This species is currently known only from the vicinity of Mesilau and the summit trail in Kinabalu National Park, Sabah, Malaysia, at 1,850 m asl (Inger et al. 1997, P. Yambun pers. comm January 2018). Its estimated extent of occurrence (EOO) is 264 km2.
Habitat and Ecology
This species inhabits montane forest (oak-chestnut), where specimens have been found in the leaf-litter or on rocks. Breeding presumably takes place in streams.
It is regularly found during surveys to Kinabulu National Park, however in low abundances (P. Yambun pers. comm. January 2018). The population is generally stable.
There are no major threats to the species at present as it occurs only within a relatively well-managed protected area (P. Yambun pers. comm. March 2018). The 2015 Sabah earthquake (Earth Observatory of Singapore 2017) likely had a negative impact on this species at Mesilau, although the species has since been found along the Kinabalu summit trail (P. Yambun pers. comm. March 2018).
It is known only from Kinabalu National Park, which is well protected.
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.
Red List Status
Near Threatened (NT)
Listed as Least Concern since, although its estimated extent of occurrence (EOO) is 264 km2, it occurs in a well-protected and well-managed national park, where suitable habitat remains, and there are no threats at present.
