Data from: The biogeography of introgression in the critically endangered African monkey Rungweceubs kipunji

In the four years since its original description, the taxonomy of the
kipunji (Rungwecebus kipunji), a geographically restricted and critically
endangered African monkey, has been the subject of much debate, and recent
research suggesting that the first voucher specimen of Rungwecebus has
baboon mitochondrial DNA has intensified the controversy. We show that
Rungwecebus from a second region of Tanzania has a distinct mitochondrial
haplotype that is basal to a clade containing all Papio species and the
original Rungwecebus voucher, supporting the placement of Rungwecebus as
the sister taxon of Papio and its status as a separate genus. We suggest
that the Rungwecebus population in the Southern Highlands has experienced
geographically localized mitochondrial DNA introgression from Papio, while
the Ndundulu population retains the true Rungwecebus mitochondrial genome.
