Texas Alligator Lizard
Gerrhonotus infernalis Baird, 1859 “1858”

Current SSAR Comments:
García-Vázquez et al. (2018, Journal of Biogeography 45: 1640–1652) and Blair et al. (2022, Biological Journal of the Linnean Society 135: 25–39) found deep divergences within G. infernalis in the United States and Mexico. Furthermore, samples of the newly described G. mccoyi (García-Vázquez, 2018, Herpetologica, 74: 269–278) from Coahuila, Mexico are nested within G. infernalis for both mtDNA and nuclear datasets.
