Description. Morphometries presented in Table 1. Body moderately depressed. Head sloped from snout to supraoccipital at approximately 35° above horizontal, supraoccipital and nuchal region slightly elevated, forming a low horizontal ridge back to dorsal-fin origin. Dorsal profile gently sloped down from dorsal-fin origin to posterior insertion of adipose fin, then up along dorsal lobe of caudal fin. Ventral profile flat from snout to anal-fin origin, modestly arched from anal-fin orgin to insertion of ventral unbranched principal caudal-fin ray. Caudal peduncle compressed, ovate in cross section. Body widest at insertion of pectoral-fin spines, narrowest at base of caudal fin. Snout rounded in dorsal view. Eye small (orbit diameter 9.8, 9.1 % HL). Iris operculum absent. Supraorbital regions not elevated. Interorbital surface slightly convex. Infraorbitals, frontal, nasal, pterotic, and supraoccipital supporting odontodes. Preopercle and opercle without odontodes. Evertible cheek plates supporting hypertrophied odontodes that can be everted just short of perpendicular to longitudinal axis. Cheek odontodes 28, 21; longest evertible cheek odontodes not reaching beyond cleithrum. Oral disk covered with papillae; buccal papillae absent
