Bunomys coelestis (Thomas 1896) [Mus] coelestis Thomas 1896, Ann. Mag. Nat. Hist., ser. 6, 18: 248. Type Locality: Indonesia, SW Sulawesi, Bonthain Peak (Gunung Lampobatang), 6000 ft (1830 m). Vernacular Names: Lampobatang Bunomys. Distribution: Sulawesi; endemic to the slopes of Gunung Lampobatang at tip of SW peninsula; found in montane forest formations between 1800 and 2500 m. Conservation: IUCN – Endangered. Discussion: Bunomys chrysocomus Group. More closely related to B. chrysocomus than to any other species of Bunomys. Retained as a species of Bunomys by Tate (1936), but subsequently included in a " coelestis group" of Rattus (Ellerman, 1941, 1949 a), listed as a species in subgenus Rattus (Laurie and Hill, 1954), or synonymized under Bunomys chrysocomus (Musser, 1981 c; Musser and Newcomb, 1983). Finally reinstated as a species restricted to montane forest on Gunung Lampobatang (Musser, 1991; Musser and Holden, 1991). Tate and Archbold (1935) described koka from mountains of the SE peninsula as a subspecies of B. coelestis, but that is a sample of B. chrysocomus.
