Fig. 3

Maximum Likelihood (ML) tree/Bayesian Inference (BI) tree constructed by concatenated genes (COX1 + 16S rRNA + 28S rRNA). The trees built by ML (See Supplementary Fig. 1, Additional file 2) and BI (See Supplementary Fig. 2, Additional file 2) have been combined. The numbers at the internodes are the maximum likelihood bootstrap proportions and bayesian inference posterior proportions. The positions of the species morphology in the figure correspond to the species name on the phylogenetic tree. Information on the sequences and numbers is provided (See Supplementary Table 2, Additional file 1)
