Ninth sternum greatly produced anteroventrally; with elongate, posteromesal keel; produced dorsally into a thin, broad plate beneath mesal brushes of eighth tergum and with dorsolateral angles produced anteriad between the lateral lobes and the mesal plate of the eighth tergum. Cercus elongate, flared laterad, rounded apically. Tenth tergum with tip entire, apex rounded, arched, with a dorsal knob at midlength; with many sensillae.
