The long-clawed mole mouse is a small rodent with tiny eyes and ears and long foreclaws. The forest-dwelling nominate form in southern Chile is nocturnal and uses both underground spaces and leaf litter.
The regional account reports a mass of about 25 g and head-and-body length near 100 mm. It describes very small eyes and ears, long foreclaws, and short, dense fur.
The nominate form in the Aysén account is mainly nocturnal and partly subterranean. It also occurs in leaf litter, herbaceous cover, and runways beside logs, and eats small invertebrates, vegetation, and fungi.
