Range DescriptionThe range extends from southern Utah, western and central Arizona, southern Nevada, and southern California south to southwestern Sonora and throughout most of Baja California, Mexico (Grismer 2002, Stebbins 2003). Some Arizona populations formerly included in this species are now regarded as X. arizonae and X. bezyi (Papenfuss et al. 2001). A population in northern Durango is now recognized as X. extorrus. See Feldman et al. (2003) for discussion of distribution in the southern Sierra Nevada region of California.
