Pintalia obscuripennis Stål, 1862

( Figs. 1 F , 8 A–D , 11 F )

Type material. Holotype ♀. Brazil ( RJ); ( NHRS-GULI000075715 ).

Supplementary description. Coloration (preserved specimen). Body mostly deep orange yellow (69), contrasting with some regions of moderate orange yellow (71) on the vertex and legs. Tegmina hyaline, deep orange yellow (69) and strong brown (55) on margins, without evident spots, clearer costal margin at the level of the pterostigma.

Body length. Female (examined): 4.0 mm (n =1); 4.3 mm ( Stål, 1862).

Head. Vertex ( Fig. 8B–C ): apical compartment 2.5 to 2.8 times wider than medially long; apical transverse carina almost straight; subapical carina slightly concave; caudal margin concave. Frons ( Fig. 8A ): 1.1 times longer than maximally wide; approx. 1.6 times wider medially than apically; median carina moderately or weakly developed, apically y-shaped forming a triangular region apically along with the apical transverse carina; thin lateral carinae; anterior region of the frons trapezoidal, and straight apically. Frontoclypeal suture: semicircular, bent upwards. Post and anteclypeus: median carina well developed.

Thorax. Pronotum ( Figs. 8B–D ): short, with submedian carina moderately developed; hind margin obtusely angulate. Mesonotum ( Figs. 8B–D ): tricarinate; flat in lateral view with inclined distal region. Tegmina (forewings) ( Figs. 8 D , 11F ): length 7.2 mm; approx. 2.5 times longer than wide; uniform color, no contrasting dark spots; fork of ScP+ RA and RP, little ahead of forks CuA1 and CuA2; parallel r-m1 and mcu-1, occurring distally of first MP fork; RP quadrifid; MP 1+2 trifid; MP 3+ MP 4 trifid; simple tubercles, in all veins; 12–13 apical cells; 7 subapical cells.

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

Female terminalia. Anal tube small, wider than long, and cylindrical. Gonocoxae VIII truncate, in caudal view with lateral margin almost straight and moderately elevated. Ovipositor in lateral view, sabre-shaped, curved upwards dorsally.

Diagnosis. Pintalia obscuripennis can be distinguished from other species of the genus Pintalia by uniform coloration (varying little), and opaque tegmina without conspicuous dark spots, and Cua1 trifid.

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