Bayesian tree for neobatrachian polystomes inferred from the analysis of four concatenated genes, namely 18S, 28S, COI and 12S. Numbers on nodes indicate Bayesian Posterior Probabilities. Indopolystoma spp. were regarded earlier as Polystoma spp. in Badets et al. [2] and Héritier et al. [22]. B. w. refers to Blommersia wittei and Z. s. to Zhangixalus smaragdinus. See also Table 1 for other host species. Scale bar represents 0.1 substitution/site.
