Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 402)
(total): 10 - 11;
soft rays: 11 - 13. Body light blue to brownish dorsally, white to pinkish ventrally. Broad yellow stripe just under lateral line (Ref. 48636). 4-5 cheek scales; 21-27 predorsal scales; scaled dorsal and anal fins. Upper peduncular scale rows usually 11 (11-13); lower peduncular scale rows usually 15 (14-17). Ventrolateral surface of basioccipital with a broad process for insertion of Baudelot's ligament.
