Phylogenetic tree including the six target heterophyid species from Vietnam (Centrocestus formosanus, Haplorchis pumilio, H. taichui, H. yokogawai, Procerovum varium and Stellantchasmus falcatus) and other opisthorchioid trematodes based on partial 28S rDNA sequences (1,100 bp). Alaria alata (Diplostomidae) was used as the outgroup taxon. The tree depicted was inferred using maximum likelihood (ML) analysis with the general time reversible (GTR) + G + I model (gamma rate heterogeneity and a proportion of invariant sites) in the MEGA 6.06 package. Support for each node was evaluated using 1,000 bootstrap resamplings [38]. An almost identical tree was found using Bayesian analysis (see text for details). Numbers at nodes are Bayesian posterior support values/ML bootstrap values. The basal node for the superfamily Opisthorchioidea is indicated by an arrow. The scale-bar indicates the number of substitutions per site. Accession numbers are given at the end of each sequence name
