The new taxon can be distinguished from C. bifasciata Neef de Sainval and Lander, 1993 by its wider and more robust body; elytral color bluish black with two yellow fasciae, the anterior one broadest, reaching suture, at lateral margins extending anteriorly and covering part of humerus, and elytral apices with three strongly developed spines.
