Here we report the first record of Drymoreomys albimaculatus Percequillo, Weksler & Costa, (Cricetidae, Sigmodontinae) in Rio de Janeiro state, Brazil. The recently described taxon Drymoreomys albimaculatus is endemic to the Brazilian Atlantic Forest and its biology and genetics are still poorly known. Herein. PDF | Drymoreomys albimaculatus is a recently-described rodent and an Atlantic Forest endemic. It is rare and has a poorly defined geographic.
