This species ranges from the Adamawa Plateau in central Cameroon south to southwestern Congo and as far inland as Nouabalé-Ndoki National Park, Congo (Jackson and Blackburn 2007). There are no records from Equatorial Guinea, Gabon and the Central African Republic though these areas are somewhat included in the species' distribution on the map, but it is presumed this species occurs in these countries. It is a lowland species that avoids the littoral zone, and probably occurs up to at least 1,200 m asl.
Habitat and Ecology
It lives in and around raphia swamps, ditches, marshes and small pools in forest (including seasonally flooded forest), degraded secondary habitats (farm bush), and gallery forests in the savannah zone. It breeds in still water.
It is a very common species.
It is an adaptable species and it is presumably not seriously affected by forest loss.
It presumably occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and its presumed large population.
J.-L. Amiet (pers. comm.) considers that this species, together with Phrynobatrachus manengoubensis, might be synonyms of Phrynobatrachus werneri (or they might collectively constitute parts of a complex of more than one species).
