This species is known only from Mounts Lompobatang and Latimojong, above 1,000 m asl in southern Sulawesi, and from Gunung Karua at 1,200 m asl in south-central Sulawesi, Indonesia. The extent of occurrence (EOO) of its currently mapped range is 17,791 km2.
Habitat and Ecology
It lives in undisturbed highland forested areas. It presumably lays eggs on the ground and breeds by direct development without a larval stage.
It appears to be an uncommon, and patchily distributed, species. Due to the ongoing decline in the quality and extent of its habitat, the population is suspected to be decreasing.
The primary threat is habitat destruction and conversion due to expanding human settlements, smallholder farming and wood collection.
It occurs in the Gunung Lompobatang and Latimojong Nature Reserves.
Ongoing and improved habitat protection is required both inside and outside of the protected areas in which it occurs.
Further work is required to better understand the population size, distribution, and trends.
Red List Status
Listed as Vulnerable, because its extent of occurrence (EOO) is less than 17,791 km2, it occurs in fewer than 10 threat-defined locations, and there is a continuing decline in the extent and quality of its forest habitat on Sulawesi.
