Bothriechis guifarroi is a species of venomous green palm pitviper discovered in 2010 in the Texiguat Wildlife Refuge, in Northern Honduras. Bothriechis guifarroi joins two other species of the genus Bothriechis, B. marchi and B. thalassinus, found in Chortís Highlands of Honduras. Its color pattern and scalation is similar to other Honduran palm pitvipers, but genetic analysis reveals it to be more closely related to the B. lateralis and B. nigroviridis species more than 600 km to the southeast, in the mountains of Costa Rica and Panama.
