This species is distinguished from its congeners by the following characters: body elongate with greatest body depth 22.6-25.3% SL; D IX,11; A III,12; pectoral-fin rays 13; tubed lateral-line scales 28. Colouration: interspinous membrane between anterior two to three spines of dorsal fin has a black spot; males with head yellow and extensively reticulate; abdominal region behind pelvic and pectoral fins is orange to orange-pink with yellow crosshatch markings; posterior part of body purple black; females are distinctly bicolored, orange-brown dorsally, white ventrally (Ref.
123182
).
Found well above the bottom of exposed seaward reefs (Ref.
9710
) away from lagoons and sheltered bays (Ref.
123182
). Feeds on small invertebrates (Ref.
