Nudibranch id

Is this a lettuce nudibranch? He is paper thin and about 1.5 inches long. Found him in my refugium today. Hitchhiker.... seems too thin to be a lettuce...

Well, I've narrowed it down to a flat worm. Still not sure what type. There is a picture of it in "Reef Invertebrates" by Calfo and Fenner on page 178 at the top, but it is not labeled with a name... Getting closer.

polyclad?

There are at least 3 similar species of mollusc-eating flatworms, and I'm not sure that all of them have names. One of the similar species is Phrikoceros mopsus. I don't know if yours is that species, but it must be in the same genus if it's not.
