Range Description:

The species has been recorded from a few locations in limestone areas of Northern and South Western Thailand, north of the peninsular region. The range may extend into adjacent areas of Myanmar and Vietnam, however, these populations might represent a separate species (Musser and Carleton 2005). It has a rough elevational range of 100 to 800 m.
Countries: Native:


The population abundance is not well known. According to Wiles (1981) this species is rare in lowland bamboo forest in Salak Phra Wildlife Sanctuary in South Western Thailand.
Population Trend: Unknown

Habitat and Ecology:

Very little is known about this species of rat and  of the few specimens collected, some have been taken from wooded limestone cliffs and others from lowland bamboo forest (Musser and Carleton 2005).
Systems: Terrestrial

Major Threat(s):

There are possibly no major threats to the limestone areas where this species is found. There may be some trapping, but probably not a level that would threaten the species.

 Conservation Actions:

 It is present in Salak Phra Wildlife Sanctuary and may be present in Phu Hin Rong Kla National Park. Further studies are needed into the taxonomy, distribution, abundance, ecology, and threats to this poorly-known species.
