Thorax. Pronotum slightly transverse, approximately 1.2 times as wide as long, widest in apical third to half, with longitudinally slight impression in median region; pubescence directed posteriorly in midline; hypomera fully visible in lateral aspect. Elytra slightly transverse, slightly wider than pronotum; elytron approximately 1.7 times as long as wide, pubescence directed posteriorly and postero-laterally; postero-lateral margin almost straight; hind wings fully developed.
