Abrothrix manniis in the subgenus Abrothrix and was removed from the former concept of A. sanborni , mostly based on molecular grounds. Therefore, part of the data available in the literature for A. sanborni relates to A. mann. Monotypic.

Distribution. SC Chile, including N Chiloe I, and extreme WC Argentina .

Descriptive notes. Head-body 107 mm, tail 83 mm, ear 14 mm, hindfoot 25 mm; weight 28 g (other measurements beyond those of the holotype were not provided). See general characters of the genus under the Long-haired Soft-haired Mouse (A. longipilis ) account. Mann's Soft-haired Mouse is characterized by its nearly uniform dark color and moderately short tail (c.70% of head-body length). Dorsal pelage is soft, woolly, dense, and composed almost entirely of dark gray hairs, with cinnamon to buffy tips; cinnamon tint is more obvious at midline, giving a general dark brownish to blackish appearance. Mystacial vibrissae are abundant, dark, and moderately long, reaching bases of ears when pressed alongside head. Ears are short, rounded, and dark brown, with margins of inner surfaces covered with short fine blackish hair. Flanks are similar to dorsum butslightly grayer. Venter is ashy gray, with each individual hair being dark gray at base and paler at tip. Forefeet and hindfeet are dorsally covered by short ocherous hair. Ungual tufts are pale brown, shorter than claws on forefeet and larger than claws on hindfeet. Tail is uniformly blackish.

Habitat. Valdivian rainforests with dense canopy cover,tall trees, sparse shrubby cover, deep litter, abundant ground cover of bryophytes and bamboo, and gentle slopes at elevations less than 820 m.

Food and Feeding. Mann's Soft-haired Mouse eats high proportions of fungi and moderate amounts of mature arthropods and larvae, plant foliage, seeds, and fruits.

Breeding. Mann's Soft-haired Mouse breeds in spring and summer (September—April).

Activity patterns. Mann's Soft-haired Mouseis terrestrial and active day and night.

Movements, Home range and Social organization. No information.

Status and Conservation. Not assessed on The IUCN Red List as a separate species from Sanborn’s Soft-haired Mouse (A. sanborni ), which is classified as Least Concern. Descriptors of Mann's Soft-haired Mouse suggest that it might qualify for a threatened classification because of its limited extent of occurrence.
