Taxonomy notes

Some authors have questioned whether Caluromysiops should be considered distinct from Caluromys (e.g., Cabrera 1958; Izor and Pine 1987), but morphological and single-gene molecular data (cytochrom b and various nulcear gene; Jansa and Voss 2000; Voss and Jansa 2009; Amador and Giannini 2016) support the reciprocal monophyly and sister relationship between the two genera. Conversely, some authors have also treated the genus as a separate subfamily (Caluromysiopsinae; Hershkovitz 1992). The specific epithet has been spelt 'irrupta' since the species was described (Sanborn 1951), but is an adjective and should be changed to 'irruptus' to match the masculine gender of the genus. Monotypic.
