Strict consensus tree from MrBayes output with BayesTraits ancestral state reconstructions for gill types. Gill types are illustrated on the left and assigned a color, which are assigned to taxa on the right-hand side of the tree. The posterior probability is shown on those nodes with a posterior probability below 1.0. Unlabelled nodes have a posterior probability of 1.0. In nodes with bootstrap support <70 in the IQTree ML inference, the bootstrap values are shown after the posterior probability for the respective node. Pie charts with the probabilities for the various gill types ancestral states are connected to their assigned node via numbered lines.
