Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9895); common length : 12.5 cm TL male/unsexed; (Ref. 9895)
soft rays: 72 - 78. Dorsolateral line usually undulating. No dark blotches or irregular cross bands on body. Eyed-side lower jaw with crenulate fleshy ridge comprised of several folds, or jaw with a single broadly triangular-shaped fleshy ridge (Ref 9895).
