Épines dorsales (Total) : 10 - 11; Rayons mous dorsaux (Total) : 11 - 12; Épines anales: 3; Rayons mous anaux: 11 - 12; Vertèbres: 26. This species is distinguished from its congeners from the Indian Ocean and the Pacific Ocean by the following set of characters: body elliptical and elongate in lateral view and compressed; D X-XI,11-12; A III,11-12, anal fin base short 16.9-20.6% SL; total gill rakers externally 15-19, gill rakers on upper limb externally 3-5, gill rakers on lower limb externally 11-15; long caudal peduncle 18.7-26.5%SL (depth 9.9-11.8% SL); total lateral line 55-64, pored scales 44-55, scale rows in longitudinal row 49-57; precaudal- and caudal vertebrae 10+16; pterygiophores, dorsal 21, anal 12; mouth terminal; silvery line under eye, colour silvery to bluish metallic; operculum with a vertical green bar running down rear of preoperculum; dorsal part of body without dark counter-shading; sixth dorsal fin spine length, 8.7-11.9 % SL; body depth, 33.3-41.6 % SL (Ref. 92523).
Maximum length of individuals observed from the wild may be in excess of 52 cm SL (Ref. 92523).
