Rallidae, with 34 genera including 142 species, is the largest family in the Gruiformes, the phylogenetic placement of this family was still in debate. The complete mitochondrial genomes (mitogenomes), with many advantageous characters, have become popular markers in phylogenetic analyses. We sequenced the mitogenomes of brown crake (Amaurornis akool) and white-breasted waterhen (Amaurornis phoenicurus), analyzed the genomic characters of mitogenomes in Rallidae, and explored the phylogenetic relationships between Rallidae and other four families in Gruiformes based on mitogenome sequences of 32 species with Bayesian method. The mitogenome of A. akool/A. phoenicurus was 16,950/17,213 bp in length, and contained 37 genes typical to avian mitogenomes and one control region, respectively. The genomic characters of mitogenomes in Rallidae were similar. The phylogenetic results indicated that, among five families, Rallidae had closest relationship with Heliornithidae, which formed a sister taxa to Gruidae, while Rhynochetidae located in the basal lineage. Within Rallidae, Rallina was ancestral clade. Gallirallus & Rallus and Aramides were closely related, Gallicrex & Amaurornis and Fulica & Gallinula had close relationships, and these two taxa formed a sister clade to Porphyrio & Coturnicops. Our phylogenetic analyses provided solid evidence for the phylogenetic placement of Rallidae and the evolutionary relationships among different genus within this family. In addition, the mitogenome data presented here provide useful information for further molecular systematic investigations on Gruiformes as well as conservation biology research of these species.
