Nycteris tragata,
or Malayan Slit-faced Bat, (also called Hollow-faced Bat), inhabits lowland
primary forest, hill and montane forest, and peat swamp forest. Known roosts
include hollowed-out fallen trees, rock crevices, caves and man-made
culverts. Roosts typically comprise small groups.
The diet of this medium-sized bat comprises large insects, such as moths and
crickets: rather than catch insects on the wing, it plucks or 'gleans' them
from surfaces including the ground. It probably locates such prey by
passively listening for faint noises.
Its fur is rich brown to light brown, with paler bases, and is long and
woolly in texture.
Its ears are long, rounded and
forward facing. Its simple 'noseleaf' comprises parallel skin flaps on
either side of a depressed groove that extends from the nose to between the eyes.
Its tail is long with a 'T' or 'Y' shaped tip, and this is fully enclosed in
the interfemoral membrane that stretches between its two legs. Its wings are
broad and relatively short.
This species occurs in southern Myanmar, southern Thailand, Peninsular Malaysia, Singapore
(where it is extremely rare), Borneo and Sumatra.
One other closely-related species of slit-faced bat occurs in Southeast
Asia, namely Nycteris javanica, which occurs in Java and the Kangean
Islands of Indonesia. At least 10 other
Nycteris species occur in Africa.
