From the IUCN Red List Species Account:

Range Description

This species is known only from the islands of Bali and Lombok in Indonesia, from above 1,000m asl.

Habitat and Ecology

It is known only from highland forest. It presumably lays eggs on the ground and breeds by direct development without a larval stage.

Population

There is no recent information on this species, and it has not been recorded since the 1930s.

Population Trend

Decreasing

Major Threats

The habitat of this species is being severely impacted by very large-scale international tourism.

Conservation Actions

The mountain forests on Bali are protected, but for recreational purposes, not for biodiversity conservation. On Lombok the species presumably occurs in Gunung Rinjani Nature Reserve. There is clearly an urgent need for survey work to establish the current population status of this species on the two islands, and its presence within existing reserves.
