This species is widely distributed in Ryukyu Islands and Amami Islands in Japan. It is found on most of the islands from the Tokara Archipelago on the north to the Yaeyama Archipelago in the south. It is introduced to Suwanosejima in the Tokara Group, Taramajima of the Miyako Group, and Kuroshima of the Yaeyama Group.
Habitat and Ecology
It is a common species through most of its range.
Globally there are no major threats to this species. It might be locally threatened by agrochemical pollution (land and water) and the conversion of habitat to intensively cultivated land.
It occurs in a number of protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
We follow Matsui et al. (2005) in separating this species from Microhyla ornata.
