HB: 177; T:168; HF: 37; E: 21; W: 122g
A medium sized, brown greyish rat with a dark tail, dull grey underparts and pearly white feet.; mammae 3+3, sort short fur, long rostrum, and broad, flat cranial roof. There are 8 pairs of small metacentric chromosomes. No ectoparasites have been found.
This very widespread Asian species, ranges from North-Eastern
South Asia (Bhutan, India and Nepal [Molur et al. 2005]; probably present in
Bangladesh), much of Central, Southern and Eastern China (including the island
of Hainan) (Smith and Xie 2008), ranging into Southeast Asia, where it has been
recorded from Myanmar, Thailand, Lao PDR, Vietnam and probably occurs
more widely. It has been introduced to Benguet Province, Luzon in the
Philippines; Palau; central Sulawesi (Indonesia); Seram (Indonesia); and the
Vogelkop Peninsula of Papua Province (Indonesia) (Corbet and Hill 1992; Flannery
1995; Musser and Carleton 2005). In South Asia the species occurs from 686 to
2,740 m asl (Molur et al. 2005). It is presumably found as low as sea level in
parts of its range.
