I think this might also be P. entrecasteauxii. But yes does look a bit like a delicata. Lacks the usual mid vertebral dark line in guichenoti. I think this might have to go as a skink. Does the photographer have a photograph showng a view down onto the top of the lizard (esp the head)?
I must admit that my first thoughts were entrecasteauxii but I agree, it looks more like delicata. Unfortunately images often miss out on the characters we need to rule out some species. It's often hard enough when you have the darn thing in your hand!
