Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 10; Anale stekels: 3; Anale zachte stralen: 8. 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).
Body shape (shape guide): short and / or deep; Cross section: compressed.
This species is more likely to inhabit the somewhat shallower coastal waters around its area of occurrence than other Polysteganus which have been trawled deeper than 200 m (Ref. 106993).
