. We study the systematics and evolutionary history of the Afrotropical butterfly genus Mylothris (Lepidoptera: Pieridae) based on six gene regions (COI, EF1a, GAPDH, MDH, RpS5 and wingless). We find that the genus can be placed into five species groups, termed the jacksoni, elodina, rhodope, agathina and hilara groups. Within these species groups, we find that many species show very little genetic differentiation based on the markers we sequenced, suggesting they have undergone rapid and recent speciation. Based on secondary calibrations, we estimate the age of the crown group of Mylothris to be about 16 million years old, but that many of the species level divergences have happened in the Pleistocene. We infer that the clade has its origin in the forests of the Eastern part of Central Africa, and has spread out from there to other regions of Africa.

非洲蝴蝶属Mylothris（鳞翅目，Pieridae）的系统学和进化

。我们研究了基于六个基因区域（COI，EF1a，GAPDH，MDH，RpS5和无翅）的亚热带蝴蝶属Mylothris（鳞翅目：Pieridae）的系统学和进化史。我们发现该属可分为五个物种组，分别称为波克，波罗的海，罗多彼，罗汉果，agathina和hilara。在这些物种组中，我们发现许多物种根据我们测序的标记显示出极少的遗传分化，这表明它们已经经历了快速的近代物种形成。根据二次定标，我们估计Mylothris冠群的年龄大约为1600万年，但是在更新世中已经发生了许多物种水平的差异。我们推断该进化枝起源于中非东部的森林，
