This species is known only from extreme southern Nigeria and south-western Cameroon at low altitudes.
Habitat and Ecology
It lives in lowland moist forest and in degraded habitats near more mature forest and can be found in small groups along forest watercourses, often in undergrowth among dead leaves and in holes. It breeds in streams.
It is fairly common, though it is often absent from apparently suitable habitat.
This species is presumably affected by forest loss.
It occurs in Korup National Park.
