Large-thumbed bats ( Glischropus ) are a species of bat from the family smooth-nosed bats (Vespertilionidae). There are four species found in Southeast Asia.
- Glischropus aquilus occurs on Sumatra, has a dark brown fur and almost black ears.
- Glischropus bucephalus from Indochina.
- Glischropus javanus is endemic to Java .
- The distribution area of Glischropus tylopus extends from Myanmar , Laos and Vietnam over the Malay Peninsula , Sumatra and Borneo to the western Philippines . A small population occurs in the Bacan Islands .
The species are small members of the family with a head-to-trunk length of around 40 mm, a forearm length of 28 to 35 mm and a weight of 3.5 to 4.5 g. The tail is 32 to 40 mm long. The upper side of the fur is red-brown to black in color, the underside is usually lighter. The name-giving feature are the thick pads on the thumbs and feet, which are more pronounced than those of the pipistrelle bats ( Pipistrellus ). Compared to the bamboo bats ( Tylonycteris ), the tragus on the ear is longer and more pointed.
The way of life of the big-thumb bats is strongly linked to bamboo . They usually rest in hollowed-out bamboo stalks. Other resting places are crevices and banana leaves. These bats eat insects.
The World Conservation Union (IUCN) lists Glischropus tylopus as Least Concern and Glischropus javanus with a lack of data ( Data Deficient ).
