Urocitellus is a
paraphyletic to the prairie dogs and marmots,[1] and could therefore no longer be retained as a single genus. As a result, Urocitellus is now considered as a genus in its own right.[2]
All but two species are native to the northern and western parts of North America, from California and Minnesota through the north-western United States and western Canada; the Arctic ground squirrel inhabits Arctic terrain on both sides of the Bering Strait, while the long-tailed ground squirrel is exclusively found in Asia. The name of the genus is said to be derived from the Latin uro, meaning "tail" and citellus for "ground squirrel".[2] The proper word for "tail" in classical Latin is cauda.[3] Oura (οὐρά) is the ancient Greek word for "tail".[4]
