This paper investigated phylogenetic relationships within the Muscicapinae based on analysis of cytochrome b mitochondrial gene sequences involving 992 bp of 31 species representing 6 putative Muscicapinae genera.Lanius isabellinus and Dicrurus hottentottus were selected as outgroups.Phylogenetic trees were reconstructed using methods of Bayesian(BI),maximum-likelihood(ML)and maximum parsimony(MP).The results suggest to move Terpsiphone from Muscicapinae to Monarchidae.Rhipidura and Culicicapa should be placed into the Rhipiduridae from Muscicapinae.Both Muscicapa and Niltava are monophyletic taxa,and Muscicapa is the sister-group and a close relative of the Niltava clade.Ficedula is not monophyletic,and the status of Ficedula zanthopygia is different in the three putative phylogenetic trees,so that the analysis did not confidently resolve the status of this species.The results also indicate that Muscicapa thalassina is closely related to Cyanoptila cyanomelana,and they should be placed in Niltava or be the sister genus to Niltava.These results resolve the phylogenetic relationships among some controversial genera and species of Muscicapinae,and provide a molecular phylogenetic evidence for taxonomic research of Muscicapinae.
