From the IUCN Red List Species Account:


Range Description

This species occurs from southwestern Cameroon south to Monte Alen in mainland Equatorial Guinea (Rio Muni). It probably occurs up to over 1,000 m asl. Records from the island of Bioko (Equatorial Guinea) refer to Dimorphognathus africanus.

Habitat and Ecology

It lives in the vicinity of streams in forest, and only survives in secondary habitats at higher elevations. They lay eggs on leaves close to water, but not above water. The tadpole falls to the ground and develops on land (it never enters water). The tadpole does not have a fully developed alimentary canal, and so it does not eat, but instead is dependent on its yolk. The alimentary canal is only developed and functional at the time that the tadpole develops into a frog. This process is referred to as semi-direct development.


It is a common species.

Population Trend


Major Threats

It is presumably threatened by the loss of forest habitat for agriculture, logging and human settlements.

Conservation Actions

It occurs in Korup National Park (Cameroon) and Monte Alen National Park (Equatorial Guinea).

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its relatively wide distribution and presumed large population.

Taxonomic Notes

This form is probably a complex of at least three species (J.-L. Amiet pers. comm.).
