Abstract
OBJECTIVES Incomplete and/or biased sampling either on a taxonomic or geographic level can lead to delusive phylogenetic and phylogeographic inferences. However, a complete taxonomic and geographical sampling is often and for various reasons impossible, particularly for widespread taxa such as baboons (Papio spp.). Previous studies on baboon phylogeography identified several sampling gaps, some of which we fill by investigating additional material including samples from museum specimens. MATERIALS AND METHODS We generated 10 new mitochondrial genomes either via conventional PCR and subsequent Sanger sequencing from two blood samples or via high-throughput shotgun sequencing from degraded DNA extracted from eight museum specimens. Phylogenetic relationships and divergence times among baboon lineages were determined using maximum-likelihood and Bayesian inferences. RESULTS We identified new mitochondrial lineages in baboons from Central Africa (Chad, the Central African Republic), from the Mahale, and the Udzungwa Mountains (Tanzania), with the latter likely representing a case of mitochondrial capture from sympatric kipunjis (Rungwecebus kipunji). We also found that the mitochondrial clades of olive baboons found in Ivory Coast and Tanzania extend into Niger and the Democratic Republic of Congo, respectively. Moreover, an olive baboon from Sierra Leone carries a mitochondrial haplotype usually found in Guinea baboons, suggesting gene flow between these two species. DISCUSSION The extension of the geographic sampling by including samples from areas difficult to visit or from populations that are most likely extirpated has improved the geographic and temporal resolution of the mitochondrial phylogeny of baboons considerably. Our study also shows the great value of museum material for genetic analyses even when DNA is highly degraded.

Abstract
Shennongjia Rhinopithecus roxellana (SNJ R. roxellana) is the smallest geographical population of R. roxellana. The phylogenetic relationships among its genera and species and the biogeographic processes leading to their current distribution are largely unclear. To address these issues, we resequenced and obtained a new, complete mitochondrial genome of SNJ R. roxellana by next‐generation sequencing and standard Sanger sequencing. We analyzed the gene composition, constructed a phylogenetic tree, inferred the divergence ages based on complete mitochondrial genome sequences, and analyzed the genetic divergence of 13 functional mtDNA genes. The phylogenetic tree and divergence ages showed that R. avunculus (the Tonkin snub‐nosed monkey) was the first to diverge from the Rhinopithecus genus ca. 2.47 million years ago (Ma). Rhinopithecus bieti and Rhinopithecus strykeri formed sister groups, and the second divergence from the Rhinopithecus genus occurred ca. 1.90 Ma. R. roxellana and R. brelichi diverged from the Rhinopithecus genus third, ca. 1.57 Ma. SNJ R. roxellana was the last to diverge within R. roxellana species in 0.08 Ma, and the most recent common ancestor of R. roxellana is 0.10 Ma. The analyses on gene composition showed SNJ R. roxellana was the newest geographic population of R. roxellana. The work will help to develop a more accurate protection policy for SNJ R. roxellana and facilitate further research on selection and adaptation of R. roxellana.
