A taxonomic review on the Korean Lymantria Hübner, 1819 was conducted. In a result, a total of nine species under four subgenera including two new recorded species were detected as followings: L. dispar asiatica Vnukovskij, 1926, L. xylina Swinhoe, 1903, L. monacha (Linnaeus, 1758), L. minomonis Matsumura, 1933, L. sugii Kishida, 1986, L. lucescens (Butler, 1881), L. mathura Moore, 1865, L. fumida Butler, 1877, and L. bantaizana Matsumura, 1933. Of the two unrecorded species, L. minomonis was found only in Is. Bogildo of Jeollanam-do, the southern part of Korea, and the other one, L. sugii was collected in the middle part of Korea. On the two species, L. xylina and L. fumida, the Korean specimens could not be examined through this study. Therefore, we considered that the two species might be excluded from the Korean Lymantria fauna. Each species was identified on the basis of wing pattern and genitalia of male/female adult. We provided diagnosis, male/female adult habitus photos, male genitalia photos, and female ovipositor photos.
