Phylogenetic relationships of Rana wuyiensis sp. nov. and its relatives A maximum likelihood (ML) tree reconstructed based on the 16S, ND2 and Cyt b gene sequences B a part of the tree highlighting the relationships of the R. johnsi group. ML bootstrap supports/Bayesian posterior probability was denoted beside each node. Sample 1–44 refer to Table 1 C–E haplotype networks constructed based on sequences of nuclear genes BDNF, RAG1, and Tyr, respectively. Different species of the R. johnsi group were denoted as different colors.
