This species is known only from its type locality, Lambarene, Ogowe, in west-central Gabon, and (on the assumption that Phrynobatrachus brongersmai is a synonym of this species), from Grand Cape Mount in western Liberia.
Habitat and Ecology
This species' habitat and ecological requirements are presumably similar to those of most other members of the genus, and it likewise presumably breeds in water.
There are no recent records from either country, presumably due to lack of herpetological work within its range, although recent collections of frogs from southern Guinea might refer to P. brongersmai (Rödel pers. comm.).
There is no information on threats to this species.
The taxonomic status of both this species and P. brongersmai needs to be re-examined.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.
Phrynobatrachus brongersmai (Parker, 1936) from Liberia has long been considered a synonym of P. ogoensis, following Loveridge (1941). However, this synonymy is highly improbable on biogeographic grounds.
