Synonyms. Spermophilus spilosoma.

Spotted Ground SquirrelSpotted Ground Squirrels are common in the basins of New Mexico and Trans-Pecos Texas. They almost never are found in rocky habitats, apparently preferring the more mellow soils away from the mountains and foothills. In Arizona, a large portion of the southeastern sector and much of the northern portion supports the species.

The record from Isleta Cave No. 1 (Harris 1993c) is withdrawn, no voucher having been found.
