Range Description

This species is endemic to the southwestern United States. The range includes only a small area in Arizona; a recent taxonomic change that recognized X. arizonae as a distinct species and that described a new species (X. bezyi) in Arizona (Papenfuss et al. 2001) did not precisely define the range of X. arizonae. A phylogeographic analysis of Xantusia by Sinclair et al. (2004) determined that X. arizonae has a smaller range than depicted by Stebbins (2003).
