The southeastern xanthurus rat (Rattus salocco), is a rodent of the genus Rattus.
This species is known only from the southeastern peninsula of Sulawesi, where it has been found at 300 and 1,500 m (980 and 4,920 ft) altitude.[2] Only three specimens of this poorly understood species are known; the last were collected in 1932 at the mountain Tanke Salokko. The IUCN Red List therefore lists the species as Data Deficient.[3]
Although R. salocco is usually considered a subspecies or synonym of Rattus xanthurus, R. salocco was recognized as a separate species more closely related to R. marmosurus in the 2005 third edition of Mammal Species of the World.[2]
