Range Description This species is known only from Mount Nganha on the Adamawa Plateau, at 1,400-1,700m asl, in Cameroon, to which it is probably endemic.
Habitat and Ecology This species is found along watercourses in a few narrow gallery forests, and in seepage areas in nearby grassland. Tadpoles, almost certainly of this species, have been found in rock pools in streams.
Population It is known only from five specimens.
Population Trend decreasing
Major Threats This poorly known species is probably at severe risk from habitat loss due to smallholder farming activities and subsistence wood extraction.
Conservation Actions It is not known from any protected areas and protection of the remaining habitat in the range of the species is urgently needed. Further survey work is required to establish its distribution, current population status and threats.
Red List Status Critically Endangered (CR)
Rationale Listed as Critically Endangered because its Extent of Occurrence is probably less than 100 km2 and its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the extent of its habitat on Nganha Mountain is probably declining.
