Ictidomys parvidens

Ictidomys parvidens is a species of squirrel in the family Sciuridae. All the species of Ictidomys were previously believed to belong to the much larger genus Spermophilus (I. parvidens as a subspecies of Spermophilus mexicanus), 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 a genus in its own right.
