Here is a photo of a possible E. whitakeri that was posted here a while back. Though I am not sure that E. whitakeri is worthy of full species status.

Note the differences in tail morphology. The individual in the photo has a blunt tail more typically associated with E. johnii, while the individual in the photo has a pointed tail more typically associated with E. conicus.
Personally, I think they are hybrids and until molecular work is done to prove me wrong, that is my opinion.
Cheers,
Chris
