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]
[11] First described by Mark Catesby in his 1743 The Natural History of Carolina, Florida, and the Bahama Islands, the chipmunk was eventually classified as Sciurus striatus by Linnaeus, meaning "striped squirrel" in Latin. [12] [13] The scientific name was changed to Tamias striatus, meaning "striped steward", by Johann Illiger in 1811. [14]
Tamias striatus doorsiensis is a subspecies of the eastern chipmunk that is only found in Door, Kewaunee, northeastern Brown, and possibly Manitowoc counties in northeastern Wisconsin. [1] It was described by C. A. Long in 1971.
Mearns's squirrel is a distinctive subspecies of the Douglas squirrel that instead inhabits xeric pine forests in a small portion of Baja California. [ 6 ] Throughout most their range, Douglas squirrels essentially replace the niche of the American red squirrel , which inhabits the coniferous forests of the rest of North America.
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. [8]
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 scientific name of a species is a binomial or binomen, and comprises two Latin words, the first denoting the genus and the second denoting the species. [5] The scientific name of a subspecies is formed slightly differently in the different nomenclature codes. In zoology, under the International Code of Zoological Nomenclature (ICZN), the ...
