Abstract

Caluromysiops irrupta is a rare marsupial that inhabits the western part of the Amazon forest. It is an arboreal and nocturnal species, and its real distribution is yet to be investigated. Since its description by Sanborn in 1951, only eight records were reported from Peru, Colombia, and northwestern Brazil. In this work, we provide a new record for Mato Grosso state, Brazil, based on a specimen captured during a faunal rescue of vegetation suppression. This record represents the easternmost limit of the distribution of the black-shouldered opossum and the second known specimen from Brazil, extending its range about 718 km toward an area close to lands under intensive use and high rate of deforestation. The present record is an evidence of the potential of faunal rescues for generating data, which are useful for conservation and management purposes in the Neotropics.
