Diagnosis. Disc of pronotum with a band on mid-dorsal longitudinal carina, two oblique bands in prozona that surpass the main transverse sulcus, a horizontal band in the lower margin of lateral lobes of prozona, and posterior border of the pronotum yellow or greenish-yellow ( Figs. 2g , h , and 7a, b ). Prosternal tubercle broad, laterally compressed, with rounded apex. Tegmina with longitudinal and transverse veins yellow delimiting rather large irregular cells with a central dark spot ( Fig. 8k ). Male epiproct rounded with pointed tip, tubercles on posterior margin; furculae prominent, with sharp tips ( Fig. 9a ). Male cerci wide at the base, distal third slightly curved downwards, with truncated apex, surpassing the end of epiproct ( Fig. 9b ). Dorsal valves of aedeagus short, distal third curved downwards, apex acute and weakly sclerotized ( Fig. 10i ). Valves of cingulum subtriangular, with posterior edge prominent ( Fig. 10i ). Cingulum wide V-shaped ( Fig. 11i ). Epiphallus with lophi placed perpendicular to the bridge, with rounded apex, not reaching the posterior processes of the lateral plates ( Fig. 12a ). Redescription and chromatic characters, and material examined . See Appendix 1 Chromatic variation . This species can exhibit variation in body color. Specimens from the northern range of the distribution ( Brazil ) exhibit darker body coloration, from dark green to blackish color. Measurements (in mm). Body length: males: 25.1 (24.5–26); females: 34.5 (27.5–41). Hind femur length: males: 13.3 (13–14); females: 17.9 (16–20). Tegmina length: males: 23.1 (19.5–25); females: 29.8 (27–31). Distribution. This species is found in Argentina (Misiones), Paraguay ( Paraguari , Caaguazú , Amambay , San Pedro , Cordillera ), Uruguay ( Rivera , Paysandú ) y Brasil ( Mato Grosso , Río Grande do Sul ), ( Fig. 13 ).
