Large New Guinea spiny rat

The large New Guinea spiny rat, Rattus praetor, is a species of rodent in the family Muridae. According to its Wikipedia article it is found in Indonesia, Papua New Guinea and the Solomon Islands, so its range crosses three countries rather than belonging to one. The article is a very short stub with no reference list of its own, and it says nothing about the animal's habitat, diet, size, behaviour or conservation. This entry therefore records only the scientific name, the family and the three countries of its range, and it leaves every other detail to later, better sourced work rather than guessing at it from the common name.
