Pintalia ustulata Stål, 1862

( Figs. 1 I , 10 A–D , 11 I )

Type material. Holotype ♀. Brazil ( RJ); ( NHRS-GULI000075718 ).

Supplementary description. Coloration (preserved specimen). Body mostly dark brown (59), contrasting with some regions of strong brown (55) on the vertex, postclypeus, and legs. Tegmina hyaline with a moderate brown (58) coloration covering the terminal cells, from the pterostigma region to the posterior margin. Deep reddish orange (36) mostly at the base of the antenna pedicels and around (or under) the tegulae.

Body length. Female (examined): 3.9 mm (n =1); 4.0 mm (n = 1) ( Stål, 1862).

Head. Vertex ( Figs. 10B–C ): apical compartment 1.5 to 1.7 times wider than medially long; apical transverse carina and subapical carina medially elongated; apical transverse carina more visible in frontal view, forming a sharp angle in its middle where the frontal median carina is joining; concave caudal margin with small recess medially; basal compartment with median carina reaching the submedian carina. Frons ( Figs. 10A ): 1.1 times longer than maximally wide; approx. 1.5 times wider medially than apically; median carina moderately or weakly developed, touching the apical transverse carina; thin lateral carinae and sinuous in frontal view; anterior region of the frons below the eyes; very low sunk apically. Frontoclypeal suture: semicircular (shallow-open), bent upwards. Post- and anteclypeus: distinct, slightly longer than wide and tubular basally.

Thorax. Pronotum ( Figs. 10B–D ): short, with submedian carina weakly developed and hind margin obtuse. Mesonotum ( Fig. 10B–D ): tricarinate, slightly darker between carinae than laterally; flat in lateral view. Tegmina (forewings) ( Figs. 10E , 11 I ): length 5.4 mm; approx. 2.5 times longer than wide; hyaline, uniform coloration without conspicuous spots; fork of ScP+ RA and RP, at the same height or slightly forward of forks CuA1 and CuA2; r-m1 occurring proximally of the first MP fork; m-cu1 occurs distally of the first MP fork; RP quadrifid; MP 1+2 trifid; MP 3+ MP 4 bifid; simple tubercles in all veins; 12 apical cells; 7 subapical cells; all the nodal cells and narrows before to MP fork, until reaching the costal margin. Hind wing with RP bifid, MP trifid with petiolate anastomosis in MP 3+4 + CuA1 distally forked (Y-type), CuA1 and CuA2 bifid.

Posterior legs. Hind tibia: without lateral spines and 6 apical spines.

Female terminalia. Anal tube moderately small, approx. 1.2–1.4 times longer than wide; in dorsal view elevated medially and with two “grooves” laterally. Gonocoxae VIII, in caudal view rounded slightly larger apically, with lateral margins rounded and elevated. Ovipositor in lateral view, sabre-shaped, curved upwards dorsally.

Diagnosis. P. ustulata can be distinguished from other Pintalia species by the tegmina with by the darkened apical cells and the remaining hyaline tegmina pale. Apical transverse carina and submedian carina medially elongated and apical transverse carina better visible in frontal or dorsofrontal view of the head. In lateral view, head with fully convex margins, from the vertex to the postclypeus.

Distribution. The only location reported by Stål (1862) is Brazil and Rio de Janeiro State (type locality).
