Black tailed hairy dwarf porcupine

Template:Taxobox s

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 (Coendou pruinosus), the brown hairy dwarf porcupine (Coendou vestitus) and the streaked dwarf porcupine (Coendou ichillus).
