We present country records and a list of voucher specimens for Mussurana bicolor (Peracca, 1904) (Serpentes, Colubridae) from Bolivia. There is scarce information on museum specimens and locality data from Bolivia for this species in the scientific literature. Additionally, we discuss two newly collected specimens from the Llanos de Moxos, a floodplain in the Beni Department. This account contributes to the knowledge of the northwestern distributional status of M. bicolor and summarizes available data for Bolivia.
