The position of Leiognathidae in the Bayesian inference (BI) and maximum likelihood (ML) phylogenetic tree based on the amino acid sequences of 13 protein-coding genes of the mitochondrial genome and their groupings, clades, ecotypes, and lengths. The numbers above or below branches indicate ML bootstrap values and Bayesian posterior probabilities, respectively; “*” indicates absence from the maximum clade credibility tree; “-” indicates no support value. L. brevirostris (NC 026232) should be a species of Nuchequula, and L. ruconius (NC 057225) is not classified under Leiognathus in the NCBI database.
