The Bahia porcupine (Coendou insidiosus), 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.[1] Sphiggurus pallidus, formerly considered a separate species but known from two young specimens only, is a synonym of this species.
