背面の脊椎 (合計) : 14; 背鰭 (合計) : 11 - 12; 肛門の骨: 3; 臀鰭: 9; 脊つい: 27 - 28. It is distinguished from all congeners by the presence of a characteristically robust and strongly recurved oral dentition (Ref. 57663). An extremely deep-bodied and robust species, rather less laterally compressed than other members of the genus (Ref. 57663).
