Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 402); common length : 24.0 cm TL male/unsexed; (Ref. 5450)
soft rays: 12. Body light bluish to greenish dorsally, white ventrally. 3-4 scales on cheek; 19-25 predorsal scales; scaled dorsal and anal fins; Supra-temporal band of scales continuous at dorsal midline. Upper peduncular scale rows usually 11 (11-12); lower peduncular scale rows usually 15 (14-15). A small process on basioccipital for attachment of Baudelot's ligament.
