As one of the most diverse genera of Cyprinidae, investigating the phylogeny and biogeography of <i>Garra</i> remains challenging. In this study, we combined sequences of <i>Garra</i> samples collected from Myanmar with sequences downloaded from GenBank to investigate the phylogeny, diversification, and biogeography of <i>Garra</i> on a global scale, with an emphasis on Southeast Asia. Species delimitation results indicated that there are at least 22 potential species, including eight undescribed species in Myanmar, suggesting that the diversity of <i>Garra</i> in this region have been largely underestimated.
