Bayesian inference (BI) and maximum likelihood (ML) phylogram reconstructed using the partial 28S rDNA sequences for species of the Echinochasmidae and Echinostomatidae. Nodal support from BI and ML analyses indicated as BI/ML; only values > 0.90 (BI) and > 70 (ML) are displayed. The scale-bar indicates expected number of substitutions per site. Novel sequences are shown as the GenBank accession number followed by species name and fish host name. Names of trematode species presented next to coloured vertical bars.
