Dear 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
