Two apomorphic color patterns, body bright gray with dark gray to black stripes in males (versus light gray or no stripes; stripes wider than the light 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). Second pharyngobranchial teeth 6-7 and adult males with a rather deep body which sometimes forms a discoid body morphology. Supraorbital neuromasts 16-19, scales on longitudinal series 26-28. Dorsal fin origin anterior to anal fin origin, caudal fin rays 22-25. Caudal fin rounded.
