The phylogenetic tree was constructed based on mitochondrial genome sequences of P. Innesi and 13 closely related species using the Maximum Likelihood (ML) method. The phylogenetic tree clearly illustrated phylogenetic relationshios of P. Innesi (Figure 1). The closely related species of P. Innesi was paracheirodon axelrodi, which confirmed that it indeed belong to genus Paracheirodon.
