背棘 (总数) : 16 - 18; 背的软条 (总数) : 7 - 10; 臀棘: 8 - 9; 臀鳍软条: 6 - 8; 脊椎骨: 26 - 27. Midlateral stripe prominent, vertical bars less intensive; black spots in dorsal, anal, and caudal fin; dark spots on the opercle and anterior flank scales. Distinguished from both C. facetum and C. tembe by having 8-9 anal-fin spines [vs. 6-7 (rarely 5 or 8), 5-7, respectively], 13-14 anal pterygiophores (vs. 12-13, 11-12, respectively), modally 17 dorsal-fin spines (vs. 16), and modally 6 gill rakers on first ceratobranchial (vs. 8, 7-8, respectively). Further distinguished from 'C.' facetum in having 14 caudal vertebrae (vs. 13) and from 'C'. tembe by a shorter caudal peduncle including only one or no vertebral centrum (vs. 3). Jaw teeth lack the second cusp (also in tembe vs. present in facetum (Ref. 51414).
