Épines dorsales (Total) : 7 - 8; Rayons mous dorsaux (Total) : 7 - 9; Épines anales: 1; Rayons mous anaux: 6 - 9. Depressed head and body; generally pale coloration with 6-7 faint vertical bars and black dots on cheeks. Sexually dimorphic: males with more depressed head and body, a larger mouth, and darker fins. Male with about 40 rounded blackish brown spots on cheeks, usually larger than half of pupil; body with 7 lateral blackish brown bars and several rows of black or brown spots; second dorsal with usually 1 simple and 8 branched rays; anal fin with usually 1 simple and 7 branched rays (Ref. 43281).
