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 type species, Roeslerstammia erxlebella (Fabricius, 1787) is distributed across the Palaearctic Region, from Europe to Japan. However, the presence of this species has only been confirmed in European countries, Russia and Japan.The present study reports the first record of Roeslerstammia erxlebella in Korea, specifically from Odae-san National Park.

This paper constitutes a review of the taxonomic history of the family Roeslerstammiidae and the genus Roeslerstammia. A thorough taxonomic account of the recently documented species, R. erxlebella, is presented, accompanied by a taxonomic key and an illustrated map delineating the geographical distribution of the genus Roeslerstammia. Furthemore, the DNA Barcode data of a Korean individual was made available, alongside public data from BOLD systems.
