This species is known only from Mount Lompobatang in southwestern Sulawesi, Indonesia, where it is found above 1,000 m asl. Analysis of records from central Sulawesi that were previously attributed to this species and included in the previous assessment range map revealed that they belonged to Rhacophorus edentulus and have therefore been removed (A. Hamidy pers. comm. May 2017; MZB database). The extent of occurrence (EOO) of the current known range is 6,411 km2.
Habitat and Ecology
It lives in montane forest, including disturbed forest, and breeds in streams.
It is relatively common and it is frequently encountered during surveys (D. Iskandar and A. Hamidy pers. comm. May 2017). Due to ongoing decline in the quality and extent of its habitat, the population is suspected to be decreasing.
The principal threat to its habitat is encroaching smallholder farming.
The species occurs in Gunung Lompobatang Natural Reserve in which, according to regulations, the forest above 1,200 m asl should be protected (this is the case for all forest above 1,200 m asl across Indonesia); however, agriculture encroaches into the forest (D. Iskandar pers. comm. May 2017).
Ongoing and improved protection of the species habitat is required.
Further work is required to better understand the population size, distribution, and trends.
Red List Status
Near Threatened (NT)
Listed as Vulnerable because its extent of occurrence (EOO) is 6,411 km2, it is thought to occur in fewer than 10 threat-defined locations, and there is ongoing decline in the quality and extent of its habitat.
