We need to point out that the checklist by Didmanidze (2004) contains errors such as redundant or missing letters in Latin names, nomenclatural inaccuracies, mistaken authors of species names, omissions, and incomplete or incorrect information about ranges of species. For that reason, we used Tshikolovets & Nekrutenko (2012) as our reference data source. We considered that the aforementioned authors summarised the important publications on the butterfly fauna of the Caucasus.
