Family Vespertilionidae Gray, 1821

The family Vespertilionidae was the most species-rich group with six species — including two endemic subspecies — recorded from the Andaman Islands. Hesperoptenus tickelli, Tylonycteris pachypus and T. robustula are the forest-dwelling species. Tylonycteris species are bamboo-dependent and have been observed in forests with lush growth of bamboo. Pipistrellus coromandra occurs in forested tracts, while P. javanicus camortae was recorded mostly in human-dominated habitats and sometimes in the forested tracts. Myotis horsfieldii dryas was recorded only in forests and was found roosting in caves and tree hollows.
