From the IUCN Red List Species Account:

 

Range Description

This species is known from the mountains of southeastern Luzon Island and from southern Polillo Island in the Philippines between sea level to 1,000 m asl. It probably occurs more widely than current records suggest, especially in areas between known sites. Its extent of occurrence (EOO) is 18,581 km2 and it is considered to occur in four threat-defined locations.

Habitat and Ecology

This species inhabits lower montane and lowland forests, occasionally being found in human-modified habitats beside these forests. It prefers cool and unpolluted mountain streams and ephemeral pools, where its larvae have been observed, but they have also been observed in dry stream beds (Philippines Red List Assessment Workshop 2017).

Population

It is common in intact forest, but has a patchy distribution. Field surveys at the type locality in 2015 indicate that it is fairly common in its preferred habitat, especially in mountain streams (Philippine Red List Assessment Workshop May 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

The major threat is habitat loss due to small-scale shifting agriculture, expanding human settlements, wood collection for firewood and charcoal production, and illegal logging by commercial entities (Philippines Red List Assessment Workshop May 2017).

Conservation Actions

Conservation Actions
The species occurs in Mount Banahaw-San Cristobal Protected Landscape and Mount Isarog Natural Park.

Conservation Needed
The most important conservation measure for it is the continued designation of the protected areas.

Research Needed
More information is needed on this species' distribution, population status, ecology, and threats.

Red List Status

Data Deficient (DD)

Rationale

Listed as Vulnerable because its extent of occurrence (EOO) is 18,581 km2, it occurs in four threat-defined locations, and there is continuing decline in the quality of its habitat on Luzon Island in the Philippines.
