Distribution

This species was described from Botany Bay, Sydney, Australia. It has subsequently been reported from western Australia, Singapore, Hong Kong, and Tasmania.^[2]

Description

This dorid nudibranch is red, and the dorsum is covered with caryophyllidia; it is very similar to other species of Rostanga.^[1]

Ecology

This nudibranch is found on a colony of the red sponge, Antho chartacea (family Microcionidae) on which it presumably feeds.^[1] Most other species of Rostanga also feed on sponges of the family Microcionidae.
