Aspidoscelis is a genus of whiptail lizards in the family Teiidae. The nomenclature for the genus Aspidoscelis was published by T.W. Reeder et al. in 2002. Many species that were formerly included in the genus Cnemidophorus are now considered Aspidoscelis based upon divergent characters between the two groups. The name Aspidoscelis literally means 'shield-leg', from the Ancient Greek aspido- ('shield') and skelos ('leg'). The following species are recognized as being valid. Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Aspidoscelis. In 2011, it was announced that a parthenogenetic hybrid Aspidocelis was bred in the laboratory. This serves as a demonstration of how other hybrid parthenogens in this genus may have arisen.
