Head and pronotum with numerous longitudinal strioles. Elytra with 1 2–13 superficially impressed dorsal longitudinal striae, ending between two thirds and three fourths of elytral length; although 12 dorsal striae being reported in holotype ( Hendrich & Balke 1998 ), in most specimens, an additional short stria presented in basal third of elytra, laterally from stria 12. Median lobe unevenly curved in lateral view; outer margin slightly sinuate, subapically broad, abruptly pointed at apex ( Fig. 19 ). Parameres 'D'-shaped, apex very narrow and long; apical lobes long ( Fig. 20 ). Collecting circumstances.

The species is known so far from only three localities in Maharashtra ( Fig. 45 ).
