Let me quote the description of Plocamopherus maculapodium from IPN at page 107:
"Red body color, speckled with minute white dots. The name derives from the few larger black spots on the sides of the animal at the base of the foot. Three pairs of short lateral appendages, with the last pair having a prominent, rounded globular structure that is white or pinkish in color."
The above specimens lack the red/brown/black spots at the base of the foot. I misidentified the pictures #1 and #2 and posted them on 25 December 2003
as Plocamopherus imperialis Angas, 1864, which is endemic to New Zealand and South East Australia, I realized my error and changed it on
11 November 2009 into Plocamopherus ceylonicus (Kelaart, 1858) [Polycera].
I changed it again on 25 November 2014 into Plocamopherus cf. maculapodium Vallès & Gosliner, 2006
Bill Rudman writes in a comment at the 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'..."
That is Plocamopherus maculapodium is possibly a synonym of Plocamopherus ceylonicus, I will keep it until this species is formally synonymized.
