Short description

Dorsal spines (total): 14 - 17; Dorsal soft rays (total): 8 - 10; Anal spines: 3; Anal soft rays: 7 - 8. Diagnosis: body elongate, moderately compressed, its depth 28.4-36.8% of standard length; head length 27.8-34.5% of standard length; 4-5 rows of monocuspid teeth in jaws; dorsal fin usually with spots or bands, dark posteriorly; lower part of body often reddish in life (Ref. 53405). Description: pharyngeal jaw teeth bicuspid; no micro-gillrakers; scales cycloid (Ref. 53405). Coloration: live: males: dark olivaceous-green above, with dark, grey longitudinal band running from eye to posterior part of dorsal-fin base; another dark grey horizontal band extends from snout to hind margin of caudal fin; lower part of body light olivaceous-green, belly pinkish; 2 narrow, dark grey cross bars on upper part of head and another at level of lower lip; opercular region olive-green, with golden reflections and metallic, copper-red to black spot, edged with bright green ventrally; dorsal fin hyaline except for black area behind dark red distal margin, with light blue submarginal band; pectoral fins hyaline except for some traces of olive-green at base and light violet near hind margin; pelvic fins violet, with black anterior margin and bright blue submarginal band; anal fin violet and black-edged; caudal fin violet above horizontal band and olive-green or orange below; upper caudal margin dark red, with dark orange submarginal band; sometimes 1 (rarely more) round, black, orange-edged spot on upper part of caudal fin (Ref. 53405). Females: horizontal bands on body darker grey than in males; dorsal fin lacking red and blue margins which are replaced by narrow black band; posterior black area subdivided into several irregular black zones or occasionally substituted by 1-2 round, black spots; pectoral fins hyaline; pelvic fins light pink rather than violet, and with blue and black margins; caudal fin lacking orange-red margin which is replaced by golden spots; upper part of caudal fin sometimes with 1 (or several) round, black spots bordered by golden area (Ref. 53405).
