Molecular dating and biogeographic analyses. Maximum clade credibility tree from the relaxed molecular-clock analysis with exponential distribution and Birth and Death speciation process of ITS and ETS sequences in BEAST. Numbers refer to the supported nodes (Table 3). Pie charts (shown only for supported nodes, Table 3) reflect the relative probability of each area or combination of areas being ancestral, according to the ancestral area reconstructions based on the BayArea + J model implemented in BioGeoBEARS. Letters correspond to the ancestral areas or combination of areas represented in the upper part of the figure. The figure was created by using http://maps-for-free.com/, QGIS_3.4, and Inkscape_0.92.3.
