We present the results obtained from 12 small-mammal surveys conducted between 1996 and 2013 in “Finca Las Capillas”, province of Jujuy, Argentina. This region has been formally recognized as an “Area of Importance for the Conservation of Bats” (AICOM) based on the diversity of species detected in our previous studies. This site in the Yungas forests of northwestern Argentina still maintains an excellent conservation status due to restrictions to human activities involving deforestation and limitations to cattle-raising imposed 50 years ago. A total of 39 species belonging to three orders, namely, Didelphimorphia, Chiroptera and Rodentia, were recorded. The species accumulation curve revealed that our records represent 83–95% of the community, and with high diversity indexes. Several of the genera and species that we recorded from our collection trips have been included in the fauna of Argentina. Our previous studies and the present findings provide new records for the province or significant extensions to previously known distributions of several taxa of small mammals. These results show that the site represents an icon for conservation in such a fragmented and exploited area as the Yungas in Argentina today.
