Bothriopsis bilineata bilineata (Wied, 1821) (Serpentes: Viperidae): new records in the states of Amazonas, Mato Grosso and Rondônia, northern Brazil

Although widely distributed in the Brazilian Amazonia, there are few published records of Bothriopsis bilineata in this region, with large gaps between them. This scarcity of reports of B. bilineata in nature may be caused by its arboreal habits, cryptic color, and a possible low density in many areas. Here we provide new registers of the subspecies B. b. bilineata, improving the knowledge of its distribution
