Abstract

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.

非洲细翅蝶属的系统学与进化(鳞翅目，蝶科)

基于COI、EF1a、GAPDH、MDH、RpS5和无翅6个基因区，研究了非洲热带蝴蝶Mylothris属(鳞翅目:蝶科)的系统学和进化史。我们发现该属可分为五个种群，分别称为jacksoni, elodina, rhodope, agathina和hilara组。在这些物种群中，我们发现基于我们测序的标记，许多物种表现出很少的遗传分化，这表明它们经历了快速和近期的物种形成。基于二次校准，我们估计Mylothris冠群的年龄约为1600万年，但许多物种水平的分歧发生在更新世。我们推断该分支起源于中非东部的森林，并从那里扩散到非洲的其他地区。

期刊介绍： Nota Lepidopterologica is the scientific, peer-reviewed journal of the Societas Europaea Lepidopterologica (SEL). It publishes original contributions to the study of mainly but not exclusively Palaearctic Lepidoptera, especially on taxonomy, morphology/anatomy, phylogenetics, biogeography, ecology, behaviour, and conservation, but also on any other aspects of lepidopterology. All articles are published in English, with the possibility of having the summary written in other languages. All submitted manuscripts are subject to peer-review by the leading specialists for the respective topic. The journal is published in open access high-resolution PDF, semantically enriched HTML and machine-readable XML versions. All papers can be freely copied, downloaded, printed and distributed at no charge. Authors and readers are thus encouraged to post the pdf files of published papers on homepages or elsewhere to expedite distribution. Publication is free for the SEL members and there is no charge for color.
