This Phyllidia sp has an interesting coloration that I haven't been able to match in a book. Can you help in identifying this one?

Locality: Lembeh Strait, 55 ft, Indonesia, Celebes Sea, 27 October 2006, Fringing reef. Length: 3 cm. Photographer: Mike Krampf.

Dear Mike,
This is Phyllidia exquisita. One character of this species is that the orange margin to the mantle is only present around the anterior end.  It is interesting to find it associated with an orange sponge. Many phyllidiids are found on orange sponges so its possible that many of them will turn out to be related - but we still have to a lot to do before we can identify the sponges satisfactorily.
Best wishes,
Bill Rudman
