FIGURE 6. Maximum likelihood tree inferred from concatenated sequences of nuclear 18S and 28S and mitochondrial 16S rRNA gene sequences of Polydora species obtained in this study and from DDBJ/EMBL/GenBank database (Table 1). The gene sequences obtained in this study are highlighted in boldface. SH-aLRT/approximate Bayes support/ultrafast bootstrap support values of ≥80%/≥0.95/≥95%, respectively, are given beside the respective nodes. Nodes with red circles indicate triple high support values of SH-aLRT ≥ 80, approximate Bayes support ≥ 0.95, and ultrafast bootstrap support ≥ 95. The scale bar represents the number of substitutions per site. Sequences of Dipolydora species are used for outgroup rooting. The symbols at the left of the species names indicate the lifestyle based on the available information (Table 1).
