The Sun-tailed Monkey (Cercopithecus solatus), also known as the Sun-tailed Guenon, is a primate that lives semi-terrestrially in one hilly area of moist evergreen forest in Gabon.
The Sun-tailed Monkey was only discovered in 1988, so not much is known about it. It is a frugivore. It weighs up about 4 - 9 kg. Troops consist of one adult male and several females and young.
