The body is a translucent brownish colour with irregular patches of opaque white which merge into an irregular, but perhaps symmetrical pattern, down the dorsal surface of the body. There are also scattered white spots of various sizes down the sides of the body. The extra-rhinophoral and extra-branchial appendages are described as 'white with pale yellow apices on the extra-branchial appendages'. The rhinophores and gills appear translucent white with reddish brown edging.

The species is known from a single specimen 7 mm long alive.
