Platydorid from Lembeh St, Indonesia

Dear Mr. Rudman
In the last four years my husband and I found in the Lembeh strait a variety of nudibranchs, we could not identify. This huge Platydorid (about 18 cm) that we saw in 2005, is one example. This year we found a second specimen with same pattern but about half the size. Both specimen were found and were active at night. I wonder whether it can be grouped into Platydoris speciosa or Platydoris ellioti?
Locality: Nudi Falls, Lembeh strait, 13m, N-Sulawesi Indonesia, Pacific, August 2005, rubble and sandy areas. Length: about 18 cm. Photographer: Heidi Hösel.
Thank you for your help in advance

Platydoris ellioti and P. speciosa are the same species. However I am afraid that there are a number of these large species of Platydoris with a very similar brown mottled mantle. I suspect your animal is Platydoris inframaculata rather than P. ellioti, but the only way to be sure is to look at the colour pattern of the underside of the mantle - and that's not possible with a photo.
Best wishes,
Bill Rudman
