This species is endemic to Ngezi Forest, on Pemba Island, in Tanzania. It occurs close to sea-level.
Habitat and Ecology
It appears to be dependent on lowland forest. At its only known site it was found calling in forest trees overhanging a small pool, but it was absent from the grasses and herbage at the other end of the same pool in a more open situation. It presumably breeds in water by larval development.
It appears to be a rare species. Only 10-20 males were heard calling at its only known site.
It is restricted to a tiny area where its forest habitat is at risk from harvesting of wood, and small-scale agriculture.
It occurs in the Ngezi Forest Reserve which requires careful management for this extremely rare species.
