According to the Wallacean shortfall, knowledge about the geographic distribution of most species is still incomplete. Cryptonanus agricolai (Moojen, 1943) is a didelphid marsupial considered Data Deficient by IUCN, since species records are few and sparse. Although little information is available for the species, it is generally associated with xeric habitats from Caatinga and open formations of the Cerrado in east-central Brazil. Here we report the occurrence of C. agricolai in the Atlantic Forest core, a new ecoregion for the species, based on a recent collected voucher - identified through morphological and molecular analysis-from a Mussununga formation in Reserva Biológica do Córrego do Veado, southeastern Brazil. This record extends the occurrence of the species to more than 1 700 000 km2 and lower its altitudinal range limit to 108 m.
