Eyes prominent and subcircular, not reaching the level of vertex in lateral view. Frons straight, union frons-fastigium rounded. Median dorsal carina of pronotum slightly marked on metazona, cut by two transverse sulci; transverse sulci deep on dorsum and laterally. Metazona slightly longer than prozona. Anterior pronotal margin straight or notched; posterior margin of disk angulated with pointed apex. Integument of prozona slightly foveolate on dorsum; slightly impresso-punctuate in lateral lobes, integument of metazona rugose. Prosternal tubercle prominent with rounded apex. Tegmina and wings surpassing the tip of the abdomen, with rounded apices. Tegmina with prominent and irregular transverse veins. Hind femur robust. Cerci down-curved with blunt/truncate apex, wide at base, distal third with upper margin rounded and lower margin slightly concave, surpassing the tip of epiproct. Epiproct sub-triangular with pointed apex, median groove deep, tubercles on posterior half, furculae prominent, with subacute tips. Phallic complex: dorsal valves of aedeagus short, strongly down-curved. Valves of cingulum subtriangular, with anterior margin of apex prominent and posterior margin slightly concave in lateral view.
