From the IUCN Red List Species Account:


Range Description

This species is known only from the foothills of the East Usambara Mountains in north-eastern Tanzania. All records have been from below 410m asl.

Habitat and Ecology

It is a terrestrial species of lowland forest, but also survives in mildly disturbed, selectively logged forest. Its breeding behaviour is unknown, but it might breed in puddles in tree roots (like Stephopaedes anotis).


It is not uncommon within its very small known range.

Population Trend


Major Threats

There is ongoing loss of its habitat due to agricultural encroachment, wood extraction, and human settlement.

Conservation Actions

It occurs in the Kwamgumi, Segoma and Mtai Forest Reserves, but these are not well protected and are in need of improved management.
