The golden vizcacha rat (Pipanacoctomys aureus) is the single species of the genus Pipanacoctomys of the rodent family Octodontidae. This animal is tetraploid and has 4x = 2n = 92 chromosomes. This species and its sister-species, the plains viscacha rat (Tympanoctomys barrerae) (4x = 102), appear to have arisen from the diploid mountain vizcacha rat (Octomys mimax), (2x = 2n = 56) as a result of the doubling and subsequent loss of some chromosomes.
