Combined Bayesian (BEAST) and Maximum likelihood (iqtree) phylogenetic tree of all Watersipora COI sequences available on Genbank (With accession number and corresponding source references). Numbers at the nodes correspond to the posterior probabilities from the ‘BEAST’ analysis followed by the ultra-fast bootstrap values from ‘iqtree’, both expressed as percentages (i.e., 100/100). Only one accession number was listed per species for redundant sequences (number identical of sequences in parenthesis). New sequences acquired in this study are indicated by *. Color coding refers to species names listed on Genbank. Corrected identification (See Suppl. materials 1, 3: table S1 and fig. S1) are: Clade 1 W. arcuata; Clade 2 W. subtorquata; Clade 3 “Watersipora sp. sensu Mackie et al., (2012)”; Clade 4 “W. edmondsoni”; Clade 5 W. subatra.
