Stampfli’s Greater Spot-nosed Guenon
Cercopithecus nictitans stampflii Jentinck, 1888
CR A2cd

The taxonomic position of this monkey is unresolved. It is believed to occur only in Liberia and western Côre d’Ivoire, but the greater spot-nosed guenons of Nigeria west of the Cross River (considered by some to represent C. n. insolitus), may also be included within this subspecies. Greater spot-nosed guenons throughout this region are in critical condition because of their very patchy distribution in an area of heavy hunting pressure. Cercopithecus nictitans stampflii should be a high research priority both for its taxonomy and population status. Its presence within any protected area is not confirmed.
