摘要: 基于线粒体Cyt b基因部分序列，以波蛱蝶为外群，采用邻接法、最大简约法和贝叶斯法分别构建了中国线蛱蝶亚科10属25种蝶类的系统发育树，探讨了各主要类群间的系统发育关系。其结果表明，所有线蛱蝶亚科聚为两大枝：第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属，其中缕蛱蝶属与环蛱蝶族亲缘关系较近；第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属，其中线蛱蝶属为非单系群，翠蛱蝶属和律蛱蝶属则为单系发生，并构成姐妹群。Abstract: The present study investigated phylogenetic relationships of the subfalimy Limenitinae based on sequence data of the mitochondrial Cyt b gene of 25 species, covering 10 genera of the subfamily, using Ariadne ariadne as outgroup. Phylogenetic trees were reconstructed with neighbor-joining (NJ), maximum parsimony (MP) and Bayesian inference (BI) methods. It is indicated that the involved species of this subfamily clustered into two clades: the first clade includes those of the genus Neptis, Phaedyma,Pantoporia and Lintinga; the second one includes those of the genus Parthenos,Moduza,Limenitis, Athyma, Lexias and Euthalia. The genus Limenitis is suggested to be monophyletic; and the genera Euthalia and Lexias proved to be sister to each other and form a monophyletic group. The genus Litinga appears to be more closely related to Neptini than to Limenitini. However, phylogenetic positions of some genera, such as Phaedyma, Pantoporia and Lintinga, are not well-resolved in the present study.
