Dear Peter & Bill,

I think the species on Peter's pictures is actually Palio dubia (M.Sars). The Palio nothus I have seen in Denmark have been much darker, with a reticulate pattern of the dark pigment, which as I remember it, was brown rather than green. Unfortunately I did not bring my Danish slides to Thailand, so I cannot check. But have a look at the pictures in Bernard Picton & Christine Morrow's book on British nudibranchs (pp. 76-77).

Thanks Kathe,
I found the literature concerning these two species to be extremely confusing. Certainly most of the illustrations of both species look different from Peter's. It doesn't really look like either of the species as illustrated on Bernard Picton's website at:
Before I change the identification I would welcome some more advice from those familiar with the Atlantic fauna.

Best wishes,
Bill Rudman.
