Identities of rats from Pulau Maratua and other islands off East Borneo. American Museum novitates ; no. 2726

Abstract

"Rats from Pulau Maratua and from off the east coast of Borneo beyond the 100 fathom line were originally identified as Epimys mara and E. tua (Miller, 1913). Subsequent reports on the original series have allied the taxa with Rattus muelleri (Chasen, 1940) and house rats, R. rattus (Chasen, 1940; Medway, 1965, 1977; Schwarz and Schwarz, 1967). Actually, two species live on the island, R. rattus diardii and R. tiomanicus mara (tua is a synonym). We explain our identifications in the context of discussion and questions about R. rattus diardii and especially R. tiomanicus in the Malayan region"--P. [1].
