Description
Summary:DEAR EDITOR, Currently, the genus Polypedates comprises 26 species distributed in South, Southeast, and East Asia. Because of their relatively low dispersal capability and intolerance to seawater, this genus is ideal for the study of terrestrial range evolution that extends into the island archipelagos of southeastern Asia. Polypedates has diversified since the Oligocene (Li et al., 2013). [...]it seems that the dispersal processes of Polypedates can be attributed to a series of paleotectonic and paleoclimatic events, including the Indian-Eurasian collision, uplift of Himalayas, and Pleistocene climate oscillations with their associated sea-level fluctuations. [...]the routes and timing of migrations within this genus remain obscure. According to our results and previous studies (Buddhachat & Suwannapoom, 2018; Grosjean et al., 2015; Kuraishi et al., 2013; Rujirawan et al., 2013; Sutthiwisesa et al., 2020), the P. leucomystax complex is composed of seven groups: P. leucomystax, P. megacephalus, P. mutus, P. braueri, P. discantus, P. impresus, and P. teraiensis.
