This species is known only from northeastern Sulawesi, Indonesia, above 1,000 m asl. The extent of occurrence (EOO) of its known range is 19,196 km2.
Habitat and Ecology
This species occurs in montane forest, and presumably lays eggs on the ground that develop directly without a larval stage.
The current population status of this species is unknown. Until it was rediscovered in 1999, it was known only from the holotype. An additional record has been confirmed from surveys in 2004 on Mount Klabat, but no surveys have taken place at this same site since (D. Iskandar unpubl. data in the MZB collection).
The area where it occurs is experiencing some of the most severe habitat loss in Sulawesi, with forest clearance for cacao and clove plantations and wood collection having taken place almost up to the mountain summits. In addition, the mountains on which the species occurs are active volcanoes and the potential risk of explosions represent a threat to the species.
This species probably occurs in the Bogani-Nani Wartabone National Park and the Tangkoko-Batu Angus and the Dua Sudara Nature Reserves. However, these two nature reserves have been very heavily deforested.
There is a need for much strengthened management, including habitat restoration, of existing protected areas in this region.
Further survey work to better understand the population size, distribution, and trends.
Red List Status
Listed as Vulnerable because its extent of occurrence (EOO) is 19,196 km2, it occurs in fewer than 10 threat-defined locations, and there is ongoing decline in the extent and quality of its habitat.
