Marmoset Rat (Hapalomys longicaudatus)

 

Description

Size. HB: 155-168;T: 179; HF: 28; E: 13.

A chubby, blunt nosed rat with tufts of long whiskers, extending from the ear and face. The fur is soft and  brown. The molars have even rows of cusps in a checkerboard pattern of threes both crosswise and lengthwise.. Otherwise the rat and its skull look like a larger edition of Chiropodomys. The mammae are 2+2.

Range Description:

The species has a patchy distribution, it has been recorded from Myanmar and Western Thailand, however, it may be extirpated from these countries as little natural vegetation remains. An extant population occurs in Peninsular Malaysia (Musser and Carleton 2005). Specimens of H. longicaudatus reported from Yunnan by Wang (2003) probably represent H. delacouri.
Countries: Native:
Malaysia
Possibly extinct:
Myanmar; Thailand

Population:

It was formerly recorded as being common in Myanmar and Thailand ,but all of the natural habitat within the known range has now been cleared.
Population Trend: Decreasing

Habitat and Ecology:

This species is known only from natural stands of bamboo in evergreen lowland rainforest. It is a lowland species in the northern part of its range; it is recorded from around 500 m in Malaysia. The diet of this species is restricted to various parts of bamboo.
Systems: Terrestrial

Major Threat(s):

This species appears to be associated with natural stands of bamboo, a habitat of which very little remains within the known range of the species (D. Lunde and K. Aplin . Remaining stands of this bamboo are being cut for building materials and other uses. It is possibly extirpated in Myanmar and Thailand.

Conservation Actions:

It is present in the Cameron Highlands (Malaysia) and is likely to be present in the Cameron Highlands Wildlife Sanctuary, however, this needs to be confirmed. There is a need to protect remaining stands of natural undisturbed bamboo where the species has been recorded, and to conduct additional surveys to locate any additional remaining populations in habitat patches.
