As a result of our taxonomic study of the genus Epistrophe (Walker) in Korea, we recognized a total of 16 species including seven putative new species (code names are temporarily given from A to F). We also conducted a DNA barcoding analysis of 25 nominal species and 130 samples of Epistrophe. In our barcoding analysis, despite insufficient bootstrap support, Epistrophe formed a cluster with two genera, Epistrophella and Leucozona, topologically supporting their close relationships. Our analysis also showed some interesting results worthy of attention: First, at least two distinct cryptic species were found within the E. grossulariae cluster. Second, the taxon identified as E. nitidicollis seems to represent at least three distinct species. Third, three BOLD-deposited European samples listed as E. olgae showed almost identical barcode sequences with the European E. nitidicollis.
