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]
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 ...
Distribution of Tamias striatus subspecies in the Door Peninsula vicinity: T. s. griseus (triangles), T. s. doorsiensis (circles), and T. s. peninsulae (squares). The black symbols mark where collected specimens were taken from, while the open symbols refer to other records.
Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology , under the International Code of Zoological Nomenclature , the subspecies is the only taxonomic rank below that of species that can receive a name.
Eutamias is a genus of chipmunks within the tribe Marmotini of the squirrel family. It includes a single living species, the Siberian chipmunk (Eutamias sibiricus).The genus is often treated as a subgenus of Tamias, which is now restricted to the eastern chipmunk of North America. [1]
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 species name comes from the Latin cantitia, meaning "gray in color", and pes, meaning "foot", and the genus name comes from the Greek word Tamias, meaning "a distributor". [ 6 ] N. canipes was formerly considered a subspecies of N. cinereicollis , the gray-collared chipmunk, but it was brought to species status in 1960.
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.
