The Ilin bark rat ( Crateromys paulus ) is an extremely rare or already extinct rodent from the genus of bark climbers ( Crateromys ). It is only known from an adult male collected in 1953 on the small Philippine island of Ilin, south of Mindoro .
features
The only known specimen has a head-trunk length of 255.0 mm, a tail length of 215.0 mm, a hind foot length of 50.0 mm, an ear length of 20.0 mm and a skull length of 52.6 mm. The top is dark brown, the bottom is gray. The short, hairy, dark tail has a white tip.
habitat
The Ilin bark rat probably inhabited primary lowland rainforests. The primary forest has been cleared and only remnants of karst forest are left.
status
On April 4, 1953, Pablo Soriano collected the type specimen and sold it to Eduardo Gelena of the National Museum of Natural History in Washington, DC In 1981 it was scientifically described by Guy G. Musser and Linda K. Gordon. During an expedition in 1988, the English biologist Stuart Pritchard was unable to find any more specimens. He merely provided evidence that there was hardly any forest left on Ilin. Mindoro locals said they had a type of rat called Siyang when questioned . It is said to look similar to the Ilin bark rat, but further expeditions to Mindoro are necessary to determine the status of these animals. In 1994 the Ilin bark rat was added to the list of extinct mammals by the IUCN. In 2008 the status was changed to “insufficient data” ( data deficient ).
