Assignment of individuals to genetic cluster using the STRUCTURE algorithm for K = 2 (mean LogLikelihood across three runs, -ln = 595.9). The red color corresponds to the individuals sampled in the Nguru and Usambara Mts (albigula). Green corresponds to individuals sampled in the Tanzanian lowland (rabai) and Mozambique/Zimbabwe (debilis). Evidence for admixture involves five individuals sampled in the Nguru Mts, Usambara Mts and on Mt Kanga.
