The frosted hairy dwarf porcupine (Coendou pruinosus) 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.[1] The species lives in lowland tropical rainforest and cloud forest at elevations from 50mto2600mm (160feetto8,500feetm). Its karyotype has 2n = 42 and FN = 76. Its closest relative is the brown hairy dwarf porcupine (Coendou vestitus).
