Rattus hainaldi Kitchener, How, and Maharadatunkamsi 1991 Rattus hainaldi Kitchener, How, and Maharadatunkamsi 1991, Rec. West. Aust. Mus., 15: 557. Type Locality: Indonesia, Nusa Tenggara, Pulau Flores, Gunung Ranakah, 1300 m, above Kampong Robo, Desa Longko, 8 km SSE Ruteng. Vernacular Names: Hainald's Flores Island Rat. Distribution: Known only from Flores Isl. Conservation: IUCN – Lower Risk (nt). Discussion: Rattus species group unresolved. Described from two specimens (Kitchener et al., 1991 c), and later found to be common in forest habitats (Kitchener and Yani, 1998; Kitchener et al., 1998). Phylogenetic affinities uncertain; placement in Rattus originally provisional (Kitchener et al., 1991), results from albumin immunology suggest transfer to either Bunomys or Komodomys (Watts and Baverstock, 1994 b), but electrophoretic data indicate R. hainaldi to be equidistant from the Komodomys-Rattus timorensis clade of Nusa Tenggara clade and true Rattus (K. Aplin, in litt., 2004).
