背的软条 (总数) : 9 - 10; 臀鳍软条: 9 - 11; 脊椎骨: 25 - 27. Distinct dorsal-body surface, which is highly convex before the dorsal fin but changing abruptly at the dorsal origin into a deep, postdorsal concavity most developed in breeding males; absence in nuptial males of distinctive yellow or orange pigment on either the caudal fin or peduncle; weak development of lepidodonts and modally six preopercular pores (Ref. 43452).
