Mustela or Vison? Evidence for the taxonomic status of the American mink and a distinct biogeographic radiation of American weasels
Journal/Book Name, Vol. No.:
Molecular Phylogenetics and Evolution, vol. 52, no. 3
Harding and Smith (2009:639) note that the American Mink (treated as Neovison vison in Wilson and Reeder eds. 2005), together with America weasels M. frenata, felipei, and africana, represents a New World radiation distinct from Eurasian Mustela. They propose these species be recognized as a genus separate from Mustela, arguing that, despite an earlier claim that it could not be used for a North American group, the senior available & applicable genus name for the group should be Vison Gray, 1843. Since Harding & Smith also argued that additional studies should be undertaken before taking this action, ITIS is currently recognizing both the New World and Old World radiations of Mustela in genus Mustela pending further research

ITIS taxonomy is based on the latest scientific consensus available,
and is provided as a general reference source for interested parties.
However, it is not a legal authority for statutory or regulatory purposes.
While every effort has been made to provide the most reliable and up-to-date
information available, ultimate legal requirements with respect to species
are contained in provisions of treaties to which the United States is a

been published in the Federal Register. For further information on U.S.
