[3][4] 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.

[1][6] The specific epithet darjelingensis references the Indian town of Darjeeling, the type locality of this species.

Its range is thought to comprise mountainous areas at moderate elevations, where it inhabits montane temperate and subtropical forests.

[1] Populations in South Asia are threatened by deforestation, which has reduced the range and quality of potential habitat for this species.
