Gansu mole range |
The Gansu mole (Scapanulus oweni) 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. [2]
Along with the Medog mole (Alpiscaptulus medogensis), which is also found in the mountains of China, the Gansu mole is the only member of the tribe Scalopini to not live in North America. Phylogenetic and fossil evidence indicates that the scalopine moles evolved in Eurasia and migrated to North America during the Neogene; however, the Gansu and Medog moles are not relict Eurasian scalopine moles, but are descendants of North American scalopine moles that migrated back to Eurasia; the hairy-tailed mole (Parascalops breweri) of North America is more closely related to them than it is to the other two North American scalopine genera. [3] [1]
Phylogenetic evidence supports the Gansu and Medog moles being the closest living relatives of one another and diverging the mid-late Miocene, about 11.59 million years ago. It is thought that the uplift of the Tibetan Plateau and the subsequent climate change isolated the two genera in different habitats, leading to their divergence. The habitats for both species may have served as refugia during periods of glaciation, allowing them to persist while most other Eurasian scalopines went extinct. [3]
The morphology of the Gansu mole indicates that it will fall in the Scalopini tribe. All scolopines are distributed in Central America;however, Gansu moles are distributed in the Central and Southwest areas of China. The first specimen of Scapanulus oweni was found by G. Fenwick Owen in 1911 in Gansu, China. The genome of the species is 16,826 bases in length and contains 13 protein-coding genes, 22 transfer genes, 2 ribosomal RNA genes and a displacement loop gene.

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.
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.
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.
Condylura is a genus of moles that contains a single extant species, the star-nosed mole (Condylura cristata) endemic to the northern parts of North America. It is also the only living member of the tribe Condylurini.
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.
The shrew moles or shrew-like moles (Uropsilus) 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.
The hairy-tailed mole, also known as Brewer's mole, is a medium-sized North American mole. It is the only member of the genus Parascalops. The species epithet breweri refers to Thomas Mayo Brewer, an American naturalist.
The insular mole is a species of mammal in the family Talpidae. It is restricted to Hainan Island and Taiwan, where it is also known as the Formosan blind mole. The species was first described by Robert Swinhoe in 1863.
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 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 Japanese shrew mole or himizu (ヒミズ) is a species of mammal in the family Talpidae. It is endemic to Japan and is found on Honshu, Shikoku, Kyushu, Awaji Island, Shodo Island, Oki Islands, Tsushima Island, Goto Islands, Mishima Island, and Awashima Island, but is absent from Hokkaido, which is north of Blakiston's Line. It is one of three Urotrichini and it is the only extant species in the genus Urotrichus. It is common between sea level and approximately 2,000 m. Sometimes this species is called the greater Japanese shrew mole and another species, True's shrew mole, is called the "lesser Japanese shrew mole".
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 Scalopini are a tribe of moles belonging to the family Talpidae. They include all the New World moles apart from the strikingly distinctive star-nosed mole. As the similarity of the names implies, they are the standard form of the Scalopinae, the North American or New World moles, and can be found virtually anywhere north of Northern Mexico and south of Northern Canada where environmental factors permit.
Ognev's mole is a species of mammal in the family Talpidae. It occurs in the southeastern coastal area of the Black Sea from northeastern Turkey to Georgia. It inhabits different habitats associated with moist soils in lowland areas. Little information is available about its life history.
The Talysch mole is a species of mammal in the family Talpidae. It is a small member of the family, which outwardly resembles the Levant mole, but is genetically closer to Père David's mole. It is common on the southwest coast of the Caspian Sea, from southern of Azerbaijan through most of the north of Iran. The habitat includes temperate rainforests and scrub areas. There is little information about the life history of the Talysch mole. It was described in 1945, but had long been considered a subspecies of various other Eurasian moles, and was only recognized as a distinct species in the mid-2010s. No surveys have been carried out to quantify the status of the species.
The Medog mole is a species of mammal in the family Talpidae. It is the only member of the genus Alpiscaptulus. It is endemic to Tibet, where it is only found in the vicinity of Namcha Barwa in Medog County.
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 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.
