The western whiptail ("Aspidoscelis tigris") is a small lizard that ranges throughout most of the southwestern United States. Key differences between this species and the Checkered Whiptail ("Aspidoscelis tesselata") are the lack of enlarged scales anterior to the gular fold and the presence of enlarged antebatrachial scales. It was previously known under "Cnemidophorus tigris", until phylogenetic analyses concluded that the genus "Cnemidophorus" was polyphyletic.This lizard is most famous for same-sex reproduction.
