Podicipediformes comprises one family (Podicipedidae) including 6 genera, 22 species, and the phylogenetic placement of this order was still in debate. In this study, we sequenced the complete mitochondrial genome (mitogenome) of little grebe (Tachybaptus ruficollis) in Podicipediformes, and explored the phylogenetic position of this order with mitogenome sequences of 21 species from ten families in seven orders. The genome was 16,688 bp in length, and contained 37 genes typical to avian mitogenomes and one control region. The gene organization and characters were similar with other two mitogenomes available in Podicipediformes to date. Phylogenetic tree was constructed with Bayesian method based on mitogenome sequences excluding the control regions. The results supported the closest relationship between Podicipediformes and Phoenicopteriformes, and the topology of our tree was generally similar with the conclusions of previous molecular systematic investigations. Our results furtherly proved the validity of mitogenome data in taxonomic and phylogenetic studies.
