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 ...
Three subspecies have recently been recognized as distinct species by some authorities: [6] Crater chipmunk, Neotamias cratericus, split from N. amoenus [7] Coulee chipmunk, Neotamias grisescens, split from N. minimus [7] Sierra del Carmen chipmunk, Neotamias solivagus, split from N. durangae [8]
A small species, it reaches about 30 cm (12 in) in length including the tail, and a weight of 66–150 g (2.3–5.3 oz). [15] It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail.

The Uinta chipmunk [1] or hidden forest chipmunk [2] (Neotamias umbrinus), is a species of chipmunk in the family Sciuridae.It is endemic to the United States.Formerly known as Tamias umbrinus, [1] phylogenetic studies have shown it to be sufficiently distinct from the eastern chipmunk as to be placed in a separate genus, Neotamias. [3]
[3] [4] Tamias sibiricus is able to survive in various environmental conditions, anywhere from 29°N to 69°N and −65 °C to 30 °C. However, this species has a low ability of dispersal, and since they are mainly introduced into woody forests or urban areas with greenery, they have less potential to be naturally dispersed to other regions.
The same nine subspecies are listed in the 2016 Handbook of the Mammals of the World, [7] but in the ensuing 2020 Illustrated Checklist of the Mammals of the World, the former subgenus Eutamias is promoted to the genus Eutamias, with one extant species (the Siberian chipmunk), and only three subspecies recognized (E. s. sibiricus, E. s. barberi ...
The Sonoma chipmunk (Neotamias sonomae) is a species of rodent in the squirrel family Sciuridae. It is endemic to northwestern California in the United States. [1] Members of Neotamias are characterized by having two premolars. [2] N. sonomae has two subspecies: N. s. alleni and N. s. sonomae. [3]
