Notiomys edwardsii, also known as Edwards's long-clawed mouse, Edward's long-clawed akodont, or Milne-Edwards' long-clawed mouse, is a rodent in the tribe Abrotrichini from southern Argentina. It is the only species in the genus Notiomys, although species of Chelemys and Geoxus were formerly included in that genus.
A tuco-tuco is a neotropical rodent in the family Ctenomyidae. Tuco-tucos belong to the only living genus of the family Ctenomyidae, Ctenomys, but they include approximately 60 different species. The common name, "tuco-tuco", comes from the "tuc-tuc" sound they make while they dig their burrows.
The Brazilian tuco-tuco is a tuco-tuco species. It is found mainly in the state of Minas Gerais in southeastern Brazil, though Charles Darwin mentions it during his trip through present-day Uruguay.
The collared tuco-tuco is a tuco-tuco species from South America. It is found in southern Brazil, Uruguay and northern Argentina where it lives underground in a burrow it digs in savannah habitats. It is a relatively common species and the IUCN has assessed its conservation status as being of "least concern".
The southern tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Argentina.
The reddish tuco-tuco is a species of rodent in the family Ctenomyidae. Five subspecies have been recognized, some formerly designated as separate species. It is found in Argentina and Bolivia at altitudes from 600 to 4,500 m. This tuco-tuco is fossorial, like others in its genus. Its diet consists of underground tubers and roots. Its karyotype has 2n = 52 and FN = 78.
The tawny tuco-tuco is a species of burrowing rodent in the family Ctenomyidae. It is found in the desert regions of northern Chile and adjoining areas of Argentina.
The Maule tuco-tuco is a species of rodent in the family Ctenomyidae. It is found in Argentina and Chile, where it occupies several different types of habitats. It is a common species, and the IUCN has assessed its conservation status as being of "least concern". The common and scientific names refer to a river and region in Chile within its range.
The Mendoza tuco-tuco is a species of rodent in the family Ctenomyidae.
The highland tuco-tuco is a species of rodent in the family Ctenomyidae. It is found in high grassland in Argentina, Bolivia, Chile, and Peru where it lives in burrows.
Pearson's tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Uruguay, where it is found at elevations below 200 m. This tuco-tuco constructs burrows with multiple openings containing one to two nests of dried grass; it prefers areas of sandy soil but is somewhat adaptable. It is threatened by loss of habitat to development, agriculture and ranching. Multiple karyotypes have been reported, including 2n = 68–70, FN = 80–88, as well as 2n = 56, FN = 77–79, suggesting the taxon may represent several species. C. dorbignyi appears to be cytogenetically indistinguishable from the 2n = 70 form. The species is named after American zoologist Oliver Payne Pearson.
The Goya tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Argentina.
The social tuco-tuco is a species of rodent in the family Ctenomyidae. It is endemic to Argentina. Its natural habitat is subtropical or tropical dry lowland grassland.
The Talas tuco-tuco is a species of tuco-tuco endemic to eastern Argentina.
The robust tuco-tuco is a species of rodent in the family Ctenomyidae. It is a burrowing rodent and is endemic to the Tucumán Province of Argentina.
Budin's tuco-tuco was formerly considered a species of rodent in the family Ctenomyidae. It is endemic to southeast Jujuy Province in northwest Argentina. Given the extensive human presence in its limited range, it has been suspected to be threatened. The IUCN currently views it as a subspecies of C. frater. It was named after Emilio Budin, an Argentine specimen collector who worked with Oldfield Thomas.
D'Orbigny's tuco-tuco is a species of rodent in the family Ctenomyidae, named after French naturalist Alcide d'Orbigny. It is found in northeast Argentina. Its karyotype has 2n = 70, FN = 84–88, which is cytogenetically indistinguishable from some populations of C. pearsoni; the latter taxon may actually represent several species.
The forest tuco-tuco was formerly considered a species of rodent in the family Ctenomyidae. It is endemic to Salta and southeast Jujuy Provinces in northwest Argentina. The IUCN currently recognizes it as a subspecies of C. frater.
