This Bornean endemic is known only from the montane forests of Mount Kinabalu in Kinabalu National Park, Sabah, Malaysia. Its elevational range is 1,500–3,050 m asl and its extent of occurrence (EOO) is 338 km2.
Habitat and Ecology
It is confined to submontane and montane forests and breeds by direct development. Its adaptability to secondary habitats is not known.
This species is common along the summit trail to Mt. Kinabalu (P. Yambun pers. comm. Jan 2018). It is commonly heard calling at night, especially after heavy rains (P. Yambun pers. comm. January 2018). The population is considered to be stable (P. Yambun pers. comm. January 2018).
There are no major threats to the species at present, as Kinabalu National Park is well-protected (P. Yambun pers. comm. January 2018). The 2015 Sabah earthquake (Earth Observatory of Singapore 2017) did not appear to affect this species because it is found mostly along the summit trail, whereas the landslides generally occurred at the rock faces and primarily affected species occurring closer to Mesilau (P. Yambun pers. comm. March 2018).
It occurs entirely within Kinabalu National Park.
There is a need for taxonomic research for all Philautus species occurring in Malaysian Borneo. 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 and natural history.
Red List Status
Listed as Least Concern since, although its estimated extent of occurrence (EOO) is 338 km2, it occurs in a well-protected and well-managed national park, where suitable habitat remains, and there are no threats at present.
