Several species of rodent have been newly identified in different parts of the world since 2000.

Scientific name Common name Year identified Location Notes
Baletemys kampalili Kampalili shrew-mouse 2022 Philippines It is the only species in the genus Baletemys. It is found only on Mount Kampalili, in the highlands of Eastern Mindanao, in the Philippines.
Thomasomys burneoi Burneo's Oldfield mouse 2022 Ecuador [1][2]
Mallomys? sp. Bosavi woolly rat 2009 Papua New Guinea A new species of giant rat, believed to belong to the genus Mallomys.[3]
Leptomys paulus
Leptomys arfakensis 		2008 New Guinea These two new species belong to the endemic New Guinea rodent genus Leptomys (Murinae). L. paulus is indigenous to the montane forests in the Owen Stanley Range in eastern New Guinea. L. arfakensis is known only from the Arfak Mountains on the Vogelkop Peninsula in western New Guinea.[4]
Eliurus danieli 2007 Madagascar A new species was described from the Parc National de l’Isalo in south-central Madagascar.[5]
Isothrix barbarabrownae 2006 Peru A new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabits Andean cloud-forests at 1,900 m (6,200 ft) in Peru’s Manu National Park and Biosphere Reserve.[6]
Tonkinomys daovantieni 2006 Vietnam T. daovantieni is a new species within a new genus of murid rodent. It was described from talus habitats in the forested tower karst landscape of the Huu Lien Nature Reserve of northeastern Vietnam.[7]
Mus cypriacus 2006 Cyprus
Rhynchomys sp. 2005/6 Philippines A new species of tweezer-beaked rodent was discovered on a mountain in the northern Philippines in 2005, belonging to the genus Rhynchomys. The grey rodent was found atop Mount Tapulao, northwest of Manila, and was expected to be formally named in 2006.[8]
Apomys camiguinensis
Bullimus gamay 		2006
2002 		Philippines The island of Camiguin in the Philippines is home to two recently discovered mammal species that are found nowhere else in the world. A. camiguinensis is a type of wood mouse with two sets of whiskers. Another new species of mouse, B. gamay, was discovered on the island in 2002. Along with a parrot and a frog, Camiguin has four known endemic species, which is remarkable for an island only 229.8 km2 (88.7 sq mi).[9]
Laonastes aenigmamus Laotian rock rat 2005 Laos The Laotian rock rat or kha-nyou, named in 2005 after being discovered for sale as meat on a market in Laos in 1996. This dramatic new rodent was placed in the new genus Laonastes, and was originally placed in a new family Laonastidae. It has since been placed in the ancient family Diatomyidae, making the kha-nyou a "living fossil".[10]
Akodon philipmyersi 2005 Argentina A. philipmyersi is a new species of grass mouse from Argentina.
Reithrodontomys bakeri Guerrero harvest mouse 2004 Mexico A new species of Cricetidae was discovered in the mountains of Guerrero, Mexico. It was named honoring Dr. Robert Baker. It is known only from the type locality.[11]
Oryzomys andersoni Anderson's rice rat 2004 Bolivia A new species of rice rat was discovered in Bolivia.[12]
Peromyscus schmidlyi 2004 Mexico P. schmidlyi is a species of deer mouse from Durango, Mexico. It had long been suspected as a unique species, and this was confirmed in 2004.
Rhagomys longilingua Peruvian arboreal mouse 2003 Peru A new species of Cricetidae – the Peruvian arboreal mouse, or woodpecker mouse – was discovered in Peru. It is unusual in having a long tongue, which it uses to find insects in tree bark, very much like a woodpecker.[13] Its closest relative, the Brazilian Arboreal Mouse (R. rufescens) is one of the world's rarest mammals, with only a handful of specimens ever found.
Microtus bavaricus Bavarian pine vole 2000 Germany The Bavarian pine vole was rediscovered when it was caught in a "living trap" in Germany in 2000. The vole had not been sighted since 1962, and had been declared extinct.[14]
Pipanacoctomys aureus
Salinoctomys loschalchalerosorum 		Golden vischacha rat
Los Chalchaleros viscacha rat 		2000 Argentina Two new genera of family Octodontidae – Pipanacoctomys and Salinoctomys – were named following the discovery of two type species in Argentina by naturalist Michael A. Mares. P. aureus was discovered in Catamarca Province of northwestern Argentina. It is found only over 10 square miles of salt desert, one of the most restricted ranges of all mammals. S. loschalchalerosorum was discovered in the Gran Chaco thorn forest.[15]
Brucepattersonius spp. Brucies 2000 Brazil Brucies (Brucepattersonius) are ground-dwelling Brazilian rodents, related to South American grass mice, belonging to a genus described in 1998. In 2000 three new species were named - the Guaraní brucie (B. guarani), the Misiones brucie (B. misionensis) and the Arroyo of Paradise brucie (B. paradisus) - bringing the number of known species to eight.[16]
