''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 as a genus in its own right. ==References==
