This species has been recorded from several localities in the western Cameroon mountains from the Bamenda Highlands north-east to the Adamawa Plateau, with some outlying populations at lower altitudes to the south of this range on Mount Ngorro and the Yoko (Djan) Mountains. It has also been recorded from the Obudu Plateau in eastern Nigeria. It occurs in the submontane zone from 900-1,700m asl. The distribution is discontinuous, perhaps due to forest clearance in the 17th century.
Habitat and Ecology
It lives in or near flowing water in lower montane and submontane forest or herbaceous vegetation and gallery forests. At night it can be found in relatively dry areas along forest tracks and in agricultural areas. It can survive in deforested areas in temporary, eutrophic, silted streams that are low in oxygen. Breeding takes place in flowing water, with the males calling from rock cavities or from in the water.
It is reported to be common within its range.
Although this species is probably suffering from habitat loss, it appears able to adapt to some non-forest habitats.
It is not known to occur in any protected areas.
