Ictidomys mexicanus Erxleben, 1777
All the species of Ictidomys were previously believed to belong to the much larger genus Spermophilus, but DNA sequencing of the cytochrome b gene showed that this group was paraphyletic to the prairie dogs and marmots,, and could therefore no longer be retained as a single genus. As a result, Ictidomys is now considered as a genus in its own right (Helgen et al., 2009).
