Roosmalen's dwarf porcupine (Coendou roosmalenorum) is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality.[2][3] It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens.[3] It was soon assigned to the genus Sphiggurus,[2] although this genus was not recognized by the authors.[3] Genetic studies in 2013 have since showed Sphiggurus to be polyphyletic (this taxon was omitted from the study).[4] Nonetheless it is commonly classified as Sphiggurus roosmalenorum.[5][6]Coendou roosmalenorum may be misspelled due to a conflicting basionym combination.[7]
