Description. Male. Body brown with dark brown tegmina. Head subconical, frons distinctly inclined; antenna relatively longer, 1.5–1.7 times longer than length of head and pronotum combined; middle antennomeres 5.0–5.5 times longer than width; scape as long as wide; lateral foveloae rectangular, three times longer than wide; vertical diameter of eye as long as or slightly longer than subocular groove; frontal ridge as wide as scape between bases of antennae, diverged toward clypeal suture; facial carinae distinct. Pronotum with prozona as long as metazona, median longitudinal carina bisected by principle transverse sulcus in mid; lateral carinae gently incurved on prozona, abruptly diverged on metazona; anterior margin of pronotum straight, posterior margin obtusely angulate, slightly granulose posteriorly; lateral lobe of pronotum as long as pronotal length. Mesosternal interspace 1.2 times wider than long. Ventral thorax with numerous white hairs. Tegmina macropterous, surpassing hind knee, not reaching mid of hind tibia; anterior margin with small precostal bulge, tegminal apex widely round; costa and subcosta sinuated (S-shaped); costal and radial areas narrower than subcostal area; medial area wider than cubital area; bright stigma present on third fifths of joining veins composed of media and cubitus. Hind wings smoky. Abdomen with narrower tympanal opening four times longer than width. Hind genicular lobes and knees blackish, hind tibiae reddish. Abdominal sides with black patches basally. Fore femur as long as pronotum. Epiproct triangular, as long as basal width, its lateral margins moderately sinuated, its apex sharply excised.
