背棘 (總數) : 0; 背的軟條 (總數) : 18 - 24; 臀棘: 0; 臀鰭軟條: 23 - 30; 脊椎骨: 27 - 30. Two apomorphic color patterns, body bright gray with dark gray to black stripes in males (versus light gray or no stripes; stripes narrower than interspaces) and a vertically paired black blotch on caudal peduncle of juveniles and females (versus small spots irregularly arranged, or a single round dorsally positioned spot, or no spots on caudal peduncle).
