This species is known only from two closely adjacent sites at 800-1,000 m asl in the northern Rift Valley of Ethiopia (Largen 2001). However, it has not been extensively surveyed beyond the type locality, so it is possible that it may be more widespread (A. Mengistu and S. Loader pers. comms. June 2012). Taking range as a proxy for extent of occurrence (EOO), this is estimated to be 133 km2.
Habitat and Ecology
This species is associated with permanent water (in which it breeds), which is provided at one site by pools deep amongst lava boulders, and by effluent streams from a hot spring at the other site, in a sub-desert steppe of volcanic rubble, xerophilous grasses and dense Acacia thickets (Largen 2001). It is unknown whether the species is tolerant to habitat alterations (A. Mengistu and S. Loader pers. comm. June 2012).
It appeared to be fairly numerous at its type locality in 1970 (Largen 2001) and in 2006 and 2008 (A. Mengistu and S. Loader pers. comms. June 2012).
The main threats to this species are probably related to environmental degradation resulting from expanding human settlements, with consequently increased populations of domestic livestock, a hazard which exists even within Awash National Park, where it occurs. However, the impacts of these activities on this species are not known (A. Mengistu and S. Loader pers. comms. June 2012).
Awash National Park is the only protected area from which it is currently known, but there is livestock encroachment within the park, so improved management is needed (A. Mengistu and S. Loader pers. comms. June 2012). More information is needed on this species' distribution, population status and natural history. Chytrid has been reported from closely related species from highland regions of Ethiopia, so chytrid screening is needed for this species (A. Mengistu and S. Loader pers. comms. June 2012). Taxonomic research is also needed to clarify the status of this frog.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since there is still very little information on its extent of occurrence, population status, ecological requirements and threats.
There is uncertainty regarding the taxonomic status of this species (A. Mengistu and S. Loader pers. comm. June 2012).
