The Pearly Wrasse can be recognised by its colouration. Females are brown-green to pinkish above and pale below. They have white blotches on the sides and a pink region on the rear of the abdomen. There is a black spot behind the eye and another on the upper "corner" of the operculum. The middle of the dorsal fin has a yellow or blue-rimmed ocellus. Males are green with orange-red spots. They lack the white and red markings of females.
The species grows to 12.5 cm in length.
It can be distinguished from the similar-looking Cloud Wrasse, by the shape of the band across the cheek. In the Pearly Wrasse the band rises posteriorly, but in the Cloud Wrasse it descends posteriorly.
It is known from tropical marine waters of the Central and Western Pacific. In Australia it occurs off north-western Western Australia and from northern Queensland to coastal northern New South Wales.
