Gymnures, also called hairy hedgehogs or moonrats, are mammals belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla. Gymnures resemble rats but are not closely related as they are not rodents; they are instead closely related to hedgehogs, which also belong to Erinaceidae. They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews.
Erinaceidae is a family in the order Eulipotyphla, consisting of the hedgehogs and moonrats. Until recently, it was assigned to the order Erinaceomorpha, which has been subsumed with the paraphyletic Soricomorpha into Eulipotyphla. Eulipotyphla has been shown to be monophyletic; Soricomorpha is paraphyletic because both Soricidae and Talpidae share a more recent common ancestor with Erinaceidae than with solenodons.
Hylomys is a small genus of the family Erinaceidae. Hylomys species, like all species in the subfamily Galericinae, are known as gymnures or moonrats. Their closest relatives include the fossil Lantanotherium and Thaiagymnura and the living Neotetracus and Neohylomys. Members of this genus are found in Southeast Asia and Eastern Asia.
The dwarf gymnure is a gymnure found only at Mount Kerinci, Sumatra, Indonesia. It is listed by the International Union for Conservation of Nature as a critically endangered species due to a restricted range.
Cephalotaxus hainanensis is a species of conifer known by the common name Hainan plum-yew. It is native to southern China, southeastern Tibet, and Myanmar, Thailand, and Vietnam in northern Indochina.
The Hainan knobby newt is a species of salamander in the family Salamandridae. It is found only in the island of Hainan, China. It is known from the Wuzhi Mountains, Diaoluoshan, and Jianfengling. All these locations are nature reserves. Nevertheless, the species is threatened by habitat loss and degradation due to agriculture, clear-cutting and infrastructure development for tourist activities.
The Hainan partridge is a species of bird in the family Phasianidae. It is endemic to Hainan Island, China. Its natural habitats are primary evergreen forests. It is threatened by habitat loss and has been assessed as a vulnerable species.
Chuniophoenix hainanensis, also known as Hainan fan palm, is a species of palm tree. It is endemic to China.
Amolops hainanensis is a species of frog in the family Ranidae that is endemic to southwestern and central Hainan, China. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss. It is a sister taxa to both A. torrentis and A. daiyunnensis.
Odorrana hainanensis is a species of frogs in the family Ranidae that might be endemic to Hainan Island, China; there is one record from Guangxi. Prior to its description in 2001, it was confused with Odorrana andersonii.
The shrew gymnure, or shrew hedgehog, is a species of mammal in the family Erinaceidae and is the only extant species in the genus Neotetracus. It is found in China, Myanmar, and Vietnam.
The Dinagat gymnure is a species of mammal in the family Erinaceidae. It is endemic to the Philippines.
Podogymnura is a genus of mammal in the family Erinaceidae. It contains the following species:
Podogymnura truei, also known as the Mindanao gymnure, Mindanao moonrat, or Mindanao wood shrew, is a mammal of the family Erinaceidae. It is endemic to the Mindanao islands of the Philippines. Erinaceidae is a family of small mammals that include the gymnures, also known as the silky furred moonrats, and the hedgehogs. Animals belonging to this family are significant because they are among the oldest known placental mammals that are alive. Gymnures are relatives of hedgehogs but lack the prickly spines. Four species are categorized in the genus Podogymnura: P. aureospinula, P. intermedia, P. minima, and P. truei. All share a close resemblance to the moonrat Echinosorex gymnura, which is commonly found on the Borneo, Sumatra, and the Malay Peninsulas.
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 long-eared gymnure is a eulipotyphlan that is found in Laos. This specific type of gymnure has long ears and a long skull compared to that of others. It is also recognized for its broad forefeet, stout claws, and naked hindfeet. While it was previously lumped in with the dwarf and short-tailed gymnures of the genus Hylomys, it is now placed in its own genus Otohylomys.
