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.〔Gallardo, M. H. ''et al.'' (2004). (Whole-genome duplications in South American desert rodents (Octodontidae) ). ''Biological Journal of the Linnean Society, 82'', 443-451.〕 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. ==Description== The golden vizcacha rat grows to a head-and-body length of about with a tufted tail of about . The dorsal fur is golden-blond and the underparts are white.
