Épines dorsales (Total) : 10; Rayons mous dorsaux (Total) : 10; Épines anales: 3; Rayons mous anaux: 10. This species is distinguished by the following characters: body shape oblong to elongate, SL/BDd ratio 2.7-3.1, forehead prominent; caudal fin is large, moderately forked with a subtle middle notch, its lobes slightly convex inside; flanks silvery; anal fin, caudal fin, dorsal fin, and pectoral fin reddish to red; distinctive dark patch above eye; protruding, large eyes (eye diameter reaching 37-40% of head length) (Ref. 131644).
Cross section: compressed.
Occurrence based on underwater sightings of solitary individuals at ca. 18-25 m depth on the outer slope of the reef off Saint-Gilles on the western coast of Reunion Island, above a bottom constituted by sand, lava boulders, and sparse coral colonies (Ref. 131644).
