This species has been found at several sites within Kinabalu National Park, from 1,300–1,800 m asl, and at one site in the Crocker Range to the south, in western Sabah, Borneo. Its estimated extent of occurrence (EOO) is 1,913 km2.
Habitat and Ecology
This species lives within the leaf litter of oak-chestnut montane forests, and is known to breed in phytotelms (water-filled cavities in trees and plants such as bromeliads).
It is regarded as very common within Kinabalu and Crocker Range National Parks. The population is considered to be stable (P. Yambun pers. comm. January 2018).
There are no major threats to this species as it occurs in two well-protected and well-managed national parks (P. Yambun pers. comm. January 2018).
Both of the areas where it is known to occur lie within Kinabalu and Crocker Range National Parks.
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.
Red List Status
Near Threatened (NT)
Listed as Least Concern since, although its estimated extent of occurrence (EOO) is 1,913 km2, it occurs in two well-protected and well-managed national parks, where suitable habitat remains, and there are no threats at present.
