Spine dorsali (totale): 6; Raggi dorsali molli (totale): 9; Spine anali 2; Raggi anali molli: 9. Diagnosis: 122-140 (generally 125-132) scales in lateral line (Ref. 57401). Sides marked with about 20 dark, largely backwards open chevrons (Ref. 57401), which become less distinct in large specimens (Ref. 5491).
