Others members of the red deer group, which may represent separate species, are "C. corsicanus", "C. wallichi" and "C. xanthopygus". If so, "C. corsicanus" includes the subspecies "C. c. barbarus" (perhaps a synonym of "corsicanus"), and is restricted to Maghreb in North Africa, Corsica and Sardinia. "C. wallichi" would probably include the subspecies "C. w. kansuensis" and "C. w. macneilli" (both are perhaps synonyms of "C. w. wallichi"), and would be found from Tibet to central China. "C. xanthopygus" would probably include the subspecies "C. x. alashanicus" (perhaps a synonym of "C. x. xanthopygus"), and would be found from the Russian Far East to northeastern China. This would restrict the "true" red deer ("C. elaphus") to Europe, Anatolia, the Caucasus and northwestern Iran, and the elk/wapiti ("C. canadensis") to North America and the Asian regions of the Tian Shan, Altai, and Great Khingan. Alternatively, the "barbarus" group species are subspecies of the "true" red deer, while the "C. wallichii" and "C. xanthopygus" groups are subspecies of the elk/wapiti.
