This species was previously thought to be endemic to the Oshie-Obudu Ridge in Cameroon and Nigeria, as it was found in Acha Tugi on Mount Oshie in Cameroon and from the Obudu Plateau in Nigeria. However, it has now also been recorded from the Gotel Mountains in Cameroon (Gvoždík 2011). Its altitudinal range is 1,640–2,010 m Asl and its EOO is 9,951 km2.
Habitat and Ecology
This species lives in and around relict patches of montane forest, which are now fragmented, and also in secondary vegetation in which no trees remain. It has been found on steep slopes of scree, boulders and clay, overgrown with a dense cover of high grass and trees. It has also been found around streams, where it presumably breeds by larval development similar to other species in the genus.
This species is generally poorly known. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
It is threatened by habitat loss due to expanding agricultural activities, human settlements, overgrazing and logging.
This species occurs in the Cross River National Park in Nigeria.
Further measures are urgently needed to protect the remaining patches of habitat in its very small range.
Additional survey work would be useful to determine the current population status of this species.
Red List Status
Listed as Vulnerable because its extent of occurrence (EOO) is 9,837 km2, it occurs in fewer than 10 threat-defined locations, and there is decline in the extent and quality of its forest habitat in the Cameroonian and Nigerian mountains.
