Flat-tailed Horned Lizard
Phrynosoma mcallii (Hallowell, 1852)

Current SSAR Comments:
Gottscho et al. (2024, Molecular Ecology 33: e17308) found subdivision of P. mcalli into genetic clusters on either side of the Colorado River as well as further subdivision of the northwestern cluster by the Salton Sea; however, they considered the differentiation of these clusters insufficient to warrant their recognition as species or subspecies.
