Roosmalen's dwarf porcupine

Roosmalen's dwarf porcupine, Coendou roosmalenorum, is a porcupine species from the New World porcupine family endemic to northern Brazil. It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens. It was formerly sometimes assigned to Sphiggurus, a genus no longer recognized since genetic studies showed it to be polyphyletic.
