a Sampling localities for Pethia nigrofasciata for the molecular analysis in the present study. Numbers on the map represent the sampling localities listed in Table 1. Median-joining haplotype network for P. nigrofasciata, based on the analysis of b a 1082 bp fragment of the cytb gene, and c a 1490 bp fragment of the rag1 gene. The number of mutational steps > 1 is indicated in parentheses. The black circles are hypothetical nodes. Legend colours correspond to river basins
