A newly-recorded species, Roeslerstammia erxlebella (Fabricius, 1787) (Lepidoptera, Roeslerstammiidae) from Korea, with a key to species of the genus and DNA barcoding analysis

The present study reports the first record of <i>Roeslerstammia erxlebella</i> in Korea, specifically from Odae-san National Park. This paper constitutes a review of the taxonomic history of the family Roeslerstammiidae and the genus <i>Roeslerstammia</i>. A thorough taxonomic account of the recently documented species, <i>R. erxlebella</i>, is presented, accompanied by a taxonomic key and an illustrated map delineating the geographical distribution of the genus <i>Roeslerstammia</i>. Furthemore, the DNA Barcode data of a Korean individual was made available, alongside public data from BOLD systems. The DNA Barcoding analysis further indicates that the Korean individual is <i>R. erxlebella</i>.
