This species is known from the mountains of eastern Nigeria and western Cameroon at 1,200-2,000m asl. In Nigeria, it has been recorded from the Obudu Plateau, and in Cameroon it is known from Mount Manenguba, the southern fringe of the Bamileke Plateau (at Foto and Mount Bana), Mount Nlonako, and the Bamenda Highlands (in the Bafut-Ngemba Forest Reserve). At Mwakoumel on Mount Manenguba, it co-exists with Cardioglossa pulchra and C. venusta.
Habitat and Ecology
It lives in submontane and montane areas in forest and in dense secondary growth. Males call from shady situations along streams. It is a stream-breeding species.
It is common on Mount Manenguba at about 1,600-1,700m asl.
It is at risk because of forest loss as a result of expanding human settlements, agricultural encroachment, and removal of wood.
It does occur in the Bafut-Ngemba Forest Reserve, but additional habitat protection of the remaining highland forests in Cameroon, particularly Mount Manenguba, and in Nigeria, is needed.
