Résumé
Additional file 1: Figure S1, stochastic mapping of all synapomorphies. Pie charts at nodes indicate the relative Bayesian posterior probability of each character state. Duplicated characters are those for which the mapping with the equal rates (ER) model was added as well. Characters missing are those that presented some non-applicable states, for which the analysis did not work. File S1, morphological data matrix in Nexus format used in this study. File S2, list of morphological characters used in the analyses. Table S1, table with full taxonomic sampling, including specimen accession numbers and ages.
