|Taxonomic Notes:||Molecular data confirm that the subpopulation in Saja (Kaffa) forest pertains to this nominal form (A. Mengistu and S. Loader pers. comm. June 2012).|

Listed as Endangered because its extent of occurrence (EOO) is estimated at 829 km2, its population is considered to be severely fragmented, and there is continuing decline in the extent and quality of its habitat in the Gughe Mountains and Saja forest in southwest Ethiopia.
|Previously published Red List assessments:|
|Range Description:||This species occurs in the Gughe Mountains, at 2,600-3,000 m asl and Saja forest at 1,960 m asl in the southwest of Ethiopia (Largen 2001; A. Mengistu and S. Loader pers. comm. June 2012). It was previously reported from the Bale Mountains (Weinsheimer et al. 2010), but this record appears to be a misidentification (A. Mengistu and S. Loader pers. comm. June 2012). It is possible that it may occur more widely, in the intervening forest patches between Saja forest and Gughe Mountains (A. Mengistu and S. Loader pers. comm. June 2012). Its range, taken as a proxy for its extent of occurrence (EOO), is estimated to be 829 km2, which is also considered a very generous estimate of its area of occupancy (AOO), given that this species needs forest to survive.|

|Population:||It was reasonably numerous in at least two localities in 1975 (Largen 2001); field work in 2008 in Gughe recorded two specimens and a single specimen in 2009 in Saja forest, suggesting that this is not a common species based on these limited surveys (A. Mengistu and S. Loader pers. comm. June 2012). Its population is considered to be severely fragmented.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is confined to montane forest remnants, and has not been found in degraded habitats (Largen 2001; A. Mengistu and S. Loader pers. comm. June 2012). Calling males have been found along the banks of streams, in which larval development presumably occurs. The eggs are presumably laid in nests on land, near the water.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||There are no reports of this species being utilized.|
|Major Threat(s):||The main threats are forest clearance, human settlement, and small and large-scale agricultural encroachment. Both the Gughe Mountains and Saja forest are heavily populated and intensively cultivated, and only small patches of montane forest remain (Largen 2001; A. Mengistu and S. Loader pers. comm. June 2012).|
|Conservation Actions:||It is not currently known to be present in any protected areas, and the protection of forest remnants in the Gughe Mountains and Saja forest are urgently needed. Given the prevalence of chytrid across the Ethiopian highland habitat (including southwest forests) it is important to determine whether it is present in Gughe Mountains (Gower et al. 2012). More information is needed on this species' distribution, especially in intervening areas between known sites, population status and natural history.|
