This species is known only from the type locality at the foothills of the Bale Mountains, in Bale Mountains National Park, Ethiopia (A. Mengistu and S. Loader pers. comms. June 2012) at 1,550 m asl. It is possible that it may occur slightly more widely (A. Mengistu and S. Loader pers. comms. June 2012).
Habitat and Ecology
It has been found in Podocarpus forest amongst herbaceous vegetation on the forest floor, and in a shallow, stagnant pool, devoid of aquatic vegetation, close to the edge of a fast-flowing river (Largen 2001). As with other congeners, it is expected to reproduce by larval development. There is no information on whether it can tolerate habitat disturbance.
While there has been recent survey work in this species' range (Gower et al. 2013), this frog was not a part of that study. The population status of this species is unknown, and there is no information on whether it is severely fragmented. It was last collected in 2006 at its type locality (A. Mengistu and S. Loader pers. comms. June 2012).
As it occurs in a protected area, there is some level of protection afforded to this species (A. Mengistu and S. Loader pers. comms. June 2012). If it were to occur outside of this area it might be threatened by environmental degradation resulting from increasing human settlement, with the consequent exploitation of resources (particularly forest resources) for both subsistence and commercial purposes; however, this still requires confirmation.
It is only known from Bale Mountains National Park (Gower et al. 2012), although this protected area is not formally gazetted. There is a long-running conservation programme in the Bale Mountains National Park (Ethiopian Wildlife Conservation Authority and Frankfurt Zoological Society; Frankfurt Zoological Society 2007), but there is a lack of amphibian-specific activities and there is increasing encroachment within the Park, so improved park management is needed (Frankfurt Zoological Society 2007, Gower et al. 2012). More information is needed on this species' distribution, population status, natural history and threats.
Red List Status
Data Deficient (DD)
