Chipmunks are classified as four genera: Tamias, of which the eastern chipmunk (T. striatus) is the only living member; Eutamias, of which the Siberian chipmunk (E. sibiricus) is the only living member; Nototamias, which consists of three extinct species, and Neotamias, which includes the 23 remaining, mostly western North American, species.
Caged Tamias chipmunk, Tokyo area. The genus Tamias was formerly divided into three subgenera that, in sum, included all chipmunk species: Tamias, the eastern chipmunk and other fossil species; Eutamias, of which the Siberian chipmunk (E. sibiricus) is the only living member; and Neotamias, which includes the 23 remaining, mostly western ...

The genus is often treated as a subgenus of Tamias, which is now restricted to the eastern chipmunk of North America. [1] Neotamias, which now includes the western North American chipmunks, has also been included in Eutamias. [2] In addition to the Siberian chipmunk, several fossil species have been assigned to this genus:
This western American dweller is the largest of the three species of chipmunks found in the Colorado Front Range (which also include the Least Chipmunk and the Uinta Chipmunk). On average it weighs about 62 grams (2.2 oz). Chipmunks are distinguished from ground squirrels in that their faces have a stripe going across under the eye.
