Best-scoring ML tree (–lnL = 7193.942769) based on COI data from marine and freshwater rhinebothriids. Numbers on internal branches denote nodal support as inferred by Bootstrap Proportions based on 5,000 replicates. *, indicates nodes recovered during phylogenetic analysis under parsimony. Numbers between square brackets in front of terminals represent total length in millimeters for those specimens measured. Scale indicates expected number of substitution per site. |
