Material examined. Table 2 ; Figure 3 . The species could be Didelphis marsupialis Linnaeus, 1758 or Didelphis virginiana Kerr, 1792 . In the study area, there are potentially both species, and although the morphological characteristics allow for the distinction between them (white cheeks and black portion of tail longer than white portion in D. virginiana than in D. marsupialis ; Reid 2009 ), this distinction is not evident in photographs obtained from infrared-illuminated cameratraps. Therefore, we decided to report these 2 species as Didelphis sp.
