SSAR 9th Edition Comments:
DeRycke et al. (2020, Zootaxa 4778: 67–100), based on their own results and those of Gottscho et al. (2017, Molecular Phylogenetics and Evolution 106: 103–117), considered the species status of U. rufopunctata to be uncertain. The populations in question may be 1) part of U. notata, 2) part of U. cowlesi (endemic to Mexico), 3) a hybrid swarm between U. notata, U. cowlesi, and lizards from the geographic area between those species, or 4) a species that is incompletely separated from both U. notata and U. cowlesi.
