Comments

Taxonomy
This species was formerly included in the genus Spermophilus with about 40 other species. Recent molecular phylogenetic studies suggest that the genus should be split. In 2009 it genus was split into eight genera. Acceptance of the reordering is not universal. ITIS37, NCBI34, and NatureServe72 list the name as Ictidomys tridecemlineatus. GBIF29 refers to this species by its old name, Spermophilus tridecemlineatus. Wilson & Reeder’s Mammal Species of the World places it in the subgenus Ictidomys within the genus Spermophilus, thus retaining its old binomial.
