Tamias umbrinus (Uinta chipmunk)

Wikipedia Abstract

The Uinta chipmunk, or hidden forest chipmunk (Neotamias umbrinus), is a species of chipmunk, in the family Sciuridae. It is endemic to the United States.Formerly known as Tamias umbrinus, phylogenetic studies have shown it to be sufficiently distinct from the eastern chipmunk as to be placed in a separate genus, Neotamias. The same studies have also suggested that Palmer's chipmunk may actually be a subspecies of Uinta chipmunk, although the two are still generally regarded as separate species.
