Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm SL male/unsexed; (Ref. 9774); common length : 20.0 cm SL male/unsexed; (Ref. 9774)
soft rays: 58 - 59. Body brownish, a small dark blotch at junction of straight and curved parts of lateral line. Body deep ovoid, its depth 1.8 to 2 times in SL. Head length 3.1 to 3.3 times in SL. Upper-eye diameter 5.3 to 5.9 times in head length. Maxilla extending to below posterior margin of lower eye. Upper-jaw length 2.3 to 2.4 times in head length. Teeth in upper jaw small and close-set laterally, and enlarged anteriorly. Teeth in lower jaw stronger and more widely spaced than those of upper jaw.
