This species is known only from Mount Manenguba and the Rumpi Hills in western Cameroon, though its range is not well understood. Its altitudinal range on Mount Manenguba is from 1,300-1,750m asl, and the single specimen from the Rumpi Hills was collected at 1,000m asl.
Habitat and Ecology
It lives on the verges of fast-flowing streams in submontane forest and degraded secondary habitats, where several individuals may cluster together on rocks in the splash zone. On Mount Manenguba it lives at a higher altitude than Werneria merteniana, but at lower elevations than W. bambutensis. It breeds in streams.
It is common within its limited range.
It is presumably at risk from forest loss due to agricultural encroachment and human settlement.
It may occur in the Rumpi Hills Forest Reserve, although this is not managed for biodiversity conservation; increased protection of the montane forest habitats in western Cameroon is rather urgently needed, particularly on Mount Manenguba.
