Systematics, Phylogeny, and Evolution of Phrynocephalus (Superspecies przewalskii ) (Reptilia: Agamidae)

The superspecies przewalskii group of Phrynocephalus includes several taxa with unclear taxonomic status. We analyze a fragment of the mitochondrial DNA gene COI and the body patterns of 275 specimens including type specimens. The results resolve the taxonomy and phylogeny of the group and we provide a diagnostic key for the species.
