Using Parantica aglea and Euploea core as the outgroups, the phylogenetic trees of the Nymphalidae taxa in this study were reconstructed with and Bayesian methods based on 16S rDNA, 12S rDNA and their combined sequences. The results showed that the Nymphalinae was not monophyletic; the Junonia should be classified into Hypolimni; the Apaturinae, Byblinae and Nymphalinae were closely related to each other; the Pseudergolinae and Byblinae should be separated from Limenitinae.
