The Cercopithecini, or African guenon monkeys, are one of the most diverse clades of living primates and comprise the most species-rich clade of Catarrhini. Species identity is announced by flamboyant coloration of the facial and genital regions and, more cryptically, by vigorous chromosomal rearrangements among taxa. Beneath the skin, however, these animals are skeletally conservative and show low levels of genetic sequence divergence consonant with recent divergence between congeneric species. The guenons clearly demonstrate that morphological, cytogenetic, and reproductive differentiation proceed at different rates during speciation. We review diverse kinds of data in an effort to understand this conundrum.
猕猴族，即非洲长尾猴，是现存灵长类动物中最多样化的进化枝之一，也是狭鼻小目（旧世界猴）中物种最丰富的进化枝。物种身份通过面部和生殖器区域的艳丽色彩来彰显，更隐秘的是，通过类群间剧烈的染色体重排来体现。然而，在皮肤之下，这些动物在骨骼结构上较为保守，并且基因序列差异水平较低，这与同属物种之间的近期分化相一致。长尾猴清楚地表明，形态、细胞遗传学和生殖分化在物种形成过程中以不同的速度进行。我们回顾了各种数据，试图理解这一难题。
