Characterisation of fascioliasis lymnaeid intermediate hosts from Chile by DNA sequencing, with emphasis on Lymnaea viator and Galba truncatula

► rDNA and mtDNA sequencing and phylogeny of fascioliasis lymnaeid hosts in Chile. ► Authochthonous Lymnaea viator and introduced Galba truncatula are main transmitters. ► Lymnaea lebruni and L. patagonica proved to be synonyms of Pectinidens diaphana. ► Distribution of G. truncatula appears related to areas with higher human and animal prevalences. ► Overlap of species explain lack of correlation between remote sensing data and prevalences.
