The white-tailed rat also known as the white-tailed mouse, is the only member of the subfamily Mystromyinae in the family Nesomyidae. This species is sometimes placed in the subfamily Cricetinae due to similarities in appearance between the white-tailed rat and hamsters, but molecular phylogenetic studies have confirmed that the two groups are not closely related. The subfamily Mystromyinae is sometimes placed within the family Muridae along with all other subfamilies of muroids.
The Andean rat, or white-tailed akodont, is the only species in the genus Lenoxus. It is a rodent in the tribe Akodontini found on the eastern slopes of the Andes of eastern Peru and western Bolivia. Examination of its genome shows that this species is not closely related to Oxymycterus as had previously been thought, but is quite distinct, having diverged from the other Akodontini soon after the basal radiation of the entire group.
The Ethiopian forest brush-furred rat or golden-footed brush-furred rat, is a species of rodent in the family Muridae. It is endemic to Ethiopia where its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Melomys is a genus of rodents in the family Muridae. Members of this genus live in the wet habitats of northern Australia, New Guinea, Torres Strait Islands and islands of the Indonesian archipelago.
The Manusela mosaic-tailed rat is a species of rodent in the family Muridae. It is found only in Indonesia. It lives in the rainforests on the island of Seram in Indonesia. Specimens of it weigh 66.5g and have a head and body length of 118-135mm and a tail length of 126–140mm.
The white-bellied mosaic-tailed rat is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea.
The Bramble Cay melomys, or Bramble Cay mosaic-tailed rat, is a recently extinct species of rodent in the family Muridae and subfamily Murinae. It was an endemic species of the isolated Bramble Cay, a vegetated coral cay located at the northern tip of the Great Barrier Reef in Australia. Described by researchers as having last been seen in 2009 and declared extinct by the Queensland Government and University of Queensland researchers in 2016, it was formally declared extinct by the International Union for Conservation of Nature (IUCN) in May 2015 and the Australian government in February 2019. Having been the only mammal endemic to the reef, its extinction was described as the first extinction of a mammal species due to anthropogenic climate change.
The Nillu rat or Sri Lankan mountain rat is a species of rodent in the family Muridae. It is found only in Sri Lanka where it is known as நில்ளு எலி in Tamil and නෙලූ මීයා(Nelu Meeya) in Sinhalese.
The Malayan field rat, Malaysian field rat or Malaysian wood rat, is a species of rodent in the family Muridae. It is nocturnal and mainly arboreal and is found in Malaysia, Thailand, Indonesia and the Philippines. It is a common species and the International Union for Conservation of Nature has assessed it as being of "least concern".
The Florida naked-tailed rat is a poorly known and possible extinct species of rodent in the family Muridae. It was confined to the Nggela Islands in the Solomon Islands. The originally mentioned type locality Ugi Island is an erratum.
Boehm's gerbil is a species of rodent found in Angola, Burundi, Democratic Republic of the Congo, Kenya, Malawi, Mozambique, Rwanda, Tanzania, Uganda, and Zambia. Its natural habitats are dry savanna, moist savanna, and arable land. This is a common species with a wide distribution which faces no obvious threats, so in 2004 the International Union for Conservation of Nature rated its conservation status as being of "least concern".
The Banda Sea Islands moist deciduous forests is a tropical moist forest ecoregion in Indonesia. The ecoregion includes several island groups in the southwestern Banda Sea, including the Tanimbar Islands, Kai Islands, and the Barat Daya Islands except for Wetar.
Daniel's tufted-tailed rat is a species of rodent in the family Nesomyidae. It was discovered in 2003 in the Parc National de l’Isalo in south-central Madagascar. It is named for Daniel Rakotondravony, professor of animal biology at the University of Antananarivo, Madagascar.
The long-nosed paramelomys is a species of rodent of the family Muridae endemic to New Guinea. It is found in the lowlands of the south of the country.
The Rossel Island melomys is a species of rodent from the family Muridae. It is endemic to Rossel Island in Papua New Guinea, but Flannery (1955) presumed that "it did exist previously on other islands of the group, but has become extinct on all except Rossel." For many years it was seen as a subspecies of the white-bellied mosaic-tailed rat, but is now considered a distinct species. It is listed as data deficient by the IUCN Red List in light of little information on "population status, ecological requirements, and threats". The Rossel Island melomys has not been officially recorded since 1956, but its habitat is still in good condition. The IUCN lists determining population status of the melomys as a "high priority".
The Pavel's Seram mosaic-tailed rat is a species of rodent in the family Muridae. It is found only on the south coast of the island of Seram in Indonesia. At one time it was thought to be a subspecies of the black-tailed mosaic-tailed rat but in 2005, Musser and Carleton raised it to full species level. The IUCN has insufficient information on which to assess its conservation status so it is listed as "data deficient".
The short-tailed Talaud mosaic-tailed rat or the short-tailed Talaud melomys is a species of rodent in the family Muridae. It is endemic to Karakelong and Salebabu in the Talaud Islands in Indonesia where it occurs in forest habitats. The long-tailed Talaud mosaic-tailed rat is also present on the islands and the shorter tail of this species means that it is likely to be mainly terrestrial whereas M. talaudium is largely arboreal.
The long-tailed Talaud mosaic-tailed rat or the long-tailed Talaud melomys is a species of rodent in the family Muridae. It is endemic to Karakelong and Salebabu in the Talaud Islands in Indonesia where it occurs in forest habitats. It is morphologically similar to the white-bellied mosaic-tailed rat and was at one time considered to be a subspecies but is now recognised as a distinct species. The short-tailed mosaic-tailed rat is also present on the islands and the shorter tail of that species means that it is likely to be mainly terrestrial whereas M. talaudium is largely arboreal.
The Seram long-tailed mosaic-tailed rat, also known as the Seram long-tailed melomys, is a species of rodent in the family Muridae. It is found only on the south coast of the island of Seram in Indonesia. At one time it was thought to be a subspecies of the white-bellied mosaic-tailed rat but was subsequently raised to full species level. It differs from that species in having a much longer, scale-free tail with a calloused tip which is likely to be prehensile and used while climbing trees.
The Riama mosaic-tailed rat, is a species of rodent in the family Muridae. It is found only on the island of Riama in Indonesia, a small island to the west of Selaru in the Tanimbar Islands. Very little is known about this species, but it may also be present on some of the other islands in this group.
