Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 4329)
soft rays: 8 - 9. Lacks opercular spines (Ref. 31632). Membranous edge at upper border of the gill cover is well developed. Caudal peduncle elongated, body not deep (Ref. 31632). Pyloric caeca 10-14. Preserved specimens are brownish to yellowish in color, dorsally darker. Numerous brown-black melanophores on scale pockets.
