Nucleotide sequences were aligned using MAFFT v7 (https://mafft.cbrc.jp/alignment/software/), and use ModelFinder (ModelFinder is implemented in IQ-TREE version 1.6.1.2, http://www.iqtree.org) to calculate the best model (K2P + G4 model was selected based on Bayesian Information Criterion: BIC). Bayesian inference (BI) and Monte Carlo Markov Chain (MCMC) methods were used to construct the phylogenetic tree in PhyloSuite v1.2.2 (https://github.com/dongzhang0725/PhyloSuite/ releases), The number of substitutions (Nst) was set at two, and posterior probability values were calculated by running 2,000,000 generations with four simultaneous tree-building chains. A 50% majority-rule consensus tree was constructed from the final 75% of the trees generated by BI. Analyses were run three times to ensure convergence and insensitivity to priors. Phylogenetic tree were edited in Figtree v1.4.3 (https://github.com/rambaut/figtree/releases).
