Head larger, its length contained 2.3-3.3 times in standard length. Preopercle with 1-3 strong antrorse spines on lower edge; middle opercle spine not reaching edge of operculum. Front nostrils variously shaped, but always closer to rear nostrils than to upper lip. Supramaxilla absent. Teeth fixed (not depressible).
