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.
自最初描述以来的四年中，地理上受限且极度濒危的非洲猴——肯氏长尾猴的分类学一直存在争议，最近的研究表明，鲁文佐里长尾猴的第一个凭证标本具有狒狒的线粒体 DNA，这加剧了争议。我们表明，来自坦桑尼亚第二个地区的鲁文佐里长尾猴具有独特的线粒体单倍型，该单倍型是包含所有狒狒物种和原始鲁文佐里长尾猴凭证标本的一个分支的基础，支持将鲁文佐里长尾猴归类为狒狒的姊妹分类群及其作为一个独立属的地位。我们建议，南部高地的鲁文佐里长尾猴种群经历了来自狒狒的地理上局部的线粒体 DNA 渗入，而恩敦杜卢种群保留了真正的鲁文佐里长尾猴线粒体基因组。
