This species is known only from south western Sulawesi, from the slopes of Gunung Lampobatang at 600-2,500 m, and also from adjacent coastal lowlands close to sea level (Musser and Carleton 2005). It may occur slightly further north on the south western peninsula in limestone formations, but this requires confirmation.
Habitat and Ecology
Habitat and Ecology
It inhabits montane and upper-montane forest, and also occurs in forest at lower elevations. It is possible that they may occur in coconut plantations, based on related species in other parts of Sulawesi

Listed as Data Deficient since the distribution limits of this species are not well known, and there is no recent information on its population status. Much of the lowland habitat in its range has been lost, but it remains unknown whether this species might occur in modified habitats, such as plantations. With further survey work, this species may warrant uplisting to a higher category of threat.
It is represented only by four modern specimens from the lowlands, and another larger series from Gunung Lampobatang. They probably still occur on the slopes of Gunung Lampobatang, although it is not known whether they might still persist in the lowlands.
The major threat is likely to be extensive habitat loss in the region, and much of the forest below 1,700 m has been completely destroyed. Above this elevation, the habitat remains in good condition, although montane forest will degrade as the result of forest loss at lower elevations. It is also, possibly affected by competition with Rattus rattus.
Gunung Lampobatang is a designated as a Protection Forest, but it is not known whether this area is well managed for biodiversity conservation. Further research is needed to determine the geographic range and population status of this species, and to establish whether it still survives in the lowlands in modified habitats.
