Abstract
Within the tribe Pipistrellini, the genus Glischropus is very close to the genus Pipistrellus both in its external morphology and chromosomal features but can be unequivocally distinguished from the latter by the presence of thumb pads and the position of the second incisor. One of the two known species, G. tylopus was thought to have a wide distribution range from Myanmar to the Philippines, while the other, G. javanus is only known from Java. Recently collected Cambodian specimens of Glischropus are distinguished from their congeners by longer forearm and cranial features (the shape of the skull and the upper incisors and certain craniodental measurements) and are consequentially, described here as a new species. Based on thorough examination of the available museum material, it can be concluded that all specimens of G. tylopus previously collected in the Indochinese zoogeographic subregion are in fact representatives of this new species, while G. tylopus in a strict sense is restricted in the mainland to south of the Isthmus of Kra.
