Resumen

The Andean swamp rat Neotomys ebriosus is a sigmodontine rodent restricted to the Central Andes of South America. A distribution map of the species in Peru have been previously drawn based on few of the localities where the species has been captured and collected. I update the distribution of the species in Peru based on new records from three different areas surveyed by the author, specimens at Museum collections in the United States and France from VertNet webpage, localities from the collection at the Natural History Museum of Universidad Nacional Mayor de San Marcos, and localities from the collection at the Natural History Museum of the Universidad Nacional San Agustín. The northern limit of the species distribution is increased based on new localities with collected individuals. Habitat used by N. ebriosus is mainly high Andean bogs; most individuals caught adjacent to the borders of Andean bogs and along streams near the bogs. Collected individuals leave unclear subspecies division and identity.
