SSAR 9th Edition Comments:
After earlier studies (Trépanier and Murphy, 2001, Molecular Phylogenetics and Evolution 18: 327–334; Gottscho et al., 2017, Molecular Phylogenetics and Evolution 106: 103–117) suggested that populations of Fringe-toed Lizards from the Mohawk Dunes (Yuma Co., AZ) formerly considered part of U. rufopunctata constitute a separate species, DeRycke et al. (2020, Zootaxa 4778: 67–100) presented additional morphological and molecular data and results corroborating that inference and named the species. (de Queiroz, Kevin and Lauren M. Chan. 2025. Squamata (excluding snakes) – Lizards. Pages 23-37 in Kirsten E. Nicholson (Editor), Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with Comments Regarding Confidence in Our Understanding, 9th Edition.

Taxonomic Etymology:
Honoring a field biologist involved in its discovery.
Uma — An arbitrary name coined by Baird in 1859, possibly derived from Native American sources or used for its brevity. Its etymological origin remains unclear.
thurmanae — A patronym honoring Kayla Thurman, one of the field researchers who helped collect and describe the species in southeastern California. The name uses the feminine genitive suffix -ae.
