They are as follows: Thrichomys apereoides - Common punaré Thrichomys fosteri - Foster's punaré Thrichomys inermis - Highlands punaré Thrichomys laurentius - Sao Lourenço punaré Thrichomys pachyurus - Paraguayan punaré

thumb|Spotted ground squirrels Pygmy ground squirrels are small ground squirrels in the genus Xerospermophilus, family Sciuridae, containing four species from Mexico and the United States. The members of this genus were formerly placed in the large ground squirrel genus Spermophilus. Since DNA sequencing of the cytochrome b gene showed that Spermophilus (as then defined) was paraphyletic to the prairie dogs and marmots, this group is now separated, along with six other genera. Within the genus, the Mohave ground squirrel and the round-tailed ground squirrel were thought to be close relatives,

Isolobodon is an extinct genus of rodent in the subfamily Capromyinae. It contains the following species: Montane hutia (Isolobodon montanus) Puerto Rican hutia (Isolobodon portoricensis)

Euryoryzomys is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes seven species, which are distributed in South America. Until 2006, its members were included in the genus Oryzomys, but they are not closely related to the type species of that genus, and therefore they were placed in a new genus. They are most closely related to genera like Hylaeamys and Transandinomys; many members of these genera were previously placed in a single species, known as Oryzomys capito. The genus name, Euryoryzomys, combines the name "Oryzomys" with the Ancient Greek word eurus "broad",

Aegialomys is a genus of oryzomyine rodents from the lowlands and mountains of western Peru and Ecuador, including the Galápagos Islands. The species in this genus have historically been placed in Oryzomys, but according to cladistic research, the genus is more closely related to a group containing, among others, Nectomys and Sigmodontomys, than to Oryzomys. The generic name Aegialomys means "coastal mouse" in Ancient Greek ( "coast" and "mouse") and references the mostly coastal occurrence of the genus.

Fukomys is a genus described in 2006 of common mole-rats, containing several species that were formerly placed in the genus Cryptomys; its species are endemic to Africa. The species contained in the genus includes:

Baiyankamys is a genus of amphibious murid rodents. It was originally described, along with the species Baiyankamys shawmayeri by Hinton in 1943 after he found the remains of a single individual in south east of the Bismarck Mountain Range, north east New Guinea. Tate, in 1951 and, Laurie and Hill in 1954, confirmed the existence of both the species and genus.

Cerradomys is a genus of oryzomyine rodents from eastern Bolivia, Paraguay, and central Brazil found in cerrado, Caatinga and Gran Chaco habitats.

Loxodontomys is a genus of South American rodents in the tribe Phyllotini of family Cricetidae. Two species are known, found in Argentina and Chile. They are as follows: Southern big-eared mouse (Loxodontomys micropus) Pikumche pericote (Loxodontomys pikumche)

Ictidomys is a North American genus of rodent in the squirrel family, which contains the thirteen-lined ground squirrel, the Mexican ground squirrel, and the Rio Grande ground squirrel. These species were included in the species-rich ground squirrel genus Spermophilus until molecular data showed that this genus was not a natural, monophyletic grouping. ==Species== {| class="wikitable" |- !

Transandinomys is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes two species—T. bolivaris and T. talamancae—found in forests from Honduras in Central America south and east to southwestern Ecuador and northwestern Venezuela in northern South America. Until 2006, its members were included in the genus Oryzomys, but phylogenetic analysis showed that they are not closely related to the type species of that genus, and they have therefore been placed in a new genus. They may be most closely related to genera like Hylaeamys and Euryoryzomys, which contain very

Heteropsomys is an extinct genus of rodent in the family Echimyidae. It contains the following species: Antillean cave rat (Heteropsomys antillensis) Insular cave rat (Heteropsomys insulans)

Pattonomys is a genus of rodent in the family Echimyidae, named after American mammalogist James L. Patton. It contains the following species: Bare-tailed armored tree-rat (Pattonomys occasius) Speckled spiny tree-rat (Pattonomys semivillosus)

Notocitellus is a genus of ground squirrels, containing two species from Mexico. These species are the tropical ground squirrel (Notocitellus adocetus), and the ring-tailed ground squirrel (N. annulatus). Notocitellus was formerly placed in the large ground squirrel genus Spermophilus, as a subgenus or species group. Since DNA sequencing of the cytochrome b gene has shown Spermophilus to be paraphyletic to the marmots, antelope squirrels, and prairie dogs, it is now separated, along with six other genera. The exact relations of this genus are unclear, though a relation to the antelope squ

Mirzamys is a genus of rodent in the family Muridae endemic to New Guinea. It contains the following species: Mirza's western moss rat (Mirzamys louiseae) Mirza's eastern moss rat (Mirzamys norahae)

Neotamias is a genus of chipmunks within the tribe Marmotini of the squirrel family. It contains 23 species, which mostly occur in western North America. Along with Eutamias, this genus is often considered a subgenus of Tamias.

