Taxonomic CommentsFrom Crother (2017): Maslin and Secoy (1986) treated the name Aspidoscelis (sackii) innotata as a synonym of A. velox, but Wright (1993, in Wright and Vitt 1993) applied the name A. velox to populations of triploid parthenogens and treated A. innotata as the name of a separate diploid species. Cuellar (1977) found histoincompatibility (rejection of skin grafts) between A. velox-like lizards from Colorado, New Mexico, and Utah, which Cuellar and Wright (1992) interpreted as potential evidence for different ploidy levels. The type locality of A. velox is in Arizona, while that of A. innotata is in Utah, and lizards from New Mexico are known to be triploid (Neaves 1969, Dessauer and Cole 1989). If lizards from the type locality of A. innotata turn out to be diploid, it would be reasonable to recognize a separate diploid species and apply the name A. innotata (Plateau Unspotted Whiptail) to it.
Reeder et al. (2002) examined phylogenetic relationships of the whiptail lizards of the genus Cnemidophorus based on a combined analysis of mitochondrial DNA, morphology, and allozymes. They determined that Cnemidophorus in the traditional sense is paraphyletic and thus in need of nomenclatural revision. Rather than subsume all cnemidophorine species (including Kentropyx) in a single large genus (Ameiva), they proposed a split that placed the North American "Cnemidophorus" clade in the monophyletic genus Aspidoscelis; under this arrangement, South American taxa remain in the genus Cnemidophorus.
Aspidoscelis velox arose through hybridization; parental species were A. inornata and either A. costata or A. burti stictogramma (Moritz et al. 1989).
