Geographic boundaries and natural history notes of the microendemic endangered frog Eupsophus migueli Formas, 1977 (Alsodidae) in the Mahuidanche Range, southern Chile

: Eupsophus migueli is considered a microendemic endangered species inhabiting the temperate Nothofagus forests of the Mahuidanche Range of southern Chile. However, this categorization is based on scarce data about its distribution and natural history. In order to assess these parameters, this article reports new geographic records obtained through intensive fieldwork between 2011 and 2016. Considering this, an updated distribution map for E. migueli is proposed, and new data about natural history traits and habitat use are provided. The information obtained in this study is discussed considering the zoogeographical importance of E. migueli, and confirms the species IUCN conservation status.
