This species is known from two forest reserves in the West Usambara Mountains, northeastern Tanzania, and is known to occur between 1,300–1,900 m asl (Blackburn 2009). Although it is possible that it may occur more widely, it appears to be restricted to the West Usambara Mountains. These mountains have an estimated extent of less than 320 km² (Burgess et al. 2007 in Blackburn 2009).
Habitat and Ecology
This species has been found in leaf litter in dense, montane forest (Blackburn 2009). It is presumed to breed by direct development.
No population status information is currently available for this species.
The major threat to this frog is continuous loss and degradation of its habitat due primarily to agriculture, grazing, logging and anthropogenic modification of the habitat, which has been taking place over the last 2,000 years. However, it appears that habitat degradation may have escalated in the last 110 years with the arrival of European colonizers (Conte 2004). Agricultural/pastoral and forestry uses of the landscape occur throughout these mountains and at most elevations (D. Blackburn pers. comm. March 2010).
Although this species occurs in two neighbouring forest reserves, it is still threatened by habitat degradation and loss. What is more, it is a cryptic species; thus, further survey work is needed to determine its distribution, population status and natural history.
Red List Status
Listed as Endangered because its extent of occurrence is less than 5,000 km², all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in West Usambara Mountains.
