This species is known only from the Mount Nimba area in extreme south-eastern Guinea and north-eastern Liberia, from the Taï National Park in south-western Côte d’Ivoire, and from Draw River and Boi Tano Forest Reserves, Ghana. It presumably occurs a little more widely than this, although it has not been found in surveys of many intervening areas.
Habitat and Ecology
All specimens have been found in primary forest close to inselbergs in leaf-litter. Its biology and breeding are unknown, although most records have come from drier parts of the forest suggesting that it is not dependent on water for breeding.
It is an extremely rare species.
It is affected by the loss of forest habitat for agriculture, logging and human settlements. On Mount Nimba it is also threatened by potential mining concessions.
It occurs in Taï National Park and the Mount Nimba World Heritage Site.
Red List Status
Listed as Endangered because it is dependent upon primary forest near inselbergs, and so its Area of Occupancy is probably less than 500km2, its distribution is severely fragmented, and the extent of its habitat is declining.
