This species is endemic to the Japanese islands of Ishigakijima and Iriomotejima.
Habitat and Ecology
It occurs in broad-leaved evergreen forest and streams in mountains, and is also found in coastal areas.
There is no information on the population status of this species.
The major threat is habitat loss and degradation, due to logging and human settlement, particularly on Ishigakijima.
In Japan its range includes Iriomote Island which is now protected as a national park, although there is clearly a need for improved protection of forest habitats in these islands.
