The 2 known species of the phyllotine rodent Tapecomys, the typical, Tapecomys primus Anderson and Yates, 2000 and Tapecomys wolffsohni (Thomas, 1902), have been cited for Argentina, and reported to be sympatric in 1 locality in the Yungas of Jujuy. A review of these materials suggest that the reference for T. wolffsohni is incorrect. In this context, only 1 species—T. primus—is present in 4 localities in the montane forests of Jujuy. A record for T. wolffsohni from 1 locality in Salta, is discussed based on a critical assessment of the morphological variation of these species. Currently it is not possible to confirm that T. wolffsohni inhabits the country.
