Phylogenetic tree of <i>Osedax</i> based on the concatenated analyses (Gblocked dataset) of <i>COI</i>, <i>16S</i>, <i>18S</i>, <i>28S</i>, and <i>H3</i> from Bayesian inference analysis (BI).

Squares on nodes refer to support retrieved from 4 different analyses: upper, left gblocked alignment under BI; upper right, complete alignment under BI; bottom left, gblocked alignment under ML; bottom right, complete alignment under ML. Green squares indicate posterior probability values (PP) > 0.95; bootstrap support (BS) > 95, yellow squares indicate 0.90 > PP < 0.95; 75 > BS < 95), red squares indicate clade recovered but below thresholds) and white indicates clade not recovered. Osedax deceptionensis and O. ‘mediterranea’ are indicated in bold. The six major Osedax clades previously defined by [11] and [12] are highlighted.
