Thrichomys
''Thrichomys'' is a genus of South American rodents in the family Echimyidae. It contains at least five species, found in Bolivia, Brazil and Paraguay. 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 Phylogeny The closest relatives of the genus ''Thrichomys'' are two clades consisting of pairs of Myocastorini genera: ''Callistomys'' (the painted tree-rat) and ''Myocastor'' (the coypu or nutria) in one clade, and ''Hoplomys'' (the armored rat) and ''Proechimys'' in the other.

Common Punaré
The common punaré (''Thrichomys apereoides''), is a species of spiny rat endemic to Brazil. Description Like other members of the genus ''Thrichomys'', but unlike all other species of spiny rat, common punarés have no spines, and instead have a thick pelt of soft fur, which also extends for the full length of the tail. The fur is greyish-brown over most of the body, with whitish underparts and ears. There are also three pairs of small white spots on the face; one each above and below the eyes, and one at the base of the ears. They are the size of a large rat, measuring in length, not counting the tail. On average, they weigh , although males are slightly larger than females. Females have four teats, with one pair just behind the forelegs, and another in front of the hips. Distribution and habitat The common punaré is found only in eastern Brazil, where it inhabits a belt of relatively open caatinga and cerrado vegetation between the Amazonian and Atlantic Forests. It is f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highlands Punaré
The highlands punaré (''Thrichomys inermis'') is a caviomorph rodent of South America from the spiny rat family. It is endemic to gallery forest, savanna and rocky outcrop habitats in Bahia State within the Caatinga ecoregion of eastern Brazil at elevations from 260 m to 1030 m. It sometimes nests and often takes refuge in crevices in rock formations, as means of both predator avoidance and moderating temperature extremes. The species tolerates a degree of habitat disturbance. Although hunted, it is considered common throughout its range. Its karyotype has 2n = 26 and FN = 48. The etymology of the species name corresponds to the Latin word '' inermis'' meaning ''unarmed, defenceless'' — itself constructed from the prefix '' in-'' meaning ''without'' and the stem ''arma Arma, ARMA or variants, may refer to: Places * Arma, Kansas, United States * Arma, Nepal * Arma District, Peru * Arma District, Yemen * Arma Mountains, Afghanistan People * Arma people, an ethnic group of ...

Paraguayan Punaré
The Paraguayan punaré (''Thrichomys pachyurus'') is a caviomorph rodent of South America from the spiny rat family. With its skull averaging 55 mm long, it is the largest species in the genus ''Thrichomys''. It is found in savannas and forest edges in southwestern Brazil and northern Paraguay within the cerrado ecoregion. The species tolerates a degree of habitat disturbance, and is considered abundant throughout its range. Its karyotype has 2n = 34 and FN (fundamental number A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes.

Sao Lourenço Punaré
''Thrichomys laurentius'', the Sao Lourenço punaré, is a South American caviomorph rodent of the spiny rat family. It was formerly considered a subspecies of '' T apereoides''. It is endemic to the northern Caatinga ecoregion An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources.

Myocastorini
Myocastorini is a tribe of echimyid rodents, proposed in 2017, and containing the five extant genera '' Callistomys'', '' Hoplomys'', '' Myocastor'', ''Proechimys ''Proechimys'' is a genus of South American South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described ...'', and '' Thrichomys''. Definition Myocastorini members share long upper incisor roots (except ''Callistomys''), and mid- to long-sized lower incisor roots. These five genera share either four (''Callistomys'', ''Thrichomys'') or five (''Hoplomys'', ''Myocastor'', ''Proechimys'') lophids on the lower deciduous fourth premolar, three roots anchoring the upper molars, and well-connected lophs on cheek teeth. Members display a variety of lifestyles including terrestrial (''Hoplomys'', ''Proechimys'', ''Thrichomys''), arboreal (''Callistomys''), and amphibious (''Myocasto ...

Proechimys
''Proechimys'' is a genus of South American South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a considerably smaller portion in the Northern Hemisphere. It can also be described as the southern Subregion#Americas, subregion o ... spiny rats of the family Echimyidae. All species of the genus are terrestrial. In the lowland Neotropical forests, ''Proechimys'' rodents are often the most abundant non-volant mammals. They are recognizable by reason of their elongated heads and long rostra, large and erect ears, narrow and long hind feet, and tails always shorter than head-and-body lengths. The dorsal pelage comprises a mixture of expanded, varyingly stiffened spines (or aristiforms) — hence the vernacular name of spiny rats — and soft hairs (or setiforms). ''Proechimys'' is the most speciose genus of the rodent family Echimyidae, with 25 species recognized, followed by '' Phyllomys'' with 13 species, and '' Tri ...
