From the IUCN Red List Species Account:

Range Description

This species is known from the summit of Batu Linanit, Gunung Murud, Sarawak, East Malaysia (northwestern Borneo), at 2,250 m asl (Das 2008). It is likely a summit specialist, known from an area smaller than 1 km² (I. Das pers. comm. 2009). It occurs in one threat-defined location and its estimated extent of occurrence (EOO) is 10 km².

Habitat and Ecology

This species occurs in rhododendron forests, and is associated with Nepenthes and other fleshy plants (I. Das pers. comm. March 2018). Individuals have been found at night, up to 15 cm above the forest substrate, at the edge of forest trails on exposed, wind-swept slopes. Males have been observed calling from leaves near the ground (Inger et al. 2017). The tadpole is unknown, but the species is suspected to breed in pitchers of Nepenthes plants (Das 2008).

Population

It is an uncommon species (I. Das pers. comm. March 2018). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

Even though its type locality is within the recently gazetted Pulong Tau National Park, it is subject to subsistence logging (I. Das pers. comm. March 2018). The habitat in Pulong Tau National Park faces encroachment from logging companies, as it has only been recently gazetted (in the last 2-3 years) and there is no current infrastructure or field staff in place, so it is not well protected at present (I. Das pers. comm. March 2018). Clear-felling and large-scale logging concessions are also happening within parts of the national park, although the type locality of this species lies just outside the range of commercial hardwoods (I. Das pers. comm. 2009). Climate change is likely to be a future threat (I. Das pers. comm. March 2018).

Conservation Actions

Conservation Actions 
The species occurs within Pulong Tau National Park, which has only been recently gazetted (in the last 2-3 years) and there is no current infrastructure or field staff in place, so it is not well protected at present (I. Das pers. comm. March 2018).

Conservation Needed
Enforcement of the park's boundaries is needed to address logging issues within the park (Malaysia Red List Assessment Workshop March 2018).

Research Needed
Further research is needed into the life history and ecology of this species.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered, as a precautionary approach, because its extent of occurrence (EOO) is 10 km², it occurs in a single threat-defined location, and there is a continuing decline in the extent and quality of its habitat in the Gunung Murud area due to logging activities. Pulong Tau National Park has only recently been gazetted and there is no infrastructure in place to provide habitat protection at present.
