Arianus's rat

Arianus's rat (Rattus omichlodes), also known as Arianus' New Guinea mountain rat, is a species of rat native to the mountains of Papua Province, Indonesia, according to the Wikipedia article that serves as this entry's source. The article is a single sentence, so it gives no family, body measurements, habitat description, diet, lifespan, population figure or conservation category. Those details are left blank here rather than guessed. What the source does establish is the animal's scientific name in the genus Rattus, its alternative common name, and its montane range in the Indonesian part of New Guinea.
