Papagomys is a genus of very large rats in the tribe Rattini of the subfamily Murinae, with body masses of 600–2,500 grams (1.3–5.5 lb).[1] It contains two species, which are known only from the Indonesian island of Flores:[2]
Verhoeven's giant ratPapagomys theodorverhoeveni (possibly extinct, only known from subfossil remains)
A possible unnamed third species is also known from subfossil remains.[1]
Both species have records extending to the early Late Pleistocene.[3] The species are thought to be terrestrial, preferring closed habitats, with P. armandvillei known to engage in burrowing. They are thought to be omnivores, consuming leaves, fruit and invertebrates.[1]
It is interesting that in 2009 in Papua New Guinea, a huge species of rat was discovered in an isolated volcanic crater (Bosavi woolly rat).[4]
