Arizona Cotton Rat (Sigmodon arizonae ssp. arizonae)

The Arizona Cotton Rat was described in 1890, the species contains five subspecies of which one, the nominate race, is considered extinct.

The nominate race was endemic to the Mogollon Plateau, a pine-covered section of the large Colorado Plateau in east-central Arizona, USA, where it was last seen in 1932. It disappeared not at least due to predation by feral cats.
