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).
