Taxonomy & Nomenclature



Conservation Status

Last record: 4 April 1953

IUCN RedList status: Data Deficient


Only known from the holotype, most likely endemic to Ilin Island in the Philippines as it was bought there. But as it was not observed in the wild and is only known from the holotype, which is of unknown provenance, it may possibly inhabit nearby Minodoro Island.

Subfossil remains of this species have since been found on Illin Island, thus confirming it's former existence there (Reyes et al. 2017).



Ilin Island, Philippines






Holotype: USNM 522023
