This species is known from southern and southwestern Cameroon, Equatorial Guinea (Bioko Island and Rio Muni), much of Gabon, central Congo, southwestern Central African Republic, and northeastern Democratic Republic of Congo. It has been found up to 1,050 m asl, but it is generally a lowland species.
Habitat and Ecology
It lives in moist lowland tropical rainforest, including primary and secondary forest with dense undergrowth in slightly marshy situations. It avoids well-drained forest. It breeds in small streams and the males call from cavities near water.
It is a very common species in Cameroon, but apparently less common in some other parts of its range.
Although it can tolerate a certain level of habitat alteration, it cannot survive outside forest is almost certainly affected by ongoing forest loss.
It occurs in several protected areas.
