Saxatilomys paulinae, Paulina's limestone rat, is a species of murid rodent native to central Laos and Vietnam, separated to a monotypic genus Saxatilomys. It was first discovered in the Khammouan Limestone National Biodiversity Conservation Area in Khammouan Province, Laos, and also been found in the Vietnamese province of Quang Bình. [2] It is the only known species in the genus Saxatilomys. [3] The genus name is derived from the Latin saxatilis, meaning "among the rocks" and the Greek mys, meaning mouse or rat. [3]

Description

It resembles, and is likely closely related to, species in the genera Niviventer and Chiromyscus . Saxatilomys is distinguished from these and other Indomalayan genera by "semispinous dark gray upperparts, dark frosted gray underparts, large, extremely bulbous footpads, and a combination of derived and primitive cranial and dental traits". [3]

Habitat

It is thought to be petricolous and has only been observed in forested, rocky limestone habitats. [3]
