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).
