Eastern small-toothed rat

The eastern small-toothed rat, Macruromys major, is a rodent in the family Muridae. Wikipedia records it from West Papua in Indonesia and from Papua New Guinea, which together cover the island of New Guinea. It was named in 1935 in a paper on new murids from New Guinea, and the Mammal Diversity Database gives its type locality as the Kratke Mountains in the Eastern Highlands Province of Papua New Guinea, at about 1,220 to 1,524 metres. That database lists it as a living species of the Australasian realm, in the subfamily Murinae and the tribe Hydromyini, with a Least Concern rating on the IUCN Red List. It also records the alternative common names Greater Small-toothed Rat and Greater Macruromys, which set it against Macruromys elegans, the Lesser Small-toothed Rat, the only other species of the genus in the database. The Animal Diversity Web places the genus Macruromys among the New Guinean rats and small-toothed rats.
