Australopericoma onofrei Araújo & Bravo sp. nov.

( Figs. 1–11 View FIGURE 1–11 )

Type material. Holotype male: Brazil, Bahia, Serra da Jibóia, Sede Gambá , 10.V.2017, [light trap], Silva-Neto, Mendes & Moura legs . Paratypes: 2 males with the same data as holotype .

Etymology. The species is dedicated to the father of the first author, João Onofre de Araújo.

Diagnosis. This species is characterized by the male terminalia: hypandrium thin, aedeagus asymmetric with two projections, left blade shape and right with medial projection; parameres paired, asymmetrical and jointed by an unsclerotized dorsal area.

Description. Adult male. Eye bridge with three facet rows, separated at median by almost one facet diameter, interocular suture present, Y-shaped. Four larger supraocular setae alveoli ( Fig. 1 View FIGURE 1–11 ) and two larger setae alveoli on lateroposterior margin of eye ( Fig. 2 View FIGURE 1–11 ). Antenna with scape cylindrical, 1.8 times the length of the spherical pedicel ( Fig. 3 View FIGURE 1–11 ); 14 flagellomeres present; basal flagellomeres fusiform; 13th flagellomere reduced, ovoid, 14th spherical with long apiculus as long as basal bulb of flagellomere; flagellomeres 3–12 with a pair of filiform ascoids, shorter than the flagellomere bearing them ( Fig. 4 View FIGURE 1–11 ). Mouthparts extending beyond basal segment of palpus, labellum with apicolateral bristles ( Figs. 1, 2 View FIGURE 1–11 ). Palpus formula = 1.0:1.5:1.9:2.3, apical segment striated ( Fig. 5 View FIGURE 1–11 ). Wing ( Fig. 6 View FIGURE 1–11 ): radial fork apical to medial fork, radial and medial forks arising basal to apex of CuA 2; R 5 ending at wing tip. Male terminalia (in dorsoventral view): epandrium rectangular, longer than wide, distal margin concave, with lateral stripe of four diagonal setae aveoli on each side; presence of two foramina near proximal margin. Cercus long, 1.5 times the length of epandrium, with one apical tenaculum. Epiproct subtriangular with micropilosity. Hypoproct truncated at apex with apical micropilosity, longer than epiproct ( Fig. 7 View FIGURE 1–11 ). Hypandrium strip-like. Gonocoxite approximately the same length as gonostylus, robust, basally wider than apex, pilose, with small grooves in the base ( Fig. 10 View FIGURE 1–11 ). Gonostylus pilose, cone-shaped wider basally, apex with small seta ( Fig. 8 View FIGURE 1–11 ). Gonocoxal apodeme subtrapezoidal, fused anteriorly ( Fig. 11 View FIGURE 1–11 ). Aedeagus asymmetrical, left blade shape and right with medial projection ( Figs. 8, 9 View FIGURE 1–11 ). Ejaculatory apodeme slightly longer than aedeagus, longer than wide, ellipsoidal. Parameres paired, sclerotized, asymmetrical, jointed by an unsclerotized dorsal area. ( Fig. 9 View FIGURE 1–11 ).
