It is found only in northwestern Argentina.[2] DescriptionThe dorsal surface of Abrothrix illuteus is a uniform olive-gray in colour with tufts of white hairs on the chin and white bases to the hairs in the inguinal area. The ventral surface is ashy-gray. The hair is soft and long and the short tail is well-covered with hair. The feet are large, have claws of the same size on fore and hind feet, and have naked soles. The skull is robust with a long muzzle.[3] Distribution and habitatAbrothrix illuteus is found at moderate elevations in Catamarca Province and Tucumán Province, in northwestern Argentina, on the eastern flanks of the Andes at elevations between about {{convert|700|and|2500|m|ft|-2|abbr=on}}. Its presence at higher altitudes in the Nevados del Aconquija mountains on the border between the two provinces requires confirmation. Its typical habitat is moist forests of Podocarpus parlatorei and Alnus acuminata on steep hillsides. At higher elevations it inhabits areas with rough grasses and bushes alongside streams.[3]EcologyIn a research study into the diet of the barn owl (Tyto alba) in Tucumán Province, this mouse was the second most frequently found item.[3] StatusAlthough the population size and abundance of this mouse is unclear, it has a large range and is present in some protected areas, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". The chief threats it faces are likely to be from logging, wildfires and cattle grazing.[1] References1. ^1 2 {{IUCN|id=735|title=Abrothrix illutea |assessor=IUCN |assessor-link=IUCN |version=2018.1 |year=2016 |accessdate=2 October 2018}} 2. ^1 Musser and Carleton, 2005, p. 1089 3. ^1 2 3 {{cite book|author1=Patton, James L.|author2=Pardiñas, Ulyses F.J.|author3=Guillermo D’Elía|title=Mammals of South America, Volume 2: Rodents|url=https://books.google.com/books?id=4aHLBgAAQBAJ&pg=PA114 |year=2015 |publisher=University of Chicago Press |isbn=978-0-226-16957-6 |pages=109–115}} Literature cited
