The western New Guinea mountain rat (Rattus arrogans) is a species of rodent in the family Muridae. [2] It is widespread in the mountains of central and western New Guinea.
Rattus is a genus of muroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus.
The summit rat is a species of rodent in the family Muridae. It is found only on Mount Kinabalu and Mount Tambuyukon, Malaysia, and has been recorded at altitudes of 2,040 to 2,477 m on Mt. Tambuyukon and 2,670 to 3,426 m on Mt. Kinabalu. They are most abundant in higher altitude dwarf forest and montane scrubland. The rat populations from these two peaks were connected in the Holocene. However, nowadays they are genetically isolated despite they are only 18 km apart. With current predictions of Global warming, the suitable habitat for Rattus baluensis is expected to shift around 500 m upwards. This will put the population in Mount Tambuyukon at risk. However, the population in Mount Kinabalu will likely survive in its upper slopes. Genetic analysis situate its origin in a local population of Rattus tiomanicus from northern Borneo at around 300-400 thousand years ago.
The Philippine forest rat is a species of rodent in the family Muridae. It is found only in the Philippines, and is located throughout the archipelago. The scientific name commemorates British colonial administrator and zoological collector Alfred Hart Everett. The Chanum Torres is widespread throughout its range and feeds on a diet of worms and insects. There are no major threats to the species, which has been found to be competitively superior to introduced Rattus species.
The Giluwe rat is a species of rodent in the family Muridae. It is found only in Papua New Guinea, on Mount Giluwe and the subalpine grasslands of the Kaijende Highlands.
Hoogerwerf's rat is a species of rodent in the family Muridae. It is named after zoologist Andries Hoogerwerf and is found only in western Sumatra, Indonesia, including Mount Leuser, where it is found only above 2000 m. It is known from few museum specimens. Genetic analysis indicate its closest relative is Rattus korinchi, another Sumatran mountain rat from which it diverged around 1.4 million years ago.
Korinch's rat is a species of rodent in the family Muridae. It is found only in western Sumatra, Indonesia, and is only known from Mount Kerinci and Mount Talakmau, where it is endemic to high elevations above 2000 m. It is only known from two museum specimens collected early in the 20th century. Genetic analysis indicate its closest relative is, another Sumatran mountain rat from which it diverged around 1.4 million years ago.

The dusky field rat, also known as the canefield rat, is a species of rodent in the family Muridae. It is found in Australia, Indonesia, and Papua New Guinea. In Australia it is found in northern Queensland and along the east coast as far south as Shoalwater Bay, where it is plentiful, and on South West Island in the Sir Edward Pellew Group off the Northern Territory, where it is considered a threatened species.
