Gressitt's mosaic-tailed rat

Gressitt's mosaic-tailed rat (Paramelomys gressitti) is a murid rodent known only from Papua New Guinea. It was described by Menzies in 1996 in a systematic revision of the New Guinea Melomys group, from a holotype collected near the summit of Mount Kaindi, at 2,300 metres in the Wau region of Morobe Province. The common name honours the collector Judson Linsley Gressitt. It belongs to the family Muridae, subfamily Murinae and the tribe Hydromyini, and lives in the Australasian biogeographic realm. Ongoing habitat degradation is described as a major threat to it, and the Mammal Diversity Database records its IUCN Red List status as Endangered.
