Dorsal spines (total): 7; Dorsal soft rays (total): 9-10; Anal spines: 1; Anal soft rays: 8. The species is characterized by the absence of scales on the cheek, opercle and midline of the nape; fifth pelvic fin ray branched sequentially once; a moderate interorbital trench; a short and narrow postorbital trench; color of living specimens red with a white belly, a large brown-black spot larger than the eye immediately above the pectoral fin base and numerous smaller dark spots across the nape; and in preserved specimens the dark spots remain but the ground color is yellow.
