Murdoch, B.D., 2007 (Feb 27) Plocamopherus ceylonicus from Western Australia. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/19497Dear Brent,
I am pretty sure this is a dark form of Plocamopherus ceylonicus. I have just discussed the spheres which are normally found at the tips of some of the four posterior lateral papillae in this species [message #19542]. They seem to be absent in your animal but I can't see the last two papillae clearly enough.
Tantalisingly, there is an earlier message [#18199] from Western Australia of the same species, but again the lateral papillae are out of focus.
Best wishes,
Bill Rudman
