Owl-faced guenon  (Cercopithecus hamlyni)

The owl-faced guenon is a graceful monkey from Africa, with a long tail and a silky, olive coat (2) (4). The name ‘guenon' is given to a group of monkeys, all with distinctive ‘moustaches', light nose spots and striped sideburns (4). The owl-faced guenon has a black face with a yellowish patch above the brow, and a thin, white stripe running down the nose (2). The scrotum and perineum are bright blue (2). Two subspecies have been described: Cercopithecus hamlyni hamlyni and Cercopithecus hamlyni kahuziensis (5).
