The shrew moles or shrew-like moles (Uropsilus) [1] are shrew-like members of the mole family of mammals endemic to the forested, high-alpine region bordering China, Myanmar, and Vietnam. They possess a long snout, a long slender tail, external ears, and small forefeet unspecialized for burrowing. Although they are similar to shrews in size, external appearance, and, presumably, ecological habits, they are nevertheless talpids and considered true moles, as they share a full zygomatic arch with all other moles, while this arch is completely absent in shrews. [2]
The genus is the only one of the subfamily Uropsilinae, which is one of the three main subfamilies of Talpidae, the other two being Talpinae, or Old World moles and relatives; and the Scalopinae, or New World moles. Although little is currently known regarding any aspect of their natural history, the Uropsilinae are thought to be the most ancestral group of moles, and as such, very similar to the primitive talpid from which all Talpidae have evolved. Uropsilus is thought to be a relict genus; despite the small distribution of the modern-day species, the subfamily once had a much wider range throughout Eurasia. [3]
The genus contains the following species: [4]
Although each species' official English common name still calls them "shrew moles", [4] Uropsilus today are referred to as "shrew-like moles" to distinguish them from other shrew moles, Neurotrichus gibbsii of North America and the Urotrichini, or Japanese shrew moles, both of which are morphologically quite different from Uropsilus and are grouped with the Old World Moles and relatives. As a result, the term "shrew-like moles" has been used to refer to Uropsilus, although specific species are still called "shrew moles".
Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging.
The order Insectivora is a now-abandoned biological grouping within the class of mammals. Some species have now been moved out, leaving the remaining ones in the order Eulipotyphla within the larger clade Laurasiatheria, which makes up one of the basal clades of placental mammals.
Eulipotyphla is an order of mammals suggested by molecular methods of phylogenetic reconstruction, which includes the laurasiatherian members of the now-invalid polyphyletic order Lipotyphla, but not the afrotherian members.
Golden moles are small insectivorous burrowing mammals endemic to Sub-Saharan Africa. They comprise the family Chrysochloridae and as such they are taxonomically distinct from the true moles, family Talpidae, and other mole-like families, all of which, to various degrees, they resemble as a result of evolutionary convergence. There are 21 species. Some are relatively common, whereas others are rare and endangered.
The clade Afrosoricida contains the golden moles of Southern Africa, the otter shrews of equatorial Africa and the tenrecs of Madagascar. These three groups of small mammals were for most of the 19th and 20th centuries regarded as a part of the Insectivora or Lipotyphla, but both of those groups, as traditionally used, are polyphyletic.
The family Talpidae includes the moles who are small insectivorous mammals of the order Eulipotyphla. Talpids are all digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere of Eurasia and North America, and range as far south as the montane regions of tropical Southeast Asia.
The subfamily Talpinae, sometimes called "Old World moles" or "Old World moles and relatives", is one of three subfamilies of the mole family Talpidae, the others being the Scalopinae, or New World moles, and the Uropsilinae, or shrew-like moles.
A shrew mole or shrew-mole is a mole that resembles a shrew. Species with this name include:
Soricomorpha is a formerly used taxon within the class of mammals. In the past it formed a significant group within the former order Insectivora. However, Insectivora was shown to be polyphyletic and various new orders were split off from it, including Afrosoricida, Macroscelidea, and Erinaceomorpha, with the four remaining extant and recent families of Soricomorpha shown here then being treated as a separate order. Insectivora was left empty and disbanded.
The white-tailed mole is a species of mammal in the family Talpidae. It is found in Bangladesh, China, India, and Myanmar. This species are endemic to East Asia and exhibit limited distributions. It is the only species in the genus Parascaptor.
The Gansu mole is a species of mammal in the family Talpidae endemic to central China, where it occurs in Shaanxi, Gansu, Sichuan, and Qinghai. It is the only species in the genus Scapanulus.
The gracile shrew mole is a species of mammal in the family Talpidae. It is endemic to China; populations known from Myanmar likely represent other species.
The inquisitive shrew mole is a species of mammal in the family Talpidae. It is only known from Yunnan province of China, although its range is thought to extend over the border into Myanmar.
Urotrichini is a tribe of the mole family, and consists of Japanese and American shrew-moles. They belong to the Old World moles and relatives branch of the mole family (Talpidae). There are only two species, each of which represents its own genus. The name "shrew-moles" refers to their morphological resemblance to shrews, while generally being thought of as "true moles". The species are the Japanese shrew mole, True's shrew mole and American shrew mole.
The Scalopinae, or New World moles, are one of three subfamilies of the family Talpidae, which consists of moles and mole-like animals; the other two subfamilies being the Old World talpids and the Chinese shrew-like moles (Uropsilinae). The Scalopinae are the only Talpidae subfamily to consist entirely of undisputed moles and no mole-like close relatives such as shrew-moles or desmans.
The black-backed shrew mole is a species of mammal in the family Talpidae. It is endemic to China, where it is only known from the vicinity of Mucheng in Yunnan Province.
The Snow Mountain shrew mole is a species of mammal in the family Talpidae. It is native to Yunnan Province in China and potentially Myanmar. Its common name references Jade Dragon Snow Mountain, which is the type locality of the species. Aside from there, the only other confirmed specimen is from Cang Mountain.
The Dabie Mountains shrew mole is a species of mammal in the family Talpidae and genus Uropsilus. It is endemic to Anhui Province in China, where, as its name suggests, it is only known from the Dabie Mountains.
The Fansipan shrew mole is a shrew-like mole native to Vietnam.
The Huangang shrew mole is a shrew-like mole native to China.
