The Spanish sand racer (Psammodromus hispanicus) has been recently split into three distinct species: P. hispanicus, P. edwardsianus, and P. occidentalis. Some morphological differences have been reported but there is as yet no description allowing unambiguous identification of the three species. Here, we describe differentiation in body measurements, scalation traits, and colour traits as well as in the degree of sexual dimorphism. Our results show that P. edwardsianus can be easily distinguished by the presence of a supralabial scale below the subocular scale, which is absent in the other two species. Psammodromus hispanicus and P. occidentalis can be distinguished by the number of femoral pores, throat scales and ocelli, and the relative width of the...
