Mean posterior probability value of species delimitation models. The priors Θ and τ refer to the ancestral population size and age of root respectively. The bars indicate standard deviation. a. A four-species model and different number of loci for priors on Θ and τ. Loci: 1 - CO1; 2 - CO1, PGD, 3 - CO1, PGD, ITS; 4 - CO1, PGD, ITS, 28S. b. Analyses using all four genes resulted in highest support for the four-species model followed by the five-species model. c. Analyses using all four genes but only including the Asecodes specimens infesting G. tenella and G. calmariensis from the sympatric population in the northern part of Sweden (but including all other specimen infesting G. sagittaria, G. lineola and G. pusilla).
