Of these, 19 middle-sized to large species belong to genera formerly grouped within the single genus Rattus by regional systematists including Chasen (1940), and Ellerman & Morrison-Scott (1951). Now divided among six genera, Lenothrix, Leopoldamys, Sundamys, Maxomys, Rattus and Niviventer (Wilson & Reeder, 2005), these species (Table 1) are collectively regarded as ‘rats’ for present purposes: tikus in Bahasa Malaysia.application/pdfen-AU@ 201520152020-12-20
