Notocitellus

Notocitellus is a genus of ground squirrels, containing two species from Mexico. These species are the tropical ground squirrel (Notocitellus adocetus), and the ring-tailed ground squirrel (N. annulatus). Notocitellus was formerly placed in the large ground squirrel genus Spermophilus, as a subgenus or species group. Since DNA sequencing of the cytochrome b gene has shown Spermophilus to be paraphyletic to the marmots, antelope squirrels, and prairie dogs,[1] it is now separated, along with six other genera.[2] The exact relations of this genus are unclear, though a relation to the antelope squirrels is possible.[2]
