Phylogenetic relationships among the Microhyla berdmorei species group and other related Microhyla species based on single gene sequences. A: Nuclear allele median-joining network of BDNF gene haplotypes (716 bp) sequenced in the Microhyla berdmorei species group. Circle sizes are proportional to the number of samples/sequences (n); small open circles indicate hypothetical haplotypes (alleles). B: ML-tree of Microhyla derived from the analysis of 3119 bp of concatenated alignment including 12S rRNA, tRNAVal, 16S rRNA, and COI mtDNA gene fragments. Full version of this tree is presented in Figure S1. For voucher specimen information and GenBank accession numbers see Table S1. Numbers at tree nodes correspond to ML UFBS / BI PP support values, respectively. Values at tree nodes in square brackets correspond to the median divergence times as estimated in BEAST, which are detailed in Figure S2. Colors of the circles in the network and the mitochondrial lineages in the tree correspond to the colors used in Figures 1–5. Photographs by A. V. Trofimets, A. M. Bragin, P. Pawangkhanant and N. A.
