The complete mitochondrial genome of Poecilia formosa (Actinopterygii: Cyprinodontiformes: Poeciliidae)

The complete mitochondrial genome sequence of the Poecilia formosa is first reported in this study. The length of genome is 16 550 bp, including 13 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes. Congeneric mitogenome sequence identity is 87.7% with P. reticulate and 93.1% with P. sphenops. The reconstructed phylogenetic relationships of 16 Cyprinodontiformes species based on 13 protein-coding genes were highly supported and the clade of all Poecilia fishes included had a support value of 100%. Our results shall provide a better understanding in the evolutionary histories of the Cyprinodontiformes.
