The Chihuahuan spotted whiptail (Cnemidophorus exsanguis, syn. Aspidoscelis exsanguis) is a species of lizard native to the United States in southern Arizona, southern New Mexico and southwestern Texas, and northern Mexico in northern Chihuahua and northern Sonora. The species is believed to be the result of extensive hybridization between the little striped whiptail, Cnemidophorus inornatus, the plateau spotted whiptail, Cnemidophorus septemvittatus, and the western Mexico whiptail, Cnemidophorus costatus. It is one of many lizard species known to be parthenogenetic.
