This species is distinguished from its congeners by the following set of characters: scale rows above lateral line 6½ and between 5th dorsal-fin spine base and lateral line 4½; pored lateral-line scales 49; suborbital depth is clearly less than orbit diameter (OD), 60% OD; without lines of blue spots on body; dorsal-fin rays are reddish pink but yellowish membranes of both pinkish dorsal-fin and caudal-fin fin lobes; absence of blue iridescence on body but bright whitish iridescence on each body scale of lateral side of bright pinkish body; deep body 43% SL; without bony bulge before and above eye; pinkish upper and lower caudal-fin as well as rear pinkish margin of the caudal fin with yellowish hyaline membrane of most of caudal fin with no whitish upper and lower margins; rear margin of membrane of branchiostegal rays is yellow, with yellow hue on some body scales just above upper pectoral-fin base; caudal fin is moderately forked (Ref. 106993).
