Barbary ape (7)
I believe the answer is:
macaque
'barbary ape' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for macaque that I've seen before include "Barbary ape" , "Monkey of the Eastern hemisphere" , "Monkey with a short or no tail" , "Monkey with a long face" , "Long-tailed monkey" .)
