Janolus sp from Ningaloo Reef

I think this is a Janolus sp but not sure on a more accurate ID.
This is the first orange one I have seen with such distinctive white markings.

Dear Kristin,
Yes this is a species of Janolus. I have included a close-up of the head alongside to show the characteristic wrinkled ridge [or caruncle] between the rhinophores. Your animal has similarities to the eastern Australian Janolus sp. 1 but that species seems to have many more cerata and they have a white subterminal band. I think I will keep your animal separate as Janolus sp. 9 until someone studies the group.
Best wishes,
Bill Rudman
