This species occurs in extreme southeastern Nigeria (from where it has recently been recorded in the Oban Hills (M. Gartshore pers. comm.), southern and southwestern Cameroon and mainland Equatorial Guinea, generally at low elevations up to 900 m asl.
Habitat and Ecology
This is a lowland forest species occurring in hilly areas up to 900 m asl. It favours forests that have humid, but not marshy, floors, and requires tall forest with a closed canopy. It breeds in fast, rocky streams with clean water. The males call from the ground not far from water.
It is a common species, especially at 300-900 m asl.
Due to its large range it is likely that there are declines in some areas due to habitat loss.
It occurs in Cross River National Park (Nigeria), Korup National Park (Cameroon), Monte Alen National Park (Equatorial Guinea), and probably in some other protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its tolerance of habitat modification and its presumed large population.
