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.

自奇庞吉猴（Rungwecebus kipunji）——一种地理分布受限且极危的非洲猴类——被首次描述以来的四年间，其分类学地位一直饱受争议。近期有研究指出，首个Rungwecebus属的凭证标本（voucher specimen）携带狒狒的线粒体DNA（mitochondrial DNA），这一发现进一步加剧了相关争论。本研究表明，来自坦桑尼亚第二处分布区的Rungwecebus种群拥有独特的线粒体单倍型（haplotype），该单倍型位于包含所有狒狒属（Papio）物种以及首批Rungwecebus属凭证标本在内的演化支（clade）的基部分支，这一结果支持将Rungwecebus属确立为狒狒属的姊妹群（sister taxon），并确认其作为独立属的分类地位。我们推测，南部高地的Rungwecebus种群经历了来自狒狒属的地理局域性线粒体DNA基因渐渗（introgression），而恩杜杜卢（Ndundulu）种群则保留了真正的Rungwecebus属线粒体基因组。
