U. S. Natl. Mus ., 24: 759 . Type Locality: India , Andaman Isls, Henry Lawrence Isl. Vernacular Names: Andaman Archipelago Rat . Synonyms: Rattus rogersi (Thomas 1907) ; Rattus taciturnus ( Miller 1902 ) . Distribution: Islands of Henry Lawrence, Little Andaman, and South Andaman in the Andaman Arch. ( Musser and Newcomb, 1983 ). Conservation: IUCN – Vulnerable. Discussion: Rattus rattus species group. Despite past confusion with Sundamys muelleri , R. stoicus is defined by a unique set of derived and primitive features and is endemic to the Andaman Isls (Musser and Heaney, 1985; Musser and Newcomb, 1983 ). Its closest phylogenetic ally within the R. rattus species complex has yet to be determined (Musser, 1986).
