Bayesian inference phylogram based on concatenated cox1, 16S and ITS2 sequences. The two outgroups have been removed a posteriori. Bayesian posterior probabilities are provided next to each node (top: MrBayes, bottom: RAxML). Sequences obtained from GenBank are labelled as GB1–GB8 (see Table 1). Nodes 1 and 2 indicate the nodes for which divergence time estimates are discussed. Colour codes used for species represent the origin of African samples and refer to those used in the map in Fig 1. Shell images are from Galba truncatula (Morocco, Gtr25298) and Galba mweruensis (Tanzania, Gmw25316). The scale-bar indicates substitutions per site according to the applied models of sequence evolution
