Abstract

Thick-thumbed bats of the genus Glischropus are currently composed of four recognized species from Southeast Asia, two of which were described in recent times. Among these species, G. aquilus is endemic to Sumatra, G. javanus is restricted to western Java, whereas G. bucephalus is widely distributed north to the Isthmus of Kra and G. tylopus is widespread south to this zoogeographic boundary. Two recently collected Glischropus specimens from Meghalaya state in north-eastern India extend the known distribution range of the genus westward into South Asia by ca. 1000 km. Morphological examination of these specimens and comparison with all known species in this genus revealed marked differences in colouration, dental characters and bacular traits. We therefore describe the Meghalaya specimens as a new species. The discovery of the new species from a forest patch adjacent to Nongkhyllem Wildlife Sanctuary from where another specialized bamboo-dwelling species (Eudiscopus denticulus) was reported recently also underscore the importance of the area from a conservation point of view.
