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.
