Mito-phylogenetic relationship of the new subspecies of gentle monkey , Butynski & De Jong, 2020.

In 2020, a new subspecies was described in the complex, the Manyara monkey , Butynski & De Jong, 2020. The internal taxonomy of this species complex is still debated, and the phylogenetic relationships among the taxa are unclear. Here we provide the first mitochondrial sequence data for to determine its position within the mitochondrial phylogeny of . This subspecies clusters within the youngest (internal divergences between 1.01 and 0.42 Ma) of three main taxonomic clades of . Its sister lineages are (Ethiopia), (Kenya and Somalia), (Kenya and Tanzania), and (Tanzania and Mozambique). In general, the phylogenetic tree of based on mitochondrial sequence data indicates several paraphyletic relationships within the complex. As in other African cercopithecines (e.g. and ), these data are suitable for reconstructing historic biogeographical patterns, but they are only of limited value for delimitating taxa.
