The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies.
The Muridae, or murids, are either the largest or second-largest family of rodents and of mammals, containing approximately 870 species, including many species of mice, rats, and gerbils found naturally throughout Eurasia, Africa, and Australia.
The Nesomyidae are a family of African rodents in the large and complex superfamily Muroidea. It includes several subfamilies, all of which are native to either continental Africa or to Madagascar. Included in this family are Malagasy rodents, climbing mice, African rock mice, swamp mice, pouched rats, and the white-tailed rat.
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
The Cairo spiny mouse, also known as the common spiny mouse, Egyptian spiny mouse, or Arabian spiny mouse, is a nocturnal species of rodent in the family Muridae. It is found in Africa north of the Sahara Desert, where its natural habitats are rocky areas and hot deserts. It is omnivorous, feeding on seeds, desert plants, snails, and insects. It is a gregarious animal and lives in small family groups. It is the first and only known rodent species that exhibit spontaneous decidualization and menstruation.
The beaded hylomyscus or beaded wood mouse is a species of rodent in the family Muridae. It is found in Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon, and Uganda. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
Hylomyscus is a genus of rodent in the family Muridae endemic to Africa.
Mastomys is a genus of rodent in the family Muridae endemic to Africa. It contains eight species:
The dwarf multimammate mouse is a species of rodent in the family Muridae. It is the only member of the genus Serengetimys; it was formerly classified in the genus Mastomys.
The Yemeni mouse is a species of rodent in the family Muridae. It is found in Saudi Arabia and Yemen. It is the only modern member of the tribe Praomyini to be found outside of Africa.
The Angolan multimammate mouse is a species of rodent in the family Muridae. It is found in Angola and Democratic Republic of the Congo. It was formerly classified in the genus Myomyscus but has been reclassified into the genus Mastomys. Its natural habitats are dry savanna and moist savanna.
Brockman's rock mouse, or Brockman's myomyscus is a species of rodent in the family Muridae. It is found in Central African Republic, Ethiopia, Kenya, Somalia, Sudan, Tanzania, Uganda, and possibly Republic of the Congo. Its natural habitats are dry savanna and rocky areas.
Verreaux's mouse or Verreaux's white-footed rat is a species of rodent in the family Muridae. It is the only species in the genus Myomyscus. Other species that had been previously assigned to Myomyscus are now considered to belong to the genera Mastomys, Ochromyscus, Praomys and Stenocephalemys.
The Ethiopian amphibious rat, also known as the Ethiopian water mouse, is an insectivorous and semiaquatic species of rodent in the monotypic genus Nilopegamys of the family Muridae. There has only been one known specimen. It was found along the Lesser Abay River near its source at an altitude of 2600 m in the highlands of northwestern Ethiopia in 1928. N. plumbeus is considered to be the most aquatically adapted African murid; its unusually large brain is thought to be one consequence of this lifestyle. The species is considered to be critically endangered or possibly extinct, since its habitat has been severely damaged by overgrazing and monoculture.
Petromyscus is a genus of rodent in the family Nesomyidae. It is so distinct from other rodents that it is placed as the only genus in subfamily Petromyscinae. In previous classifications, Delanymys brooksi has also been placed in the subfamily. They are found in southwestern Africa. These animals have a sharp lower point to their V-shaped infraorbital canal. Their molars are intermediate between the ancestral cricetid style tooth and the dendromurine style tooth.
The delectable soft-furred mouse or East African praomys is a species of rodent in the family Muridae. It is the only member of the genus Montemys; it was formerly classified in the genus Praomys.
Nannomys is a subgenus of the rodent genus Mus, the mice. They are known as the African pygmy mice. These species are native to sub-Saharan Africa, where they can be found in many types of habitat. There are 20 species.
Congomys is a genus of rodent in the family Muridae. Both species in this genus were formerly classified in Praomys, and both are endemic to the Democratic Republic of Congo.
The Chingawa forest rat is a species of rodent endemic to Ethiopia. It is the only member of the monotypic genus Chingawaemys. It was only described in 2021, when it was discovered during a broad phylogenetic analysis of the tribe Praomyini.
Praomyini is a tribe of muroid rodents in the subfamily Murinae. Species in this tribe are found mostly throughout Sub-Saharan Africa, but one species is found in North Africa, and another is found in the Arabian Peninsula.
