Concerning message #16277:
This is a aeolid nudibranch from North Sulawesi, on the stinging hydroid Aglaophenia cupressina.
Locality: Manado, 10, North Sulawesi, Indonesia. Length: 2 cm. Photographer: Francesco Ricciardi.
Is it Cuthona yamasui? It seems to be very very different, but is the only species I found living on this hydroid.

If you do a search on the Forum for Aglaophenia you will see there are a number of nudibranchs which feed on species of this genus of hydroids. Amongst tropical aeolids have a look at Ching Yao Chan's message [#16249] which describes ann animal which is identical to yours. As he suggests, it certainly could be a colour form of Cuthona diversicolor. It will be interesting when someone has the opportunity to study its anatomy.
