Discussion: Has been regarded as a monotypic genus by most recent workers but Boyeskorov (1999) treated the alces and americanus subspecies groups as species. They are said to be separated by the Yenisei River in Siberia. More information is required on the location and nature of the contact zone, particular in the upper Yenisei, Mongolia, and China. It has yet to be confirmed that both species occur or occurred in Mongolia and China. Genus revised by Peterson (1952); reviewed by Franzmann (1981, Mammalian Species, 154) and Geist (1998).
