Pintalia proxima Stal 1862

Pintalia proxima Stål, 1862 (Figs. 1 H, 9 A–D; 11 H) Type material. Holotype ♂. Brazil (RJ); (NHRS-GULI000075717). Supplementary description. Coloration (preserved specimen). Body mostly dark brown (59), contrasting with some regions of light orange-yellow (70) on the vertex, pronotum, tegulae and legs. Tegmina hyaline with stitches over the veins and a large spot starting at the costal margin and covering the mostly distal region in dark brown (59). Body length. Male (examined): 3.6 mm (n =1). Female 4.5 mm (n = 1) (Stål, 1862). Head. Vertex (Figs. 9B–C): apical compartment 2.8 to 3.0 times wider than medially long; apical transverse carina slightly concave, almost straight; subapical carina slightly arched, slightly concave, and asymmetrical; concave caudal margin with small basal emargination. Frons (Fig. 9A): approx. 1.2 times longer than maximally wide; approx. 1.5 times wider medially than apically; median carina moderately developed, evanescent basally, slightly y-shaped apically; thin lateral carinae; anterior region of the frons trapezoidal, almost straight apically. Frontoclypeal suture: straight bent upwards. Post-and anteclypeus: median carina well developed. Thorax. Pronotum (Figs. 9B–D): submedian carina moderately developed and hind margin obtusely angled or rectangular. Mesonotum (Figs. 9B–D): tricarinate; lateral margins darker than between the carinae; flat in lateral view with distal region inclined. Tegmina (forewings) (Figs. 9D, 11H): length 6.0 mm; approx. 2.8 times longer than wide; hyaline with a conspicuous spot that covers all the nodal cells and narrows in the prenodal area, until reaching the costal margin; ScP+RA and RP, ahead of forks CuA1 and CuA2; r-m1 and mcu-1 occurring distally of first MP fork; m-cu1 occurs proximally r-m1; RP quadrifid; MP1+2 trifid; MP3+MP4 bifid; simple tubercles throughout all the veins; 12 apical cells; 7–8 subapical cells. Posterior legs. Hind tibia: 1 lateral spine and 6 apical teeth. Diagnosis. P. proxima can be distinguished from other species of the Pintalia genus by the tegmina with radial cells distinct, in the transverse direction, with a conspicuous spot that covers all the nodal cells and narrows before to MP fork, until reaching the costal margin. Distribution. The only location reported by Stål (1862) is Brazil and Rio de Janeiro State (type locality).

Body mostly dark brown (59), contrasting with some regions of light orange-yellow (70) on the vertex, pronotum, tegulae and legs. Tegmina hyaline with stitches over the veins and a large spot starting at the costal margin and covering the mostly distal region in dark brown (59). Body length. Male (examined): 3.6 mm (n =1).
