It is common in Indonesia and occurs from Malaysia to the Solomon Islands.

[2] This nudibranch has an orange-brown dorsum interrupted by large white or grey, compound, stalked tubercles.

There are four black rings surrounding tubercles which are placed symmetrically in the middle region of the back.

A single tubercle in front of the rhinophores is also surrounded by a black ring.
