Taxonomy. Phyllotis alisosiensis Ferro, Martinez & Barquez, 2010, “El Papal, 2175 m (27°11’S 65°57°W), Parque Nacional Campo de Los Alisos, Departamento Chicligasta, Tucuman, Argentina.”

Overall morphology and cytochrome-b sequences suggest that P. alisosiensis could be subsumed under P. anitae, pending additonal research. Monotypic.

Distribution. Known only from two localities in Sierra del Aconquija, Tucuman Province, NW Argentina .

Descriptive notes. Head-body 124-144 mm,tail 121-139 mm, ear 20-24 mm, hindfoot 29-32 mm; weight 35-70 g. The Los Alisos Leaf-eared Mouse is medium-sized, with long and fluffy fur, cinnamon brown dorsum flecked with black hairs, and strongly cinnamon venter. Guard hairs are entirely black and project 4-5 mm beyond underfur. Transition between dorsal and ventral colors is gradual. Ears are dark, scarcely haired except for conspicuous patches on anterior edges; inner surfaces are covered with dark brown hair. Inconspicuous grayish post-auricular patch is present. Tail is strongly bicolored, dark gray above and whitish below, about same length as head-body length. Manus and pes are covered dorsally with short but dense white hair; ungual tuft covers each claw. Ventral mystacial vibrissae are short and white.

Habitat. Southernmost end of Yungas at elevations of 1234-2175 m. Los Alisos Leafeared Mice were trapped in deciduous forest of Andean alder (Almus acuminata, Betulaceae) and cloud forest.
