Great Key Island giant rat

The Great Key Island giant rat (Uromys siebersi), also called the Great Key Island uromys, is a rodent in the family Muridae that is known only from Great Key Island in Indonesia. Its species name honours the ornithologist H. C. Siebers. The Mammal Diversity Database credits the species to O. Thomas, who described it in 1923 in a paper titled A new Uromys from the Kei Islands, and gives the type locality as Gunung Daab on Pulau Kai Besar, which is Great Key Island, in Maluku Tengah. It places the species in the genus Uromys within the tribe Hydromyini, assigns it to the Australasian biogeographic realm and lists its IUCN Red List status as Not Evaluated.
