A new genus of arboreal rat from Luzon Island in the Philippines. American Museum novitates ; no. 2730

Abstract

"The taxon latidens Sanborn, 1952, originally named and described as a species of Rattus, is taken out of that genus and placed in Abditomys, new genus. Some of its distinctive features, such as nails instead of claws on the halluces, wide upper incisors, and large molars with simple and laminar-like occlusal surfaces are not characteristic of Rattus. The species is known by two specimens from the island of Luzon in the Philippines. The relationship of latidens to other Murinae with nails on the halluces is discussed. Aspects of its natural history are presented"--P. [1].
