Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 15; Anal spines: 3; Anal soft rays: 7. This species has the following characters: color when fresh, dull red on head and body, shading to pale yellow ventrally, bases of median and pectoral fins irregular pale yellow or with white blotches; spinous dorsal fin is pale bluish white, as if daubed with thick paint; upper lip pale, with several red or white vertical bars; iris reddish orange, with short thin radiating blue-grey streaks. D X, 15, the fin margin moderately notched before soft-rayed part, with 3rd spine longest (24-30% SL), 1.8 in head length, short cirrus behind tips of spines 3, 4 and 5; A III,7, with 2nd spine longest, 2nd and 3rd anal-fin rays elongated; pectoral fins 14 rays, all branched except upper and lowermost 2 or 3 rays, fin reaching vertical at 3rd (4th) anal-fin ray; caudal fin slightly emarginate, principal rays 17, branched rays 15, 3 uppermost principal rays slightly produced; pelvic fins not reaching anus. Oval body with depth 2.1-2.5), head length 2.2-2.4, peduncle depth 7.2 (& 7.6) in SL; orbit diameter greater than snout length, 3.8 (3.4), snout length 4.8 (4.4-5.0), bony interorbital width 7.4 (9.8) in head length. Completer lateral-line with 31 (28, 30) tubed scales, 2 rows of large scales between middle dorsal fin spines and lateral-line and 3 scales from dorsal SL; orbit diameter 3.6-3.9, snout length, 4.1-4.8, bony interorbital width 8.0-8.5, all in head length. Lateral line incomplete, ending below middle of soft dorsal fin, with 16-20 tubed scales; 1 row of large scales between 5th dorsal-fin spine and lateral-line; circum-peduncular scales 12; scales on top of head extend to rear nostrils; operculum scaly, with 5-7 oblique series of large scales on cheek and a series along interopercle; snout suborbitals and lower jaw naked. Maxilla reaches past vertical at rear edge of eye; a row of 7-11 small ctenoid scales along (below) dorsal ledge of maxilla. Preopercle edge with 14-20 coarse serrae posteriorly; no antrorse spine on lower edge; subopercle and interopercle with 7-9 coarse serrae. Gill-rakers 4-5 / 9-11. Two supraneural bones, /0+0/2/1+1/1/1/ (Ref. 81822).
