discussion
Discussion: Rattus rattus species group. Morphological, chromosomal, distributional, and ecological boundaries of species elaborated by Musser and Holden (1991), who also documented taxonomic history. Stomach morphology described and contrasted with other Sulawesian endemics by Musser and Durden (2002). Closest relative of R. hoffmanni is R. mollicomulus from Gunung Lampobatang, Sulawesi. Rattus koopmani, endemic to Pulau Peleng, is also likely closely related to R. hoffmanni. Phylogenetic affinities of this cluster to other species of Rattus are unresolved.
Order Rodentia - Family Muridae
distribution
Distribution: Sulawesi; throughout island except upper slopes of Gunung Lampobatang at the end of the SW peninsula; also on Pulau Malenge in Kepulauan Togian (Musser and Holden, 1991).

COMMENTS: Morphological, chromosomal, distributional, and ecological boundaries of species elaborated by Musser and Holden (1991), who also documented taxonomic history. Closest relative of R. hoffmanni is R. mollicomulus from Gunung Lampobatang, Sulawesi; both form the monophyletic Rattus hoffmanni group. Phylogenetic affinities of this group to other species of Rattus is unresolved.
