Neill's Long-tailed Giant Rat (Leopoldamys neilli)
Size. HB:217; T: 270; HF: 42; E: 27; W: 219g
This rats upperparts are course variegated black and buffy brown. The short tail well under 290mm is dark, basally and along the top for about two thirds of its length, without vivid contrast from the white areas. There is a dusky line along the top of the foot. Juveniles are plain dark above. Mammae formula is 2+2. The skull is under 54 mm and tooth roes less than 8.9 mm.
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.
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
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.
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.
