Abstract
We assessed the taxonomic relationships within the genus Uromastyx Merrem, 1820 using morphological and genetic methods, resuilting in the resurrection of the genus Saara Gray, 1845 for Saara hardwickii, S. asmussi and S. loricata and in changes of the taxonomic rank of Uromastyx nigriventris, U. aegyptia leptieni and U. shobraki. A synopsis of all taxa considered to be valid is provided, including differential diagnosis, description and data on their respective distribution. A key for the species of Saara and Uromastyx is presented.
