Sundaic Rattus : definitions of Rattus baluensis and Rattus korinchi. American Museum novitates ; no. 2862

Abstract

"Among the 14 genera and 41 species of murid rodents that are native to the peninsula and islands on the Sunda Shelf are five species of Rattus. Two of these, R. baluensis from Gunung Kinabalu in Sabah and R. korinchi from the mountains of central Sumatra, were regarded as isolated mountain populations of one species. Restudy of specimens in museum collections indicates the Bornean population to be a species closely related to the widespread Sundaic R. tiomanicus, which is a relative of R. rattus and other species native to continental Asia and India. Morphological characteristics of R. korinchi are unlike any other species of Rattus. These endemic Bornean and Sumatran Rattus are contrasted and defined"--P. [1].
