Kim & Bae is very similar in appearance to the other four species: O. arcuella (Clerck), O. captiosana (Falkovitsh), O. oculata Kim, Byun & Bae and O. subtilana (Falkovitsh), but it can be distinguished by its genitalia. In the male genitalia, the new species has a narrow uncus and a folded line of stout spines at the base of the cucullus. In the female genitalia, the sterigma has two thick, curved lines and the ostium is characterized the rounded plates projecting from both sides.	en	Kim, Jeong-Nam, Bayarsaikhan, Ulziijargal, Lee, Tak-Gi, Cha, Yeong-Bin, Kim, Hanul, Bae, Yang-Seop (2025): A new species of Olethreutes Hübner, 1822 (Lepidoptera, Tortricidae, Olethreutinae) from Korea, with diagnosis of four allied species.
