<p>Bayesian (BI) and Maximum Parsimony (MP) trees inferred for specimens of <i>Eurythenes gryllus</i> sampled in this study, based on the combined dataset of three genes (COI, 16S rDNA, 28S rDNA), showing posterior probabilities (>0.5) and bootstrap values (>50%; number of bootstrap replicates = 2,000), respectively. Two bootstrap values are shown at each node, the upper one represents the value when gaps were treated as fifth characters whilst the lower one represents the value when gaps were treated as missing data. The different clusters are assigned with the codes Eg1–5. For each cluster, distributional ranges (ocean basin, bathyal vs. abyssal, depth) are indicated. The colored squares refer to the sample localities of <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0074218#pone-0074218-g001" target="_blank">Figure 1</a>.</p
