The Great Roundleaf Bat is
amongst the largest of the Hipposideros genus, and is the largest
example in Southeast Asia. Typically the species roosts in caves, but is
also found in abandoned buildings.
Roundleaf bats are insectivorous bats characterised by a horseshoe-shaped
base to the noseleaf but, unlike the Horseshoe Bats, lack a complicated
'lancet' or projection from the top of the noseleaf.
Similar in appearance to the closely related, but smaller,
Intermediate Roundleaf Bat
Hipposideros larvatus, the Great Roundleaf Bat possesses four, not
three, lateral accessory leaflets on each side of the main noseleaf. Males
also possess a fleshy, swollen area above and behind the noseleaf.
Its thick and woolly fur is medium brown, and the ears dark brown.
The Great Roundleaf Bat ranges from parts of Eastern India, Nepal and
Southern China, through Indochina and Burma to Thailand and Peninsular
Malaysia. It is absent from Sumatra, Borneo and Java, and has not been
recorded in Singapore.
