Molecular phylogenetic relationships of Pethia, based on Bayesian inference of the concatenated cytb + rag1 (2572 bp) data set. Asterisks (*) above and below nodes represent ≥ 95% Bayesian posterior probabilities and ML bootstrap values, respectively. Scale bar represents number of changes per site. Node support below 50 is not labeled. Results of the molecular species delimitation methods (PTP, mPTP and ABGD) for cytb are shown as grey rectangles on the right. The results of the ABGD shown are based on the initial partition using the p-distance model at p =  ~ 0.01 and X = 1.5. The GenBank sample “P. meingangbii” is represented by only a rag1 sequence (KJ548126) and is not included in the species delimitation analyses. In the mPTP analysis, P. nigripinna (MG199967) and “Pethia sp.” (MT483288) were delimited as a single species
