Range DescriptionThis species occurs in the montane regions of eastern Democratic Republic of Congo, Uganda, Rwanda and Burundi. Its range, taken as a proxy for extent of occurrence (EOO) is estimated to be 12,498 km2. Its altitudinal range is still unclear, though it seems to be montane. Individuals from the Bwindi Impenetrable Forest (Uganda) have been found at 2,070 m asl (Drewes and Vindum 1994); in the Democratic Republic of Congo it has been found as high as 2,815 m asl on the Itombwe Plateau (E. Greenbaum pers. comm. February 2011), and above 1,800 m in Kahuzi-Biega National Park (M. Menegon pers comm June 2012). In Rwanda it has been found as low as 1,780 m asl in Nyungwe National Park (J.M. Dehling pers. comm. May 2011; M. Menegon pers comm June 2012). Recent surveys in Burundi indicate that this species occurs between 1,800 and 2,200 m asl in Bururi Forest Reserve (D. Blackburn and E. Greenbaum pers comm. July 2013).
