背棘 (总数) : 11; 背的软条 (总数) : 16 - 17; 臀棘: 3; 臀鳍软条: 14 - 16. Black spot on upper half of dorsal fin from sixth or seventh to ninth spines. Males have long, upcurved extension of maxillary bone marked with black bands (Ref. 26938). Females appear to lack the long double-banded maxilla, and there is only a single blackish band at the corner of the mouth (Ref. 13442).
