Pronotum with lateral margins of the metazona slightly produced, forming a distinct expansion along its length; walking-leg femora with rounded genicular lobes; subapical margin of forewings with a small but distinct lobe; alae with a triangular apex; genitalia with acute bl, a sinistrally re-curved sdp, a simple, serrated afa, and a large loa consisting of two lobes. Female . Pronotum with teeth along margin of the metazona; walkingleg femora with acute genicular lobes.
