Mount Dulit, c. 700 m [2000 feet], north Borneo.
Closely related to the more widespread, lowland B. auritus; both occur at Mt Dulit, with B. auritus recorded only at lower elevations; reports of specimens intermediate between the two are apparently erroneous. Monotypic.
Mountains of N & C Borneo: known from Mt Dulit, Usun Apau Plateau, Kelabit Uplands (all in Sarawak) and Mt Liang Kubung (NE West Kalimantan).
