Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 18-25; Épines anales 0; Rayons mous anaux: 21 - 27; Vertèbres: 27 - 30. 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.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Niveau trophique (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref.
