This species is known only from two general areas in south-western Cameroon: Apouh and Koupongo, near Edéa, in southern Cameroon (these two localities are 50km apart, and are separated by the Sanaga River). Records from the northern part of Korup National Park, east to Nguti, and north to Mount Nta Ali (Lawson 1993) are based on misidentifications and refer to Astylosternus diadematus (J.L. Amiet pers. comm.).
Habitat and Ecology
It lives in and near flowing water in lowland forest, and can survive in tall, secondary forest. It breeds in small streams and in marshy depressions with very small, superficial streams.
It appears to be a rare species occurring at low densities in the southern parts of its range.
The major threat to the species is habitat loss and degradation.
It might occur in the Douala-Edea Forest Reserve and Lac Ossa Wildlife Reserve. The remaining forest habitat in south-western Cameroon is urgently in need of improved protection.
