From the IUCN Red List Species Account:


Range Description

This species is known only from Mount Ungaran, Central Java, Indonesia.

Habitat and Ecology

It presumably inhabits montane forest, and is believed to be a direct-developer, not dependent upon water.


It is known only from the holotype, and has not been recorded for over 90 years, so it might already be extinct (particularly if genuinely confined to the type locality).

Population Trend


Major Threats

Forest loss at the type locality has been so severe that almost no habitat remains.

Conservation Actions

It has not been recorded from any protected areas. Surveys are needed to determine whether or not this species still survives in the wild.
