TYPE LOCALITY: E Kenya , Lake Naivasha . DISTRIBUTION: Known only by specimens from E Kenya , and N and E Tanzania ; limits unknown. COMMENTS: Originally described as a species of Thamnomys ( Heller, 1909 ) , then listed as a subspecies of Thallomys nigricauda ( Allen, 1939 ; Ellerman, 1941 ), and finally allocated to T. damarensis (here included in nigricauda ) as a subspecies ( Petter, 1973a ). T. loringi is morphologically and probably phylogenetically allied to T. nigricauda , but no critical documentation of its conspecificity with that species has ever been presented. Because T. loringi can be diagnosed by pelage and other distinctions, we list it as a species, a hypothesis that can be tested by careful systematic revision of the genus.
