Neighbor-joining tree on the basis of ITS2 sequences of cercarial species obtained from Thai populations of Tarebia granifera (Lamarck, 1816) and several published sequences obtained from GenBank. Nodes are annotated with bootstrap support values ≥ 50. Taxon names and voucher or GenBank accession numbers are provided at the tips of the tree (see also Table 1). First and second intermediate hosts and definitive hosts are indicated (see legend). Abbreviations – DH: definitive host: IH1: first intermediate host; IH2: second intermediate host. Cercarial types – a: virgulate xiphidiocercariae; b: armatae xiphidiocercariae; c: gymnocephalous cercariae; d: echinostome cercariae; e: megarulous cercariae; f: parapleurophocercous cercariae; g: pleurophocercous cercariae.
