Asterisks indicate the highest support values obtained by all three inference methods. GenBank accession numbers for the concatenated sequences (18S rDNA, tufA and rbcL, respectively) accompany each species name. Newly obtained sequences are given in bold. Scale bar shows the estimated number of substitutions per site.

Posterior Probabilities (PP) and bootstrap support values (BS, RAxML-NG analysis) are represented on branches leading to nodes on the left and right, respectively. Branches in bold had a significant statistical support (PP ≥ 0.95; BS ≥ 70 %).
