Cool, I would be interested to hear your reasoning so that I can better identify this species in the future :). What lead to my suggestion of P Spenceri was the pale lateral dorsal lateral stripes and the dotted back pattern.
The other thing to remember with spenceri is that they are out and about on tree trunks and rocks, behaving more like Cryptoblepharus than other members of their genus
I agree with Brian that it is Spencers. I found the images hard to make out, and it was difficult to see the patterns on their back. It is true that they are behaving like Spencers, a species with which I am quite familiar.
