Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 90102); common length : 11.4 cm SL male/unsexed; (Ref. 37816)
soft rays: 12 - 13. Body bluish or reddish dorsally, lighter ventrally. 4-5 cheek scales; 23-30 predorsal scales; scaled dorsal and anal fins; confluent Supra-temporal band of scales at dorsal midline. Upper peduncular scale rows 12-14; lower peduncular scale rows usually 16-17 (15-17). Post maxillary processes 2; posterior end of maxilla tapered. A small flat process on either side of ventrolateral surface of basioccipital, projection not ventrally far from ventral rim of condyle (Ref. 1723). Caudal fin lobes with dark tips.
