The species of Hapalomys (Rodentia, Muridae). American Museum novitates ; no. 2503

Abstract

"Rats of the genus Hapalomys are adapted for arboreal life and live in the forests of Southeast Asia. Current published opinions regarding taxonomy of Hapalomys claim that there is only one polytypic species in the genus, but analysis of available samples indicates there are really two distinct species: H. longicaudatus Blyth, which is monotypic, and H. delacouri Thomas, containing three subspecies. The species limits are defined on the basis of external, cranial, and dental features as well as geographic distribution"--P. [1].
