The Chalchaleros-viscacha rat ( Tympanoctomys loschalchalerosorum , Syn. : Salinoctomys loschalchalerosorum ) is a living in South America rodent species from the family of octodontidae (Octodontidae). It was not scientifically described until 2000 .
It is a medium-sized species of Trug rats. Their fur is black-brown on the top and white on the belly. The tail is relatively long and has a black tassel. They reach a head body length of 14 to 16 centimeters and a tail length of 11 to 12 centimeters.
Chalchaleros viscacha rats are known so far only from the salt desert Salinas Grandes in the Argentine province of La Rioja . There they have evidently adapted to a very dry habitat with salt plants . Otherwise nothing is known about their way of life. In the same year, the same research team found another previously unknown species of tussock with the golden viscacha rat.
The name, which also occurs in the specific epithet loschalchalerosorum , honors the Argentine music group Los Chalchaleros , whose music the research group had heard during their activity.
The IUCN lists the species as critically endangered due to its very limited range .
