It was described by
Brian Houghton Hodgson in 1855, and was previously thought to be a subspecies of the
Arabian barbastelle (
B. leucomelas), with
B. leucomelas being previously known as the eastern or Asian barbastelle when it contained
B. darjelingensis. However, a 2008 study, and several later genetic analyses, found
B. leucomelas to be a distinct species from
B. darjelingensis, and thus split them both. The
American Society of Mammalogists,
IUCN Red List, and
ITIS all follow the results of this study. Further genetic studies indicate that
B. darjelingensis itself contains many cryptic lineages that could represent distinct species, but this is disputed due to all most populations having similar morphology to one another. However, the
Caspian barbastelle (
B. caspica) and
Japanese barbastelle (
B. pacifica) are indeed thought to represent distinct species and have been split as such by the ASM and ITIS, with the IUCN also acknowledging them but not yet providing a conservation status. The
specific epithet darjelingensis references the
Indian town of
Darjeeling, the
type locality of this species. == Distribution and habitat ==
