Garra is a kind of small- to medium-sized fish that is widely
distributed from southern Eurasia to central Africa. As one of the most
diverse genera of Cyprinidae, investigating the phylogeny and
biogeography of Garra remains challenging. In this study, we combined
sequences of Garra samples collected from Myanmar with sequences
downloaded from GenBank to investigate the phylogeny, diversification,
and biogeography of Garra 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 Garra in this region have been
largely underestimated. Diversification analysis suggested a relatively
high diversification rate in the early branches of Garra. Ancestral
distribution reconstruction results revealed that Garra originated from
the Southeast Asia in the late Eocene, approximately 34 million years
ago, with subsequent dispersals across different drainages influenced by
the uplift of the Qinghai-Tibet Plateau. Our study provided a new
insight into the evolutionary history of Garra and the basis for further
research on this genus.02 Sep 2024Submitted to Ecology and Evolution 05 Sep 2024Submission Checks Completed
