrinha, 0˚25’05”N–63˚23’05”W, vii– viii.2007, Malaise em floresta, A.S. Filho & T. Krolow cols.
Condition of the holotype: right and left antennal flagellum lost. Hind tibia and hind tarsus lost. Right forewing torn near the apex.
Paratypes. BRASIL, Amazonas, Barcelos, Serrinha, 0˚25’05”N–63˚23’05”W, vii–viii.2007, Malaise em floresta, A.S. Filho & T. Krolow cols. (6 ♂, 7 ♀ INPA).
Measurements: Body length: male 2.0– 2.1 mm (3.7–4.0 mm including wings) (N=5); female 2.0– 2.1 mm (3.8–4.0 mm including wings) (N=5). Forewing length: male 3.3–3.5 mm (N=5); female. 3.2–3.6 mm (N=5).
Diagnosis. Frons with median carina present but weakly marked. Pronotum with median longitudinal carina absent. Forewing with m-cu cross-vein absent. Male terminalia with anal tube with apex bifid. Periandrium without spines and aedeagus with three spines.
Description. Coloration. General body color dark brown (Figs 37–38). Lateral carinae of the frons above lateral ocelli, vertex, median region of pronotum and mesonotum, epimeron and episternum yellow. Forewing: basal half dark brown and apical half light brown, with white regions; white rectangular spot in the middle portion of postcostal cell; narrow, white, transverse band at the base of the subcostal cell; narrow white stripes covering of r-m cross-vein extending to until the fusion of the medial vein with cubital vein; narrow white band within the clavus in the basal region; white postclaval margin; apex of the white clavus; long, whitish, longitudinal band inside cell C2; small narrow white longitudinal band inside cell C3; white, longitudinal band at apex of the cubital cell extending up to the cell C5’ (Fig. 128). Pterostigma light brown. Hindwing light brown. Legs dark brown, except hind coxae yellow (Figs 37–38). Upper half of sternite III, dorsal region of sternite IV and V yellow brown (Figs 37– 38, 41).
Head: frons with median carina present but weakly marked; lateral carinae of frons weakly directed obliquely laterally (Fig. 39); vertex length approximately half the median length of the pronotum in dorsal view (Fig. 40); pedicel approximately 5 times longer than wide and scape conspicuous in anterior view (Fig. 39). Thorax: pronotum with median longitudinal carina present but weakly marked; mesonotum with median and lateral longitudinal carinae present and strongly marked (Fig. 40). Forewing: m-cu cross-vein absent (Fig. 128). Legs: hind tibia with 6 apical spines; hind tarsus with 7+ 7 apical spines.
Male terminalia (Figs 42–48). Pygofer subtriangular in lateral view, posterior margin without projections and almost straight (Fig. 42); medioventral process of pygofer conspicuous in lateral view, with posterior margin triangular in ventral view (Fig. 42). Gonostyli with pointed apex in lateral view (Fig. 45); inner margin widening in the apical third, divergent apically in dorsal and posterior views (Figs 44, 46). Phallic complex (Figs 47–48): periandrium without spines; aedeagus slightly concave with three spines: one short, slender, curved spine inserted near base (S1), one elongated, almost straight spine, inserted in the median region (S2), and one short, straight spine near apex (S3). Anal tube robust, concave ventrally; base of anal tube subequal in length to anal tube extension in lateral view, apex deeply reentrant, bifid, with two robust parallel lobes (Figs 42–44).
Female terminalia (Figs 49–54). Pygofer elongate, symmetrical, about 3 times longer than the greatest width in posterior view (Fig. 49). Gonoplac (third valvula) longer than wide, pointed apex in lateral view (Fig. 50). Gonapophysis IX (second valvula) little sclerotized dorsally, tapered towards apex (Fig. 51), with approximately 13 denticles (de) on distal 1/3 (Fig. 53). Gonapophysis VIII (first valvula) slender, slightly curved upwards (Figs 52, 54). Anal tube slightly narrowed towards the apex in lateral view.
Etymology. In posthumous tribute to Elberte Ferreira Guida do Santos, a great friend who even in the face of adversity and challenges presented himself as a warrior for life and the achievement of his dreams.
Distribution. Brazil (Amazonas) (Fig. 134).
Taxonomic notes. Bennarella guidai sp. nov. is similar to Bennarella vittata sp. nov. in the general coloration of body but can differs from the latter by lateral carina of frons strongly directed obliquely laterally, pronotum with carina present, mesonotum with lateral longitudinal carina present, forewing with m-cu cross-vein absent, male terminalia with anal tube with apex bifid, periandrium without spines and aedeagus with three spines.
