This poorly known species has been recorded only from southern Senegal (Casamance), Guinea, Sierra Leone, and southern Côte d’Ivoire (at Lamto). It presumably occurs in Guinea-Bissau and Liberia, though there are no confirmed records from these countries.
Habitat and Ecology
It lives in humid savannah, secondary forest, and gallery forest. Animals have also been found in a ditch near degraded former forest (farm bush), indicating that this species is reasonably adaptable to secondary habitats. It breeds in temporary marshes and permanent pools.
There is very little information on its population status. It was described from museum specimens collected many years previously, and since it was described it has not yet been related to any species in the wild, though it appears to be taxonomically valid (Rödel pers. comm.).
There is very little information on threats to this species.
It has not been recorded from any protected areas, though it is likely to occur in some. Further research is needed on the population status and distribution, use and trade, and threats to this species.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements.
This species was previously confused with Ptychadena bibroni (Perret 1997, 1999).
