Ninth sternum produced anteroventrally; with long, slender, posteromesal keel; produced into thin, long, dorsal plate, filling posterior face of eighth tergum (appearing as a fish-tail shaped structure extending posteriad from posterior margin of eighth tergum in dorsal aspect). Cercus elongate, flared laterad, with an associated basoventral lobe. Tenth tergum with tip entire; with a pointed, dorsal projection, apex hood-like; with many sensillae.
