简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 16-23; 臀棘 0; 臀鳍软条: 18 - 26; 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) 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). Males with light blue stripes parallel to rays on the basal half of unpaired fins and a black blotch anteriorly bordered by a narrow blue line on posterior portion of dorsal and anal fins. Scales on longitudinal series 26-28, supraorbital neuromasts 16-19, pharyngobranchial teeth 2-5. Dorsal fin origin anterior to anal fin origin in females. Caudal fin rounded.
