基于线粒体ND1和COI基因序列探讨锯眼蝶亚科主要类群的系统发生关系

测定了分布于中国的锯眼蝶亚科4族10属共20个种的线粒体ND1和COI基因的部分序列,结合从GenBank中获得的4个国外种类的同源序列,以凤蝶科的迪洛尔娟凤蝶(Allancatria deyrolle)、丝带凤蝶(Sericinus montela),以及娟蝶科的西猛娟蝶(Parnassius simonius)为外类群,通过邻接法、最大简约法、最大似然法和贝叶斯法重建了分子系统树,分析了该亚科内主要类群的系统发生关系。分析结果表明:帻眼蝶族和锯眼蝶族具有较近的亲缘关系;黛眼蝶族不是单系群,该族中的黛眼蝶属、荫眼蝶属与眉眼蝶族具有较近的亲缘关系,带眼蝶属、藏眼蝶属、毛眼蝶属和帕眼蝶属聚合为一个独立的支系,其中带眼蝶属和藏眼蝶属在所有的分析方法中均以100%的置信度(BP=100%,PP=1.00)相聚合,建议将它们合并为一属。

Phylogentic Relationships of Butterflies in the Subfamily Elymninae (Lepidoptera: Satyridae) Based on Mitochondrial ND1 and COI Gene Sequences

The fragments of the mitochondrial ND1 and COI gene of 20 Chinese species in the subfamily Elymninae were amplified and sequenced. Combining the homologous sequences of four foreign species from GenBank and using three species of the families Papilionidae and Parnassiidae as outgroups, phylogenetic trees of these Elymninae groups were reconstructed with neighbor joining, maximum parsimony, maximum likelihood and Bayesina inference methods. The results showed that the tribes Zetherini and Elymniini are closely related to each other. The tribe Lethini is not monophyletic, the genera Lethe and Neope are closely related to the tribe Mycalesini and the genera Chonala, Tatinga, Lasiommata and Pararge form a monophyletic clade. The genera Chonala and Tatinga were clustered together in all the trees and supported with a 100% bootstrap value or a posterior probability of 1.00, and should be classified as one genus.
