From transition forests at medium altitudes in eastern R. D. Congo. Kivu from Mount Ruwenzori to Itombwe (Schiøtz 1999). The type locality is at 1,750 m asl (Stuart et al. 2008).

Life History, Abundance, Activity, and Special Behaviors
Presumably has larval development in water (Stuart et al. 2008).

Trends and Threats
This species has a restricted range and its forest habitat is increasingly being lost to agriculture, logging, and encroachment by human settlements (Stuart et al. 2008). Although the population trend is unknown, it is thought to be decreasing. It has not been seen since the 1950s, when it was described by Laurent (1950) and a single subsequent specimen was collected in 1954 within Virunga National Park (Laurent 1972).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
