This species is known only from the montane forest between Layang Layang and Pakka Cave on the southwestern slopes of Kinabalu National Park, Sabah, Malaysia. It has been recorded at elevations of 2,200–3,050 m asl and its estimated extent of occurrence (EOO) is 22 km2. It is likely to be very restricted in its distribution.
Habitat and Ecology
This is a montane forest species occurring in mossy forest at the lower elevation parts of its range (below 2,600 m asl). The eggs and larvae of this species have been found in pitcher plants (Nephenthes sp.). This species breeds by direct development.
It is easy to find and is common where it occurs, and the population is considered to be stable (P. Yambun pers. comm. January 2018).
There are no known threats to this species since it is only know from a well-protected and well-managed national park (P. Yambun pers. comm. January 2018).
This species is known only from Kinabalu National Park.
Continuation of rigorous management of the existing parks to protect forest habitat is the best guarantee for the conservation of this species.
Surveys of potentially suitable areas of habitat in adjacent parts of Borneo are needed to determine whether or not this species might occur elsewhere, and also to help better understand its current population status. There is a need for taxonomic research for all Philautus species occurring in Malaysian Borneo.
Red List Status
Listed as Least Concern since, although its estimated extent of occurrence (EOO) is 22 km2, it occurs entirely within a well-protected and well-managed national park, where suitable habitat remains, and there are no threats to the species.