Soricomys, the shrew-mice, are a genus of rodents in the family Muridae. They are carnivores that feed on invertebrates much like shrews do. An apparently smaller relatives of the true shrew-rats Chrotomys and Rhynchomys, Soricomys are somewhat convergent to the more distantly related Crunomys.

Nannospalax is a genus of rodent in the family Spalacidae, found in eastern Europe and western Asia. It is one of two genera in the blind mole-rats (subfamily Spalacinae), alongside Spalax. Members of this genus are also known as small-bodied mole-rats. As with members of the genus Spalax, they are completely blind, with their eyes being entirely covered by skin.

Dipus, meaning "two foot" in Ancient Greek, is a genus of jerboa. Today only a single species is usually recognized, the northern three-toed jerboa (Dipus sagitta), widespread throughout Central Asia. Some authors recognize a second species, the Qaidam three-toed jerboa (Dipus deasyi) from the Qaidam Basin of western China. The genus has a fossil record that dates back to the Miocene, with several extinct species known from Asia. The oldest dated species is Dipus conditor.

Coryphomys is an extinct genus of rats, known from sub-fossils found on Timor. Its name is Greek for "top-of-the-head mouse" or "summit mouse".

Hypogeomys is a genus of rodents in the family Nesomyidae, found in Madagascar. There is one extant species, the Malagasy giant rat (Hypogeomys antimena), currently an endangered species with a restricted range. There is also another species known from subfossils from a few thousand years ago, Hypogeomys australis. H. antinema measures , making it the largest rodent in Madagascar, while H. australis seems to have been slightly larger.

Eupetaurus is a genus of rodent in the family Sciuridae. Members of this genus are known as woolly flying squirrels. They are large to very large flying squirrels found in the highest rocky cliffs near the treeline of the Himalayas and Tibetan Plateau. Due to the inaccessibility of their montane habitat, they are difficult to study.

The North American porcupine (Erethizon dorsatum) is the only extant species, but at least four extinct relatives are known, the oldest dating to the Late Pliocene. Porcupines entered North America during the Great American Interchange after the Isthmus of Panama rose 3 million years ago. Early species of the genus retained an elongate tail, unlike E. dorsatum.

Rhagamys is an extinct genus of rodents in the subfamily Murinae, the Old World mice and rats. The genus was established by the Swiss zoologist Charles Immanuel Forsyth Major to accommodate Rhagamys orthodon, which is the only species in the genus. It was endemic to the Mediterranean islands of Corsica and Sardinia, descending from Rhagapodemus, which had colonised the islands around 3.6 million years ago. Its closest living relatives are of the genus Apodemus, which includes the field and wood mice.

Tanyuromys is a genus of oryzomyine rodents distributed in mountainous areas from Central America to the western part of South America. The species in this genus have historically been placed in Sigmodontomys, but according to cladistic research, this genus is either sister to the clade containing Sigmodontomys and Melanomys or sister to the extinct Caribbean giant rice rat Megalomys. Along with members of Aegialomys and Melanomys, it occurs at some of the highest elevations known for oryzomines.

Hypnomys, otherwise known as Balearic giant dormice, is an extinct genus of dormouse (Gliridae) in the subfamily Leithiinae. Its species are considered examples of insular gigantism. They were endemic to the Balearic Islands in the western Mediterranean from the Early Pliocene until their extinction around the 3rd millennium BC. They first appeared in the fossil record on Mallorca during the Early Pliocene (around 5 million years ago), presumably as a result to the evaporation of the Mediterranean sea during the Messinian salinity crisis (5.96-5.33 million years ago) connecting the Balearic Is

Neomicroxus is a genus of grass mice. Both species were placed in the genus Akodon. There are two living species:

Heterogeomys are a small genus of rodents commonly known as pocket gophers, though the term applies to all genera within the family Geomyidae. The name pocket gopher was earned for this family because of their fur lined cheek pouches that can be used for carrying food. These pouches can also be turned inside out. Species of Heterogeomys are regarded as pests, one of less than 5% of rodent species classified as pests, and the history of man's a
