Spotless tree toad

The spotless tree toad (Dryophytes immaculatus) is a species of frog in the family Hylidae endemic to Korea. Its natural habitats are temperate forests, temperate shrubland, temperate grassland, rivers, swamps, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, pastureland, rural gardens, open excavations, and irrigated land. It is threatened by habitat loss.

Until recently, Korean populations of the spotless tree toad were classified as a separate species and named the Suweon tree frog.[1]

The spotless tree toad and the Japanese tree frog, which is also found in the same region, are the only two hylid species found on the Korean Peninsula. Factors distinguishing them include the frequency of the call,[2] calling behavior,[3] webbing between the toes and the angle of the line between eyes and nostrils.[4]

The spotless tree toad is known to display high prevalence of Chytrid Fungus.[5] However, this frog has also been listed as an invasive species in the United States.[6]
