This species is classified as Endangered as analysis has shown that it has a very small range which is declining in quality and size, and a very small population which is suspected to be decreasing owing to habitat loss and hunting pressure. Urgent conservation action is required to preserve tracts of forest in Angola large enough to support a viable population.
