Diagnosis

Supraorbital ridge not crenulated. Middle lateral line restricted to caudal peduncle; lower lateral line originating from in front of anal-fin origin to above sixth anal ray. Maxilla extending to below anterior third of eye. Opercular bones with 2 upper and 3 lower spines. Preopercular-mandibular canal not joined to temporal canal. Pelvic fins extending beyond anal-fin origin. In life, pale grey, whitish ventrally. Differentiated by the dorsoventrally oval shape; the prominent distally rounded rostrum, pseudo-rostrum and pseudo-antirostrum; the clearly defined excisura ostii and pseudo-excisura ostii; the acutely constricted collum; and the well developed colliculli.

Ontogeny: The excisura ostii and the pseudo-excisura ostii become deeper and the crista inferior becomes less distinct with an increase in the fish size.
