We studied genetic characteristics within and among gelada (Theropithecus gelada) populations inhabiting the southern and northern plateaus of Ethiopia. Twenty-one mtDNA haplotypes were identified. Geladas on the southern plateau were genetically separated from those on the northern plateau, with a large differentiation as indicated by Fst values of 0.665–0.917. The difference between the subspecies (T. g. gelada and T. g. obscurus) on the northern plateau highlighted a substantial genetic variation. Divergence times were estimated as ~250000 years between subspecies on the northern plateau and ~400000 years between those on the northern and southern plateaus. The genetic differentiation between the geographically distant Simien Mountain and Arsi groups (640 km) was ~2/3 of that between the geographically closer Debra Libanos and Arsi groups (250 km). The difference between subspecies within the northern plateau was similar to that between Papio hamadryas hamadryas and P. h. anubis. The difference between geladas in the north and south was similar to inter-subspecies differences in other mammals, and thus suggested that the Arsi geladas belong to subspecies T. g. arsi (tentative name). Considering the present distribution, geladas appear to have a complicated history of speciation. However, further analyses based on genetics, morphology and ecology are required to confirm these findings
