Anterior frontal fovea round, posterior frontal elongate. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 3g ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe longer than parameres, bearing one branch from base ( Fig. 4g ). Phallobase of median lobe asymmetrical and triangular ( Fig. 4g ).
