Phylogenetic relationships inferred using maximum-likelihood (ML) and Bayesian (BI) analyses of the COI dataset (840 bp). Topology corresponds to best-scoring ML tree; node values are bootstrap scores (≥75%) / BI posterior probabilities (≥0.95). Taxa examined in this study are in bold. Stichopus horrens KY986418 was set as outgroup.
