Diagnosis

This species is distinguished by the following characters: body oblong, its depth less than head length and 2.8-3.3 in SL; preopercle rounded, finely serrate, the lower edge fleshy; opercle with 3 flat spines; upper edge of operculum almost straight; 1-3 large canines at midside of lower jaw; gill rakers of first gill arch 7-10 + 15-18 (including 6-87 rudiments on each limb); D IX,13-14; caudal fin lunate, the upper and lower lobes produced, about twice length of middle rays; pectoral-fin rays 16-19; lateral-line scales 66-77; lateral scale series 113-135. Colour of head, body, and median fins yellowish brown to orange-red (specimens from deep water more reddish) with numerous small round or elongate spots of blue, lavender or pink; rear margin of median fins broadly yellow; pectoral-fin rays red to brown, the distal third abruptly yellow[ large juveniles (10-25 cm SL) with irregular black band along dorsal part of body ending below rear of dorsal fin and continuing on head (up to eye) as 3 irregular black spots; black blotch at base of upper caudal-fin rays; head and body (including black band) with small pale blue to pink spots; a pale yellow or white stripe mid-dorsally on head from tip of lower jaw to dorsal-fin origin; small juveniles (< 7 cm SL) lack the black band and black spots on dorsal part of head and body (Ref. 39231, 89707, 90102).
