Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Endangered because its extent of occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat. A survey by the National Museum of Indonesia in 1991 failed to detect the species. It should possibly be included in the Critically Endangered category (with the possibly Extinct box checked) once the status is better determined.
