From the valley of Jequetepeque, Peru. 



This species is intermediate between the last described, P. inaqualis, and such 

 species as the P. reissii in the character of the squamation. In the small size of 

 its distal lamina? of the digits, it differs from all the other species, and approaches 

 the Australian genus Stenodactylopsis of Steindachner.
