Figure 3. Phylogenetic hypothesis of Polynoidae inferred from a maximum likelihood analysis based on the reduced dataset of four concatenated genetic markers (18S rRNA, 28S rRNA, 16S rRNA and COI). Alignment was performed with MUSCLE for COI, using default parameters, and with MAFFT for 18S rRNA, 28S rRNA and 16S rRNA, using the xinsi option. Ambiguously aligned positions were removed with GBLOCKS. Support values in branches correspond, per order and separated by '/', to the bootstrap support (BS) values of the maximum likelihood IQ-TREE, the number of genes (concordance) and the numbers of positions (concordance). *Posterior probabilities> 0.9 recovered after Bayesian inference in MRBAYES.
