Wallace's large spiny rat

Wallace's large spiny rat (Halmaheramys wallacei) is a rodent found on the Obi Islands of Bisa and Obi in the Molucca archipelago of Indonesia. The Wikipedia article that serves as this entry's source explains that its genus, Halmaheramys, was first thought to hold a single species endemic to Halmahera, which gave the genus its name, so this species extends the genus to two more islands in the Maluku Archipelago. It was first found in January 1990 by the researchers T. Flannery and Boeadi, who came across a badly decomposed body on Bisa. In 2013 the authors collected three further specimens on Obi.
