Zoological Studies 37(4): 291-301. Nine species of the genus Pammene Hubner are recognized from Korea. Among them, 2 new species, P. (Pammene) blanda and P. (P.) soyoensis, are described, and 5 species, P. (P.) ignorata Kuznetsov, P. (P.) germmana (Hubner), P. (P.) adusta Kuznetsov, P. (P.) shicotanica Kuznetsov, and P. (P.) sp. are newly recorded from Korea. Keys to all known species of the genus, based on the external and male genitalia characters are provided. Illustrations of adults, male abdominal scent organs, and genitalia of both sexes are given. All available host plants are listed. Key words: Taxonomy, Lepidoptera, Tortricidae, Pammene, Korea. Genus Pammene Hubner, [1825] is one of names are as follows: ASTI, Agricultural Science the genera related to Grapholita Treitschke, 1829, and Technology Institute, Suweon; CIS, Center for belonging to the tribe Grapholitini of the subfamily Insect Systematics, Kangwon Natural University, Olethreutinae. The genus is mostly distributed in Chunchon; FRI, Forest Research Institute, Seoul; the Holarctic region, with about 100 species re­ UIB, Department of Biology, University of Inchon, corded from the Old World.

The 1st recorded species from Ko­ rea was P. japonica Kuznetsov, which was in­ cluded in the "Microlepidoptera of Korea" by Park SYSTEMATIC ACCOUNTS (1983), while Byun and Park (1993) recently added Genus Pammene Hubner, [1825] P. orientana Kuznetsov and P. griseana Walsing­ ham.
