Pseudanthias rubrizonatus males are pinkish to pinkish orange at the anterior end of the body and are frequently bright yellow on the posterior of the body and on the tail, these two areas being separated by a wide red, vertical bar.

There is a lilac coloured stripe which runs from below the eye to the lower part of the base of the pectoral fin.

The females are reddish-pink, paler ventrally, and each scale has a dark spot in it.

[3] Pseuadanthias rubrizonatus is found at depths of 3 to 152 metres (9.8 to 498.7 ft),[1] in aggregations around isolated coral heads and patches of rubble.
