This species is known to occur between 1,470 and 2,004 m asl within two protected areas in southern Viet Nam: Bidoup-Nui Ba National Park, Lac Duong District, Lam Dong Province (Rowley et al. 2010) and Ta Dung Nature reserve, Dak Glong District, Dak Nong Province (Rowley et al. 2012). Further surveys are likely to expand the known range to adjacent parts of the Langbian Plateau including Chu Yang Sin National Park to the northwest, and Phuoc Binh National Park to the southeast (Rowley et al. 2010). The species is likely to have occurred more widely in the past, prior to habitat loss and fragmentation in the area. The area of its range, which is taken as a proxy for extent of occurrence, is estimated to be 2,082 km2. The species occurs in two geographically distinct, threat-defined locations, separated by an area of unsuitable habitat at lower elevations.
