Description. Coloration (specimen preserved in 70% ethanol). Body generally deep orange (50), contrasting with regions in deep orange (51) on carinae, mesonotum, frons medially and abdomen dorsally, and pale orange yellow (73) on vertex, frons laterally and abdomen ventrally. Tegmina hyaline, with diffuse spots from light grayish yellowish brown (79) to dark grayish yellowish brown (81) from medial to distal region.
Body length. Male. 3.0 mm (n = 1); Female. 2.8–3.8 mm (n = 4).
Head. Vertex ( Fig. 34A, C View FIGURE 34 ): approximately 1.5 times wider (0.3) than long (0.2); apical compartment approx. 3.3 times wider (0.2) than medially long (0.06); apical transverse carina (0.291) larger than the subapical carina (0.242); angle formed by the caudal margin well triangular. Frons ( Fig. 34B View FIGURE 34 ): 1.4 times longer (0.7) than wide (0.5), approx. 1.6 times wider medially than apically (0.3); median carina with two lines side by side that separate near the frontal ocelli and in the anterior region of the frons; anterior region of the frons large and moderately concave apically. Frontoclypeal suture convex, and straight/inclined laterally. Postclypeus ( Fig. 34B View FIGURE 34 ): median carina moderately developed. Anteclypeus ( Fig. 34B View FIGURE 34 ): median carina well developed. Rostrum in ventral view surpassing slightly the base of the abdomen.
Thorax. Pronotum ( Figs. 34A, C View FIGURE 34 ): submedian carina weakly developed; hind margin obtusely angled. Mesonotum ( Figs. 34A View FIGURE 34 ): median carina weakly developed and evanescent distally; lateral carinae moderately developed. Tegmina (forewings) ( Figs. 34D View FIGURE 34 ): length 4.9 mm; hyaline with light gray to dark brown spots, the shape of the spots and veins in parts as in P. pictipennis Stål 1862 , see Remarks; fork of ScP+RA and RP, approx. the same height or a little forward of forks CuA1 and CuA2; parallel r-m1 and m-cu1 occurs distally of the first MP fork; simple tubercles in all veins; short subapical cells (C1b, C2, C3a, C3 and C4); petiole in RP2.2+RP2.3 weakly developed; 12 apical cells; 7 subapical cells.
Posterior legs. Hind tibia ( Figs. 34E View FIGURE 34 ): approximately 1.4 mm; with 6 lateral spines, the four closest to the femur being small or inconspicuous. 1 st tarsomere ( Fig. 34F View FIGURE 34 ): 7 apical teeth of approx. the same size, one being larger lateral. 2 nd tarsomere ( Fig. 34F View FIGURE 34 ): 8 apical teeth, the 2 external ones larger, and the intermediate ones smaller; 3 thin setae, one separated by apical teeth without setae.
Male terminalia. Pygofer ( Figs. 35A–C, G View FIGURE 35 ): bilaterally symmetric; in lateral view, dorsocaudal margin totally convex and larger medially; in ventral view, ventromedian process triangular, as wide as tall. Anal tube ( Figs. 35A–C View FIGURE 35 ; 36A–B View FIGURE 36 ): short and bilaterally symmetric; in lateral view expanded and rounded distally, with two flat and rectangular lateral processes ventrally, dorsally flattened near the base and rounded on the distal margin; epiproct in lateral view, moderately developed, dorsally elevated/swollen; in dorsal view rounded apically; paraproct long and rounded dorsally with curved distal margin; in caudal view approx. with the same wide on the base and to apex. Genital styles ( Figs. 35A–B, G View FIGURE 35 ; 36C–E View FIGURE 36 ): bilaterally asymmetric, in left lateral view short and rounded apically; in right lateral view also rounded but slightly elongated apically. Aedeagus ( Figs. 35D–F View FIGURE 35 ; 36F–H View FIGURE 36 ) tubular, asymmetrical. Shaft of the aedeagus with three spines, two movable and one rigid; in right lateral view, 1 st spine wide (a), occurs apically on the shaft of the aedeagus towards the ventral region of the flagellum; in left lateral view, 2 nd spine small (b), occurs apically on the shaft; 3 rd spine small and rigid, as wide as long (c), occurs below the middle of the shaft; ventral ridge developed dorsally near the base of the shaft, with four conspicuous spines, rigid and short, two closest to the base being larger. Flagellum thin and curved, slightly larger than the shaft of the aedeagus with a small process apically.
Female terminalia. Anal tube ( Figs. 37A–C View FIGURE 37 ): almost as wide as it long and wider towards the base; in dorsal view rounded medially and with lateral margin well developed, but evanescent apically; flat ventrally; epiproct and paraproct weakly developed. Epiproct with elongated base, slightly triangular apically. Paraproct rounded in dorsal view. Gonocoxae VIII ( Figs. 37A–B View FIGURE 37 ): truncated, in caudal view with lateral margin well developed and rounded. Ovipositor ( Figs. 37 View FIGURE 37 A-B): in lateral view, sabre-shaped, curved upwards dorsally, slightly surpassing or no surpassing the anal tube.
Etymology. The specific epithet stali is a tribute to the author Carl Stål, who made major contributions to the knowledge of the Fulgoromorpha and described the genus Pintalia Stål, 1862 .
Differential diagnosis. Pintalia stali sp. nov. can be distinguished from most species of the genus Pintalia mainly by characters of the male terminalia, the anal tube is rounded and expanded distally, with two conspicuous processes flattened in the lateral/ventral region. Aedeagus displays four not-movable spines dorsally on the base of aedeagal shaft. However, this species can be confused with P. pictipennis Stal, 1862 , due to its external morphology, although it exhibits conspicuous characters that allow differentiation, for example: P. stali sp. nov displays on the clavus of the tegmina only a small circular spot over the Pcu + A1 bifurcation, while P. pictipennis displays a large spot that covers almost the entire clavus, and the first bifurcation of ScP+R is slightly in front of the first bifurcation of CuA in P. stali sp. nov., while it is moderately in front in P. pictipennis . Furthermore, the anal tube is also useful to differentiate these species, in P. stali sp. nov. it is almost tubular and approx. 3x wider distally with a pair of flattened processes in the ventrolateral region, while in P. pictipennis it is completely flattened dorsoventrally slightly curved medially, without processes in the ventrolateral region.
