The streaked dwarf porcupine (Coendou ichillus) is a porcupine species in the family Erethizontidae. [2] It is known from the lowlands (below an altitude of 400 m) of eastern Ecuador, and may be present in Peru as well. [1] It appears to be nocturnal and arboreal in its habits. [1]

This species was formerly sometimes assigned to Sphiggurus, [2] a genus no longer recognized since genetic studies showed it to be polyphyletic. [3] Its closest relatives are the frosted hairy dwarf porcupine (Coendou pruinosus) and the brown hairy dwarf porcupine (Coendou vestitus). [3]

Porcupines are large rodents with coats of sharp spines, or quills, that protect them against predation. The term covers two families of animals: the Old World porcupines of family Hystricidae, and the New World porcupines of family, Erethizontidae. Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of rigid or semi-rigid quills, which are modified hairs composed of keratin. Despite this, the two groups are distinct from one another and are not closely related to each other within the Hystricognathi. The largest species of porcupine is the third-largest living rodent in the world, after the capybara and beaver.

<span class="mw-page-title-main">New World porcupine</span> Family of rodents

The New World porcupines, family Erethizontidae, are large arboreal rodents, distinguished by their spiny coverings from which they take their name. They inhabit forests and wooded regions across North America, and into northern South America. Although both the New World and Old World porcupine families belong to the Hystricognathi branch of the vast order Rodentia, they are quite different and are not closely related.

The Brazilian porcupine is a porcupine found in Brazil, Argentina, Colombia, Venezuela, Guyana, French Guiana, Peru, Paraguay, Suriname, Bolivia and Trinidad, with a single record from Ecuador. It inhabits tropical forests at elevations up to 1500 m.

The bristle-spined rat is an arboreal rodent from the Atlantic forest in eastern Brazil. Also known as the bristle-spined porcupine or thin-spined porcupine, it is the only member of the genus Chaetomys and the subfamily Chaetomyinae. It was officially described in 1818, but rarely sighted since, until December 1986, when two specimens - one a pregnant female - were found in the vicinity of Valencia in Bahia. Since then it has been recorded at several localities in eastern Brazil, from Sergipe to Espírito Santo, but it remains rare and threatened due to habitat loss, poaching and roadkills.

The prehensile-tailed porcupines or coendous are found in Central and South America. Two other formerly recognized Neotropical tree porcupine genera, Echinoprocta and Sphiggurus, have been subsumed into Coendou, since Sphiggurus was shown by genetic studies to be polyphyletic, while Echinoprocta nested within Coendou.

The Bahia porcupine, is a New World porcupine species in the family Erethizontidae endemic to the Atlantic Forest of southeastern Brazil. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. Sphiggurus pallidus, formerly considered a separate species but known from two young specimens only, is a synonym of this species.

Roosmalen's dwarf porcupine is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality. It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens. It was soon assigned to the genus Sphiggurus, although this genus was not recognized by the authors. Genetic studies in 2013 have since showed Sphiggurus to be polyphyletic. Nonetheless it is commonly classified as Sphiggurus roosmalenorum. Coendou roosmalenorum may be misspelled due to a conflicting basionym combination.

The black dwarf porcupine, also known as Koopman's porcupine, is a porcupine species from the New World porcupine family endemic to northern Brazil. It occurs in the Amazon rainforest east of the Madeira River and south of the Amazon River. It inhabits primary forest and possibly second growth. It was described as Coendou koopmani by Charles O. Handley Jr. and Ronald H. Pine in 1992, but was subsequently found to be identical to a species described in 1818. It is nocturnal and herbivorous.

<span class="mw-page-title-main">Brown hairy dwarf porcupine</span> Species of rodent

The brown hairy dwarf porcupine is a species of rodent in the family Erethizontidae. Found in the Andes in Colombia and Venezuela, its natural habitat is subtropical or tropical moist lowland forests. It is not easy to study as it is only known from a few specimens and wasn't recorded from 1925 until the 2000s. The porcupine is nocturnal and arboreal, feeding on leaves, shoots, and fruits. Habitat loss severely threatens it and it may even be extinct. Formerly listed as vulnerable, it is now designated data deficient. It is not known from any protected areas or conservation measures.

The frosted hairy dwarf porcupine is a porcupine species in the family Erethizontidae from Colombia and northern and eastern Venezuela. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. The species lives in lowland tropical rainforest and cloud forest at elevations from 50 to 2,600 meters. Its karyotype has 2n = 42 and FN = 76. Its closest relative is the brown hairy dwarf porcupine.

The Andean porcupine or Quichua porcupine is a species of rodent in the family Erethizontidae. It is found in the Andes of northern Ecuador and Colombia as well as in Panama. This porcupine is little known, but is probably arboreal, nocturnal and solitary like its relatives. The species is thought to be uncommon to rare and the population decreasing. It is threatened by deforestation, habitat fragmentation and agriculture.

The Santa Marta porcupine is a rodent in the family Erethizontidae. It is known from dry forests on the lower slopes of the Sierra Nevada de Santa Marta and Serranía del Perijá mountains of northern Colombia, at altitudes below 500 and 1100 m, respectively, and intervening lowlands, and may also be present in nearby parts of Venezuela. It has been described as a subspecies of C. prehensilis, although the latter may be a species complex. Its karyotype has 2n = 74, FN = 82.

Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans.

Coendou speratus, known locally as coandumirim and commonly as the dwarf porcupine, is small porcupine of the Coendou genus found in northeastern Brazil. This small porcupine has a long tail and a spiny appearance as its dorsal fur is not long. It's dorsal colouring is blackish which contrasts with the brownish tips of its quills. It is distinguished from Coendou nycthemera by its tricolored quills whereas nycthemera is bicoloured.
