Tamias Illiger, 1811 . Prodr. Syst. Mamm. Avium., p. 83.

TYPE SPECIES: Sciurus striatus Linnaeus, 1758 .

SYNONYMS: Eutamias Trouessart, 1880; Neotamias A. Howell, 1929 .

COMMENTS: Tribe Marmotini (Moore, 1959) . Nearctic forms revised by Howell (1929). Sutton (1992) provided a key to the species. Includes Eutamias ( sibiricus), Tamias ( striatus), and Neotamias as subgenera (Corbet, 1978c:85; Ellerman, 1940:428; Levenson et al., 1985; Nadler et al., 1977). Disagreement exists regarding the status of Eutamias and Neotamias; see White (1953), Ellis and Maxson (1979), Hall (1981:337), and Patterson and Heaney (1987). Levenson et al. (1985) found that T. (T.) striatus and T. (E.) sibiricus together formed the primitive sister group to Neotamias species; if this is confirmed, it renders Eutamias in the generic sense paraphyletic.
