Duri punggung (Keseluruhan (total)) : 7 - 8; duri punggung lunak (Keseluruhan (total)) : 19 - 21; Duri dubur: 0; Sirip dubur lunak: 14 - 15. Spinous dorsal short with anterior spines longest; caudal slightly rounded; pectorals rounded, lower 8 rays exserted, middle rays lengthened reaching anal insertion; pelvic fins reaching anus (Ref. 6885).
