The haplotype networks of five  species groups (“species endemic to Inle Lake”) generated with the TCS algorithm, based on COI regions (640 bp). Each bar on a branch corresponds to a single nucleotide substitution. Small dots represent hypothetical haplotypes. A Inlecypris auropurpureus obtained from Hopong and two other localities. B Microrasbora rubescens obtained from Hopong and two other localities. The Heho specimens were obtained from a local market and their original locality is unknown. C Physoschistura brunneana and P. rivulicola obtained from Hopong and two other localities. The Heho specimens were obtained from a local market and their original locality is unknown. D Sawbwa resplendens obtained from Hopong and Inle Lake. E Petruichthys brevis obtained from Hopong and two other localities and Petruichthys sp. obtained from Hopong.
