A deep-bodied snapper, with head profile straight or convex; preopercular notch distinct and deep; interopercular knob marked, increasing with age until it becomes a short spike in large adults; vertical and horizontal edges of preopercle finely serrated. Dorsal fin with 11 spines and 15 or 16 soft rays; anal fin with 3 spines and 10 or 11 soft rays; soft parts of dorsal and anal fins pointed. Longitudinal scale rows above lateral line appear to rise obliquely to dorsal profile, those below more or less horizontal anteriorly but appearing to rise obliquely posteriorly; scales on head beginning behind eye; soft parts of dorsal and anal fins with a scaly sheath. Colour: deep red in large adults; juveriles and smaller adults pink with a dark red band from first dorsal spine through eye to tip of snout; a second dark band from middle of spinous part of dorsal fin to pelvic fin; and a third band running from base of last dorsal fin spines obliquely downward across caudal peduncle and along lower rays of caudal fin; margin of soft part of dorsal, upper margin of caudal, and anterior rays of anal fins, dark. DISTINGUISHING CHARACTERS OF SIMILAR SPECIES OCCURRING IN THE AREA:

Lutianus malabaricus: no distinct preopercular notch or interopercular knob; dorsal fin rays 14 (15 or 16 in L. sebae); and fin rays 8 or 9 (10 or 11 in L. sebae).
