Tim Davenport of the Wild Conservation Society and colleagues in Tanzania, Africa, just discovered a new genus of monkey - the first in 83 years!
Known locally as Kipunji, it stands at about 90cm (3ft) tall, is grey-brown in colour with off-white fur on its stomach and on the tip of its long curly tail, and has a crest of long hair on the top of its head. Adults have a distinctive call, described as a "honk-bark".
