Bennarella vittata sp. nov.

(Figs 95–106, 132, 134)

Type material. Holotype male (INPA). Brasil, Amazonas, Manaus, [Reserva] Soka Gakkai, 14–23.iv.2000. Susp [ensa] baixa, campina, J. Vidal col.

Condition of the holotype: left antennal flagellum lost. Only the right hind leg present, the remaining lost. Right forewing mounted between coverslips.

Paratype. BRASIL, Amazonas, Manaus, [Reserva] Soka Gakkai, 14–23.iv.2000. Susp [ensa] baixa, campina, J. Vidal col. (1 ♂ INPA).

Measurements: Body length: male 2.0– 2.2 mm (3.4–4.1 mm including wings) (N=2); Forewing length: male 3.0– 3.4 mm (N=2).

Diagnosis. Frons with median carina present but weakly marked. Lateral carinae of the frons, above lateral ocellus, yellow for a long distance, extended beyond half the height of the eye. Pronotum with median longitudinal carina absent. Periandrium bearing one spine and aedeagus with two spines.

Description: Coloration. General body color dark brown (Figs 95–96). Lateral carinae of the frons above lateral ocelli, vertex, median region of pronotum and mesonotum, epimeron and episternum yellow. Forewing brown, darker on basal half, with white regions: oval spot in the median region of the costal cell, C2 and C5’ cells predominantly white, C3 cell with a horizontal narrow strip, at the apex of the cubital cell, on the postclaval margin, and at the apex of the clavus (Fig. 132). Pterostigma brown. Hindwing semihyaline, light brown. Legs dark brown (coloration observed in the paratype). Upper half of sternite III, dorsal region of sternite IV and V yellow (Figs 95, 99).

Head: frons with median carina present, but weakly marked; lateral carina of frons weakly directed obliquely laterally (Fig. 97); vertex length approximately half the median length of the pronotum in dorsal view (Fig. 98); pedicel approximately 5 times longer than wide and scape conspicuous (Fig. 97). Thorax: pronotum with median longitudinal carina absent; mesonotum with median and lateral longitudinal carinae present, but weakly marked (Fig. 98). Forewing: m-cu cross-vein present (Fig. 132). Legs: hind tibia with 6 apical spines; hind tarsus with 7+7 apical spines.

Male terminalia (Figs 100–106). Pygofer subtriangular in lateral view, posterior margin without projections (Fig. 100); medioventral process of pygofer conspicuous in lateral view, with posterior margin triangular in ventral view (Fig. 100). Gonostyli with pointed apex in lateral view (Fig. 103); narrowed at basal two third, wider in the apical third and divergent apically in dorsal and posterior views (Figs 102, 104) Phallic complex (Figs 105–106): periandrium almost straight with one long, slender and sinuous spine, inserted at median region (S1); aedeagus slender with bifid apex divided into a curved and an almost straight tip, and two spines: one short spine inserted near base (S2), and one long straight spine, inserted in the median region (S3). Anal tube concave in ventral view; base of the anal tube approximately 0.6 times the length of anal tube extension in lateral view; anal tube extension expanded ventrally, with apex smoothly reentrant in posterior view (Figs 88–90).

Etymology. From the Latin vittae, stripe. The species name is allusive to a yellow stripe that extends from the vertex to the apex of the clavus.

Distribution. Brazil (Amazonas) (Fig.134).

Taxonomic notes. Bennarella vittata sp. nov. differs from Bennarella guidai sp. nov. as previously discussed.
