This species is known from eastern Nigeria on the Obudu Plateau and the higher parts of the Oban Hills, and from a number of montane localities in western Cameroon, including Mount Cameroon, the Rumpi Hills, Mount Kupe, Mount Manenguba, the Mbos Cliffs, and Foto. It is also known from Mount Kala and Mount Mbam-Minkoum near Yaoundé in southern Cameroon. Its altitudinal range is 800-2,000m asl.
Habitat and Ecology
It is confined to montane forest near streams and small waterfalls, and requires forest with a closed canopy. It moves further from watercourses during the rainy season. It presumably normally breeds in streams, though tadpoles have been found in a water tank.
It is generally uncommon.
The main threat is habitat loss, primarily due to smallholder farming activities, which is continuing over much of its range.
It occurs in the Cross River National Park in Nigeria, but there is a need for improved protection of other sites at which the species is known to occur.
