凤蝶亚科（凤蝶科，鳞翅目）16S rRNA基因的分子系统发生分析

Fragments of mtDNA 16S rRNA gene were sequenced for 15 species of Papilioninae butterflies. Combining with the homologous sequences of other species from the GenBank, the molecular phylogenetic trees of Papilioninae were reconstructed using neighbor-joining, maximum parsimony, maximum likelihood and bayesian methods. The results showed that the Lampropterini constituted a monophyletic group as the most basal branch in the molecular phylogenetic trees; the Troidini was monophyletic, clustering wihinin the Papilionini; the monophyly of Teinopalpini was uncertain. It is supported that Chilasa was one of the early diversifications from Papilionini according to the researches on molecular systematics, morphological features and the evidence of host-plants, and its divergence was very likely to be earlier than that of Troidini from both of their closest ancestor.
