Order : CHIROPTERA
Family : Hipposideridae
Species : Hipposideros larvatus

Forearm Length : up to 6.5cm
Weight : up to 10 grams

This species roosts in caves, abandoned mines and rock crevices, sometimes in large numbers. It is similar to, though smaller than, the Great Roundleaf Bat Hipposideros armiger.

The diagnostic feature of the Intermediate Roundleaf Bat is the three lateral accessory leaflets on each side of the noseleaf (see fig 3).

The fur colour is dark grey-brown or reddish brown, and the ears and noseleaf dark grey or brown. The ears are broad and roughly triangular in shape.

The species is widely distributed from southern China through Burma, Thailand and Indochina to Malaysia, Sumatra,  Borneo and Java. It has not been recorded in Singapore.
