FIGURE 2. A, majority rule consensus tree of the Bayesian inference analysis of 2421 bp total of 16S (236 bp), 18S (1580 bp), 28S (287 bp) and Histone 3 (318 bp) of Boccardia, Pygospio and Rhynchospio sequences rooted with sequences of Marenzelleria. B, majority rule consensus tree of the Bayesian inference analysis of 2516 bp total of 16S (284 bp), 18S (1618 bp), 28S (293 bp), and Histone 3 (321 bp) of the only-Rhynchospio sequences. Posterior probabilities are shown on the branches. Species names are followed by the names of the collecting locations (in parentheses).
