This species is listed as Data Deficient as it is known only from the holotype which was purchased on Ilin island. However, it is unclear whether the specimen originated from there. Repeated surveys have failed to find it on Ilin island, so it could possibly be extinct. There is a possibility that it could be found on nearby Mindoro but specific surveys are required to determine this. If its presence there were to be confirmed there, the species would be likely to qualify for inclusion in a threat category.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is endemic to the Philippines, where it is known with certainty only from Ilin island. Unverified reports suggest its presence on southern Mindoro (Oliver et al. 1993). The holotype is a taxidermy mount purchased on Ilin island, but the true provenance of the specimen is unknown (L. Heaney pers. comm). However, surveys with local people have failed to reveal knowledge of the species. The specimen was "found" in the collection at the Smithsonian Museum decades after being donated (Musser and Gordon 1981).

Population [top]

Population:This species is known only from one individual. A two week survey on Ilin island and adjacent Ambulong islands in 1997 was unable to find the species; a prior survey in 1989 and a later one in 2000 were also unable to detect it and its presence has not been detected during an ongoing conservation project on Ilin island. Extensive surveys on Mindoro have failed to detect its presence. The species was reported as extinct on Ilin (Pritchard 1989).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Nothing is known about its habitat and ecology. It probably occurred in lowland forest (Musser and Gordon 1981).

Threats [top]

Major Threat(s): There is no primary forest on Ilin island, and little remains of the fragile karst forest there.

Conservation Actions [top]

Conservation Actions: There is an urgent need for surveys to determine whether the species is present on Mindoro.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
