There is a long, robust spine at the angle of the preopercle with vertical margin serrated. To the rear of the bone below the eye there are 2 large, rear-pointing spines and a series of smaller spines on the preopercle and on the opercle. It has a mainly blue body with the head and dorsal region being bright, golden yellow.

It also has a blue ring around the eyes. The caudal and the anal fins are dark blue marked with many black spots. The dorsal fin contains 14-15 spines and 15-16 soft rays while the anal fin has 3 spines and 17 soft rays. This species attains a maximum total length of 7.5 cm.
