Black-tailed hairy dwarf porcupine
The black-tailed hairy dwarf porcupine, Coendou melanurus, is a South American porcupine species from the family Erethizontidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname and Venezuela.
This species was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic. Its closest relatives are the frosted hairy dwarf porcupine, the brown hairy dwarf porcupine and the streaked dwarf porcupine.
