Family-level phylogenetic relationships of the superfamily Sylvioidea have always been debated and the mitogenome data have a high probability of resolving intractable phylogenetic relationships. On the basis of mitogenome data, the family-level phylogenetic relationships ((((Pellorneidae, Leiothrichidae) Timaliidae) Zosteropidae) Sylviidae) among the superfamily Sylvioidea were strongly supported and Spizixos semitorques was nested within the genus Pycnonotus. We propose that the generic placement of Spizixos should be reconsidered.
