The Chalchalero vizcacha rat (Salinoctomys loschalchalerosorum) is a species of caviomorph rodent in the family Octodontidae.[2] It is monotypic within the genus Salinoctomys. The species is endemic to a small area of northwestern Argentina, where it lives in shrublands bordering the salt flats of the Salinas Grandes.[1] Its diet consists of halophyte plants.[1]

It is a medium-sized rat species. Their fur is dark brown on top and white below. The tail is relatively long and ends in a black tassel. They reach a body length 14 to 16 centimeters and a tail length of 11 to 12 centimeters.[3]

The rodent is threatened by degradation of its unique habitat. It is named after an Argentine musical group, Los Chalchaleros, whose songs were popular with its discoverers.[4]
