Known only from five locations, one at Muanenguba and four in the Bamenda Highlands, and has an extent of occurrence of < 5,000 km and an area of occupancy of < 500 km². There is continuing decline because of ongoing clearance of remaining montane forest at Muanenguba and in the Bamenda Highlands outside of protected areas. Future encroachment into protected areas also poses a serious threat.
