|Scientific Name:||Aspidoscelis gypsi|
|Species Authority:||(Wright & Lowe, 1993)|
Cnemidophorus gypsi Wright & Lowe, 1993
|Taxonomic Notes:||This taxon was first described as a subspecies of Cnemidophorus inornatus (Aspidoscelis inornata). Crother et al. (2000) and Collins and Taggart (2002) treated it as a distinct species. Samples from Edge of Sands have characteristics that suggest earlier gene exchange with Aspidoscelis inornata llanuras; there is no evidence at present for direct contact between gypsi and llanuras (Wright and Lowe 1993).
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.
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer/s:||Cox, N., Chanson, J.S. & Stuart, S.N. (Global Reptile Assessment Coordinating Team)|
Listed as Vulnerable because it is known from only a single location.
|Range Description:||This species is restricted to a small area in the southwest of the United States. Its range includes the White Sands region, in south-central New Mexico (Wright and Lowe 1993). The White Sands region encompasses about 712 sq. km, and the lizard inhabits only a portion of this area.|

|Population:||The entire range of this species can be regarded as comprising only one occurrence or subpopulation. The total adult population size is unknown but may exceed 10,000 (assuming at least 10 adults per ha [1,000 per sq. km] over at least 10 sq. km; however, density and area of occupancy are unknown). Population trends are unknown but probably stable.|
|Habitat and Ecology:||This lizard is restricted or nearly restricted to dunes of white sand (Wright and Lowe 1993). Dixon (1967) reported finding individuals as far as 50 m from the dunes, on what he called "adobe soil."|
|Major Threat(s):||No major threats have been identified.|
|Conservation Actions:||This lizard occurs on the White Sands National Monument and White Sands Missile Range.|
