Plocamopherus ceylonicus is very variable in colour, characterized by brown patches and speckling with orange-yellow spots around the edge of the foot and on the mantle. It has three pairs of lateral appendages, the four papillae surrounding the gills are tipped by a large rounded pinkish knob which flashes light when disturbed.
Bill Rudman writes in a comment at Sea-Slug Forum:"Unfortunately, Vallès & Gosliner do not include P. ceylonicus in their review of the genus so I can't comment on their reasons for proposing the new species P. maculapodium. Two other new species in their paper, P. lemur and P. pecoso would also appear to be colour forms of this orange spotted 'species'..."
So Plocamopherus maculapodium, Plocamopherus lemur, and Plocamopherus pecoso are possibly synonyms of Plocamopherus ceylonicus.
