Bayesian consensus tree of the mtDNA COI gene. The tree was rooted with Caprella linearis (FJ581571.1), Caprella mutica (FJ581578.1), Caprella septentrionalis (FJ581589.1), Caprella scaura (AB539699.1), Caprellidae sp. (EF989681.1), and Cyamus ovalis (DQ094901.1), sequences available in GenBank. Bootstrap values of nodes correspond to maximum parsimony, maximum likelihood (both above branches), and to Bayesian posterior probabilities (below branches), respectively (n.s. indicates less than 50 % support).
