Body elongate, olive green with white or yellow tubercles and papillae. The lamellate rhinophores and the tripinnate gills are translucent in colour and number up to 5. The turbercles and frontal papillae are pale yellow. Whitish compound papillae are situated on either side of the branchial circlet as well as the median longitudinal, dorsal metapodial papillae.

See Bernard Picton's comments below about the confusion in the literature between this species and Palio nothus (Johnston, 1838).
