非洲绿色猴（Chlorocebus）是撒哈拉以南非洲分布广泛、形态多样的灵长类动物。但对它们的遗传多样性和亲缘关系研究较少。根据形态学资料，目前已知有6个种，但它们的分类仍有争议。在这里，我们的目标是表征线粒体（mt）DNA多样性，非洲绿色猴的遗传学。我们分析了完整的线粒体细胞色素B基因的126个样品，使用粪便从野生个体和材料从动物园和博物馆标本具有明确的地理来源，包括几个模式标本。我们发现了9个主要mtDNA分支的证据，反映了地理分布，而不是类群，这意味着非洲绿色猴的mtDNA多样性不符合现有的分类学分类。进化枝之间的系统发育关系不能得到解决，这表明一个快速的早期分歧的血统。线粒体DNA和表型之间的一些不一致性表明，杂交可能发生在物种之间的接触区，包括受威胁的巴莱猴（Chlorocebus djamdjamensis）。本研究结果为非洲绿色猴的遗传多样性和进化提供了有价值的数据，也为进一步开展该属的分子生物学研究奠定了基础。Am.

African green monkeys (Chlorocebus) represent a widely distributed and morphologically diverse primate genus in sub-Saharan Africa. Little attention has been paid to their genetic diversity and phylogeny. Based on morphological data, six species are currently recognized, but their taxonomy remains disputed. Here, we aim to characterize the mitochondrial (mt) DNA diversity, biogeography and phylogeny of African green monkeys. We analyzed the complete mitochondrial cytochrome b gene of 126 samples using feces from wild individuals and material from zoo and museum specimens with clear geographical provenance, including several type specimens. We found evidence for nine major mtDNA clades that reflect geographic distributions rather than taxa, implying that the mtDNA diversity of African green monkeys does not conform to existing taxonomic classifications. Phylogenetic relationships among clades could not be resolved suggesting a rapid early divergence of lineages. Several discordances between mtDNA and phenotype indicate that hybridization may have occurred in contact zones among species, including the threatened Bale monkey (Chlorocebus djamdjamensis). Our results provide both valuable data on African green monkeys' genetic diversity and evolution and a basis for further molecular studies on this genus. Am. J. Primatol. 75:350-360, 2013.
