Four newly recorded species with a note on insect fauna from the Dokdo Islands, Korea

Dokdo is a group of Korean oceanic islands located in the East Sea along with the island of Ulleungdo. It is of geological and biological interest due to oceanic islands that were formed earlier than other volcanic islands in the region, such as Jejudo and Ulleungdo. To date, the 156 species found on Dokdo have been classified into 75 families within 10 orders (with the exception of Entomobryomorpha and unidentified species). In this study, we report the discovery of four insect species unrecorded in the Dokdo Islands, thereby taking the total insect fauna of these islands to 160 species in 76 families within 10 orders.
