Bayesian inference dendrogram of Ophryophryne (including other megophryid outgroups) derived from the analysis of a 2077 bp DNA sequences of the 12S rRNA–16S rRNA mtDNA gene. Voucher specimen IDs and GenBank accession numbers are given in Table 1. Numbers near branches represent BPP/BS support values for BI/ML inferences respectively. Color of clade labels for Ophryophryne corresponds to icon colors on Fig. 1. I and II represent Group I and Group II defined in the results section; numbers 1, 2 and 3 next to nodes in Group II represent species level clades; A–E represent subclades within species level clades.
