Bouvier's red colobus

Bouvier's red colobus, Piliocolobus bouvieri, is a colobus monkey of swampy forests around the Congo River, between the mouths of the Alima and Oubangui Rivers in the Republic of the Congo. It was rediscovered in February 2015 by Lieven Devreese and Gael Elie Gnondo Gobolo, who spotted it on the Bokiba River in Ntokou-Pikounda National Park, after four decades without a confirmed sighting. Its body fur is brownish red and lighter than that of its closest relative, Pennant's colobus, with a smaller black to chocolate brown patch on the head, a white chin and whiskers, a black band from above the eyes to the temples and large pink eyerings. The tail is long for its small body. Described in 1887, it was long treated as a subspecies of Pennant's colobus and was raised to species rank by Colin Groves in 2007. It shows no fear of humans, which makes it easy prey for bushmeat hunters, and in 2019 the IUCN changed its status from critically endangered to endangered.
