Geoxus valdivianus, also known as the long-clawed mole mouse[1] or Valdivian long-clawed akodont,[2] is a species of rodent in the tribe Abrotrichini of family Cricetidae found in the Valdivian temperate rain forests and Magellanic subpolar forests of Argentina and Chile.

[3] The long-clawed mole mouse is a small shrew-like mammal with a short tail and a total length of about 14 cm (5.5 in).

[1] Its habitat is the forests of Nothofagus, Saxegothaea and bamboo found in this region, as well as tussock grassland, marshes and wet meadows; its altitudinal range is from sea level to the tree line.

[4] The long-clawed mole mouse digs a burrow and also moves about in surface runways near fallen logs and in dense undergrowth.

It is mainly nocturnal, leaving its burrow briefly to feed on earthworms and other small invertebrates, supplemented by plant material.
