This species is only known from the Idanre Hills, in Ondo Province, southwestern Nigeria. It was previously thought that it may occur in similar habitats in southwestern Nigeria, but subsequent surveys in similar habitat around the type locality have failed to record it which suggests it could be micro-endemic (Onadeko et al. 2014). It occurs in a single threat-defined location and its EOO is 23 km2.
Habitat and Ecology
This species is closely associated with gneiss domes or inselbergs in the forest zone, though is absent from similar inselbergs in the savanna belt. It lives terrestrially in patches of shrubby vegetation and forest on the gneiss domes. The eggs are probably laid on soil, and the tadpoles then disperse by crawling out on the wet, sloping (often almost vertical) rock.
It is reported to be very common within its small known range, and tadpoles are abundant during the wet season. Surveys in 2013 recorded this species at its type locality for the first time since 1970; although this is not due to rarity, but rather that it had not been searched for since its' last observation (Onadeko et al. 2014). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
There is ongoing logging on the Idanre Hills inselbergs and other human activities such as small-scale farming. The frog does not seem to use forest during the breeding season, so the non-breeding habitat of the species is most likely affected by ongoing logging activities. Agricultural runoff from the farming in the hills is also another threat.
This species is not known from any protected areas.
There is a need for protection status for Idanre Hills (Onadeko et al. 2014).
There is a need for population monitoring given that it is known from only a single location.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its extent of occurrence (EOO) is 23 km2, it occurs in one threat-defined location, and there is ongoing decline in the extent and quality of its habitat.
This species was under the generic name Amietophrynus but is now treated under Sclerophrys (Frost 2016).
