Tribes

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 (the Talpinae) 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.

They are found in temperate North America and parts of China. In North America, they exist virtually everywhere soil conditions permit except northern Canada and those areas of northeastern Mexico where the soil is too sandy. Despite this subfamily being referred to as "New World moles", there are also two species in the mountains of China, each in their own monotypic genus. Morphological and paleontological analyses indicate that both tribes in the subfamily originated in Eurasia during the Oligocene and migrated to North America during the Neogene, with the Condylurini later going extinct throughout their Eurasian range. The Scalopini also migrated at least two different times from North America back to Eurasia, with the two Chinese species likely originating from this. [1] [2] [3] [4] In addition, phylogenetic and morphological evidence supports the Condylurini not belonging in the Scalopinae, and occupying a much more basal position in Talpidae. [4]

Taxonomy

The Scalopininae are divided into two tribes, six genera, and nine species:

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.

<span class="mw-page-title-main">Eulipotyphla</span> Order of 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.

<span class="mw-page-title-main">Talpidae</span> Family of small insectivorous mammals

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.

<i>Condylura</i> Genus of mammal

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.

<span class="mw-page-title-main">Talpinae</span> Subfamily of mammals

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.

<span class="mw-page-title-main">Desman</span> Subfamily of Eurasian insectivores

Desmans are diving insectivores of the tribe Desmanini in the mole family, Talpidae.

<i>Uropsilus</i> Genus of mammals

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.

<i>Neurotrichus</i> Genus of mammals

Neurotrichus is a genus of shrew-like moles. It is classified, together with the fossil genus Quyania, in the tribe Neurotrichini of the subfamily Talpinae. The only living species is the American shrew-mole (N. gibbsii) of the northwestern United States and British Columbia. A fossil species, Neurotrichus columbianus from the Hemphillian of Oregon, was placed in the genus in 1968, but this animal is now thought to be more closely related to the Chinese fossil genus Yanshuella.

<span class="mw-page-title-main">Hairy-tailed mole</span> Species of mammal

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.

<span class="mw-page-title-main">Gansu mole</span> Species of mammal

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.

<span class="mw-page-title-main">Inquisitive shrew mole</span> Species of mammal

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.

<i>Urotrichus</i> Genus of mammals

Urotrichus is a genus of talpid that contains a single living species, the Japanese shrew mole (Urotrichus talpoides). Two fossil species are also known.

<span class="mw-page-title-main">Japanese shrew mole</span> Species of mammal

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".

<i>Hyopsodus</i> Extinct genus of mammals

Hyopsodus is a genus of extinct early ungulate mammal of the family Hyopsodontidae, a group associated with or basal to the Perissodactyla. It was the small mammal with skull of about 6 cm in length. Fossils of this genus have been found in the Eocene of North America, especially the Bighorn Basin region of the United States. It has also been found in Eurasia.

<span class="mw-page-title-main">Urotrichini</span> Tribe of mammals

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.

<span class="mw-page-title-main">Scalopini</span> Tribe of mammals

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.

<span class="mw-page-title-main">Ognev's mole</span> Species of mammal

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.

<span class="mw-page-title-main">Medog mole</span> Species of mammal

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.
