Supplementary Materials
SM.01. Information about collection data of 127Milnesium spp. populations utilised in the study.
SM.02. GenBank accession numbers for all Milnesium spp. sequences used in the analyses. New sequences are bolded.
SM.03. The Bayesian Inference phylogenetic tree based on concatenated 18S rRNA+28S rRNA+ITS-2+COI nucleotide sequences obtained with MrBayes. Values at nodes represent posterior probability (PP) supports. Scale bar shows the number of substitutions per site.
SM.04. The results of the RASP analysis of geographic origin of the ancestor, based on the Bayesian Inference phylogenetic tree based on concatenated 18S rRNA+28S rRNA+ITS-2+COI nucleotide sequences obtained with BEAST.
SM.05. The results of the RASP analysis of climate type of the main clades, based on the Bayesian Inference phylogenetic tree based on concatenated 18S rRNA+28S rRNA+ITS-2+COI nucleotide sequences obtained with BEAST.
