Pintalia inornata Stål, 1862

( Figs. 1 E , 7 A–D , 11 E )

Type material. Holotype ♀. Brazil ( RJ). ( NHRS-GULI000075714 ).

Supplementary description. Coloration (preserved specimen). Body mostly dark brown (59), contrasting with some regions of light orange-yellow (70) on the pronotum, frons laterally, and some regions of the legs. Forelegs light orange-yellow (70), with dark brown stripes (59). Tegmina transparent and smoked, with dark brown (59) veins, without spots.

Body length. Female: 5.0 mm (n = 1) ( Stål, 1862).

Head. Vertex (7B–C): distinct; apical compartment 1.2 to 1.4 times wider than medially long; apical transverse carina elongated medially, more visible in frontal view; subapical carina straight; concave caudal margin; median carina occurs in little more than 1/2 of basal compartment. Frons ( Fig. 7A ): approx. 1.0 times longer than maximally wide; approx. 1.4 times wider medially than apically; median carina moderately developed above the level of the antennae; apically touching the apical transverse carina, evanescent in the basal half near the median ocellus; thin lateral carinae; anterior region of the frons distinct, at same compound eye level. Frontoclypeal suture: semicircular, very curved, bent upwards. Post- and anteclypeus: with median carina well developed, starting at about half the length of anteclypeus.

Thorax. Pronotum ( Figs. 7B–D ): submedian carinae weakly developed; hind margin obtusely angled or rectangular; lighter coloration at the caudal margin and between the eyes. Mesonotum ( Figs. 7B–D ): tricarinate, in dorsal view almost straight and parallel carinae, very flat in lateral view. Tegmina (forewings) ( Figs. 7D , 11E ): length 7.1 mm; approx. 2.5 times longer than wide; transparent and smoked, without spots; C1b exhibit a crossvein; C5 small; fork of ScP+ RA and RP, approx. 2.0 times closer to the basal cell than forks CuA1 and CuA2; r-m1 occurs from the first MP fork; mcu1 occurs distally r-m1 and laterally to MP 3+4; RP quadrifid, RP 2+3 with petiolate anastomosis distally forked; MP 1+2 trifid with petiolate anastomosis in MP 1.1+ MP 1.2; MP 3+4 bifid; simple or inconspicuous tubercles; 12–13 apical cells; 8 subapical cells.

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

Diagnosis. P. inornata can be distinguished from other Pintalia species mainly by the distinct vertex, and in frontal view with median carina of the frons joined to the anterior margin of the vertex in a "y" shape, and petiolate ramifications in the distal veins of RP and MP.

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

Remarks. Emeljanov (2007) described the genus Proclytus Emeljanov, 2007 to allocate a single species from French Guiana, Proclytus guianensis Emeljanov, 2007 . P. guianensis exhibits the vertex like P. consobrina with the apical transverse carina elongated medially, hind tibia without lateral spines. Some specimens identified with Proclytus in the ISLA collection, in addition to the corresponding characters of the head, wings and male terminalia with Proclytus guianensis , also exhibit dark stripes on the forelegs like P. consobrina , which unfortunately cannot yet have the male genitalia verified.
