Large mosaic-tailed rat

The large mosaic-tailed rat (Mammelomys rattoides) is a species of rodent in the family Muridae. It is found in West Papua in Indonesia and across the border in Papua New Guinea, on the island of New Guinea. The Mammal Diversity Database lists it in the Australasian realm and records the other common names lowland mammelomys, large melomys and large-scaled melomys. It was described by O. Thomas in 1922 in a paper on new mammals from New Guinea and neighbouring islands, from a specimen collected at a camp called Pionier-bivak on the Mamberamo River at about 61 metres above sea level. The IUCN Red List status recorded by the database is Least Concern.
