This species is only known from Mount Lompobatang and Mount Latimojong, in southwestern Sulawesi, Indonesia, above 1,200 m asl. Its extent of occurrence (EOO) is 10,630 km2 and all individuals are considered at five or fewer threat-defined locations.
Habitat and Ecology
This species lives in undisturbed highland forest, usually close to small rivers and streams. The eggs are laid in a burrow on the river bank, where they are guarded by the male. The larvae hatch on land and slide and tumble downhill into slow- to medium-flowing streams, where they develop further.
It is an uncommon species. Surveys in 2013 recorded the species, however it is difficult to locate (D. Iskandar pers. comm. May 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The main threat is forest clearance for smallholder farming and expanding human settlements, which has resulted in extensive forest loss on mountain slopes within its range. This species is also threatened by the drying up of streams on which it depends.
This species is found in the Gunung Latimojong Nature Reserve and Gunung Lompobatang Protected Forest.
There is a need for improved habitat protection throughout its range.
Further research on this species' distribution, population size and trends, and threats is recommended.
Red List Status
Listed as Vulnerable because its extent of occurrence (EOO) is 10,630 km2, it occurs in five or fewer threat-defined locations, and there is ongoing decline in the extent and quality of habitat on Sulawesi for smallholder farming and expanding human settlements.
