Justification:
This poorly known species is listed as Near Threatened as it is likely to be declining moderately rapidly owing to habitat loss, as well as exploitation by hunters and trappers. Its population size could be small, as it is largely restricted to primary forest, and it should be carefully monitored.

History:

2008	–	Near Threatened
2004	–	Near Threatened
1996	–	Endangered
1994	–	Endangered
