We documented new records of Choloepus didactylus extending up to 820 km south of its current geographic distribution. These records, and others found in literature for the central‐southern Amazon, evidence a southern expansion of about 30% of the known species' area of occurrence and help shedding light on decades of uncertainties about its real distribution. in Portuguese is available with online material. Resumo Neste estudo, documentamos novos registros da “Preguiça de Dois Dedos”, Choloepus didactylus (Linnaeus, 1758) estendendo‐se até 820 km ao sul de sua distribuição geográfica atual. Esses registros, e outros encontrados na literatura para o centro‐sul da Amazônia, evidenciam uma expansão para o sul de cerca de 30% da área de ocorrência da espécie conhecida e ajudam a esclarecer décadas de incertezas sobre sua real distribuição.
