 When American zoologists Voss and Carleton restudied Winge's material in a 1993 paper, they were unable to find any consistent differences between the two and accordingly considered them to pertain to the same species.In addition, they reviewed the differences between this species and other "Holochilus" and concluded that these were significant enough to place the former in a distinct genus, which they named "Lundomys" after Lund, who had collected the original material.Since then, the species has been known as "Lundomys molitor".
