Description. Coloration (specimen preserved in 70% ethanol). Body generally strong yellow orange (68), near carinae and abdomen dorsally in deep yellowish brown (75), contrasting with regions of brilliant yellow orange (67) on mesonotum, and light-yellow orange (70) on legs and abdomen ventrally. Tegmina hyaline with very light gray (93) diffuse spots.
Body length. Male. 3.1–4.0 mm (n = 9); Female. 3.8–4.0 (n = 8).
Head. Vertex ( Figs. 15A, C View FIGURE 15 ): approximately 2.0 times wider (0.4) than long (0.2); apical compartment small and laterally narrow, approx. 2.5 wider (0.2) than medially long (0.08); apical transverse carina (0.253) slightly larger than the subapical carina (0.228); angle formed by the caudal margin concave. Frons ( Fig. 15B View FIGURE 15 ): approx. 1.3 times longer (0.8) than wide (0.6), and approx. 3.0 times wider medially than apically (0.2); anterior region of the frons narrows laterally and weakly concave apically. Frontoclypeal suture, convex, evanescent close to the lateral carinae. Postclypeus ( Fig. 15B View FIGURE 15 ): compressed laterally, median carina moderately developed. Anteclypeus ( Fig. 15B View FIGURE 15 ): median carina well developed from the second half distally of suturing anterior to the clypeus. Rostrum reaching or surpassing slightly the middle of the abdomen.
Thorax. Pronotum ( Fig. 15A, C View FIGURE 15 ): submedian carinae weakly developed, evanescent behind the eyes; hind margin obtusely angled. Mesonotum ( Fig. 15A View FIGURE 15 ): Median carina well-developed, but evanescent distally; lateral carinae strongly developed. Tegmina (forewings) ( Figs. 15D View FIGURE 15 ): length 5.6 mm; hyaline with light gray spots, three spots on the basal cells distinguishable as follows: one on the Pcu + A1 fork, between CuP and A2; another spot occurs on C5, between CuP and MP; a third larger and curved spot occurs over mc, rc and C1, between Cua1 and ScP+RA; three cross spot occur in pcc; r-m1 and mcu-1, occurring distally to the first MP fork; m-cu1 occurs proximally the first MP fork; petiole in RP2.2+RP2.3 weakly developed; simple tubercles in all veins; 12 apical cells; 7 subapical cells.
Posterior legs. Hind tibia ( Fig. 15E View FIGURE 15 ): approximately 2.1 mm; with 6 lateral spines, 3 closest to the femur being small. 1 st tarsomere ( Fig. 15F View FIGURE 15 ): 7 apical teeth of approx. the same size, one lateral larger. 2 nd tarsomere ( Fig. 15F View FIGURE 15 ): 8 apical teeth, the outer 2 larger and the middle ones smaller; 3 thin setae, one separated by apical teeth without setae.
Male terminalia. Pygofer ( Figs. 16A–C, G View FIGURE 16 ): bilaterally symmetrical; in lateral view medially larger; in ventral view, ventromedian process triangular, as wide as tall. Anal tube ( Figs. 16A–C View FIGURE 16 ; 17A–B View FIGURE 17 ): weakly asymmetrical bilaterally; in lateral view, dorsal margin with two convexities, and one smaller concavity apically; ventral margin moderately curved; in dorsal view, wider at the distal margin than at the base; thick distal margin; epiproct triangular moderately developed, flattened dorsoventrally; paraproct long, approx. 3.0 times longer than epiproct, flattened dorsoventrally, wider below epiproct. Genital styles ( Figs. 16A–C, G View FIGURE 16 ; 17C–E View FIGURE 17 ): in lateral view, wide in the apical region and narrow near the base; rounded distal margin apically. Aedeagus ( Figs. 16D–F View FIGURE 16 ; 17F–H View FIGURE 17 ) tubular, asymmetrical. Shaft of the aedeagus with three spines; in right lateral view, with two movable spines, 1 st spine long and bifid (a), occurs apically on the shaft, towards to ventral region, with fork distant of the base; 2 nd spine well elongated (b), occurs apically towards below the flagellum; in left lateral view, 3 rd spine conspicuous (c), semicircular near the apex of the shaft. Aedeagal shaft with four ventral ridges, three rounded and one distinct; in right lateral, rounded ridge larger, and distinct ridge sharp (triangular), occurs medially on the shaft; in left lateral a moderately small and rounded ridge occurs; in ventral view with a small almost straight ridge. Flagellum, thin and without spines, wider, and apically curved.
Female terminalia. Anal tube ( Figs. 18A, C View FIGURE 18 ): in lateral view, rounded and larger distally with lateral margin well developed; in dorsal view, basally excavated and apically swollen; in ventral view, medially carinated and laterally excavated; epiproct and paraproct flattened dorsoventrally and not developed as in the males; in dorsal view, paraproct weakly wide, apically straight, and laterally rounded. Gonocoxae VIII ( Figs. 18A–B View FIGURE 18 ): truncated, in caudal view smaller apically; in lateral view, lateral carinae evanescent near to the base. Ovipositor ( Figs. 18 View FIGURE 18 A-B): in lateral view, sabre-shaped, curved upwards dorsally, surpassing the anal tube.
Etymology. The specific epithet minuta comes from Latin and means small or diminutive and refers to the reduced size of P. minuta sp. nov.
Diagnosis. P.minuta sp. nov. can be distinguished from other species of the genus Pintalia mainly by components of the male terminalia, as aedeagus with a conspicuous spine, well curved - "C" shape- laterally on the apex of shaft of the aedeagus and three small ventral ridges medially.
Distribution. BRA, MG; Itabirito municipality MP8 cave, (Type locality), and Mariana municipality.
