Chionomys is a genus of rodent in the family Cricetidae. [1]
Mammal Species of the World and the IUCN recognize the following 3 species: [1]
The American Society of Mammalogists additionally recognizes these two species: [2]
The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae. Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.
Microtus is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. They are stout rodents with short ears, legs and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, root and bark at other times. The genus is also called "meadow voles".
Water voles are large voles in the genus Arvicola. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A water vole found in Western North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus Microtus. Head and body lengths are 12–22 cm, tail lengths are 6.5–12.5 cm, and their weights are 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringes on their feet that improve their swimming ability.
Marmosops is a genus of Neotropical opossums of the family Didelphidae. The genus was originally treated as a subgenus from the genus Marmosa rather than having their own classification. This was changed in 1989 by Gardner and Crieghton, who officially separated the group and made them their own genus. The mix-up between to genera Marmosa and Marmosops was common due to the similar appearances including size and other external features. However, the two groups differ significantly in their integument and in the arrangement of their skull and dentition. The dentition is similar in morphology between the two groups, with the exception of the deciduous lower third premolar varying from one genus to the next. The similarity between the two continues to cause the genus Marmosops to be frequently misidentified due to the lack of knowledge regarding the species along with the overlooked traits that help separate them from other opossums. The Marmosops are also commonly confused with the genus Gracilinanus, but this is quickly ruled out by a large number of differing characteristics. These differences include the arrangement of their digits, caudal scales, and the central hair on the scales changing from a three hairs per follicle to many more. This causes the hair of the Gracilinanus to be thicker and has also found to be heavily pigmented. The last group commonly confused with Marmosops is known as the genus Thylamys. These animals have a contrasting dorsal body pelage and the taxa are actually quite different.
The Balkan snow vole, also known as Martino's snow vole, is the only living member of the genus Dinaromys. The genus name means "Dinaric mouse", referring to the Dinaric Alps, as the species is endemic to the western Balkans of southeast Europe. Eight subspecies of this vole have been recognized, although in 2022 this number was reduced to two subspecies. The Balkan snow vole is a living fossil, the only living species in the tribe Pliomyini, and might arguably better be placed in Pliomys, a genus established for its fossil relatives even before the Balkan snow vole was scientifically described. It was described by husband and wife mammalogists Vladimir Emmanuilovich Martino and Evgeniya Veniaminovna Martino. Others have argued that Pliomys should be treated as entirely separate from Dinaromys, with Dinaromys and P. lenki estimated to have genetically diverged around 4 million years ago based on ancient DNA sequences. The earliest representatives of Dinaromys like Dinaromys allegranzii date to the Early Pleistocene, with Dinaromys also inhabiting the Italian Peninsula until the end of the Late Pleistocene, when it contracted to its current distribution.
Ondatrini is a tribe of semiaquatic rodents in the family Arvicolinae. They are known as muskrats. They are related to voles and lemmings.
Maria Nazareth Ferreira da Silva is a zoologist from Manaus, Brazil.
Alticola is a genus of rodent in the family Cricetidae.
Blanfordimys is a subgenus of voles in the family Microtus. It was formerly considered a distinct genus, but taxonomic studies group it within the Microtus radiation.
The Caucasian snow vole is a species of rodent in the family Cricetidae.
The European snow vole or snow vole is a species of rodent in the family Cricetidae. It has dense, pale grey fur and a pale-coloured tail and can reach about 14 cm (5.5 in) long, with a tail which is 7 cm (2.8 in) long.
The juniper vole is a species of rodent in the family Cricetidae. It is found in Afghanistan, China, Pakistan and Tajikistan. It was formerly classified in the genus Neodon, but genetic evidence indicates that it is classified within the subgenus Blanfordimys in Microtus.
Maximowicz's vole is a species of rodent in the family Cricetidae. It is found in northeastern China, Mongolia, and eastern Russia.
The Duke of Bedford's vole is a species of rodent in the family Cricetidae. After the Liangshan vole was removed from this genus, the Duke of Bedford's vole became the only member of the genus Proedromys. It is found only in mountainous parts of central China. It is a rare species and the International Union for Conservation of Nature has assessed its conservation status as being "vulnerable".
Tarsomys is a genus of rodent in the family Muridae found exclusively in Mindanao, Philippines.
Arvicolini is a tribe of voles in the subfamily Arvicolinae.
Neodon is a genus of rodent in the family Cricetidae. Species within Neodon are classified as relics of the Pleistocene epoch because the occlusal patterns resemble the extinct Allophaiomys.
Alexandromys is a genus of voles in the subfamily Arvicolinae, formerly a subgenus of the genus Microtus. Species in this genus are:
Microtini is a tribe of voles in the subfamily Arvicolinae.
