The Bahia porcupine (Coendou insidiosus), is a New World porcupine species in the family Erethizontidae endemic to the Atlantic Forest of southeastern Brazil.[2] It was formerly sometimes assigned to Sphiggurus,[2] a genus no longer recognized since genetic studies showed it to be polyphyletic.[3]Sphiggurus pallidus, formerly considered a separate species but known from two young specimens only, is a synonym of this species.[1]
