Continued management of Gunung Mulu National Park is necessary for the conservation of this species (Y.M. Pui and I. Das pers. comm. March 2018).
The species is in need of close population monitoring given its restriction to a single locality. Further survey work is required in areas of suitable habitat adjacent to Gunung Mulu.
