Spermophilus

Thirteen-lined ground squirrel Spermophilus tridecemlineatus, photographed by Mnmazur.


Belongs within: Marmotini.

Spermophilus, the ground squirrels, has been recognised as a genus of about forty species found in northern Eurasia and North America. However, the genus in this sense may be paraphyletic to other genera in the Marmotini, and recent authors have restricted it to a group of western Eurasian species.
