Abstract The Korean species of the genus Lobesia Guenee, 1845, are revised. One new species, L. PyiZft)rinis n. sp., is described ancl three species, L. viTulenta Bae & Komai, L. .vasetclai Bae & Kornai and L. aeogopa Meyrick. are newly recorded from Korea.

Key words Lepidoptera, Tortricidae, Olethreutinae, Lobesia, Korea, .

"Microlepidoptera In the of Korea", Park (1983a) recorded two species of the genus Lobesia, i.e., L, coccophcrga Falkovitsh and L.pernzixlana Htibner (=reliqzftzna Hifbner) from Korea, Recently, Bae and Komai (1991) revised Japanese species of this genus and arranged them in two subgenera, i,e., Lobesia Guenee and Nbolobesia Bae & Komai. Generally･, the wing patterns of Lobesia are uniform and genitalic characters are requisite for reliable identification. In the male genitalia (Figs, 7-10), the number of the spine clusters of sacculus (Spci and Spc2), the shape of the cucullus and the aedeagus provide stable characters for identification. In the female genitalia (Figs,11-13), the structure of the sterigma is an important diagnostic character. Secondary sexual organs are well developed in male : a pair of ventral pouches on the 2nd abdominal sternite and

the hair-pencil on the hind tibia. In the present paper we are going to record six species of the genus frorn Korea; one is new to science and three are newly recorded from Korea. External appearance and genitalia are figured if necessary, a short diagnosis and brief remarks are given on morphological differentia, biology and distribution, All the specimens recorded here, including type specimens, will be preserved in Center for Systematics, Kangweon

National University, Korea.

Remarks. This species is allied to yasztdoi Bae & Komai and Pyrijiormis n. sp. and the diagnostic characters will be given in the remarks for ptrijbrmis n. sp, The markings and coloration of the forewing are also similar to those of aeoloPa Meyrick, but this species can be distinguished from the latter by the genital structure, especially in having the shorter aedeagus and arrowhead-shaped signum. This species is recorded from Korea for the first time,

to separate them in external characters. But this species can be distinguished frem L.

viruienla by the shape of female ductus bursae, e.g.,a broad part near ostium, the part being broader than width of lateral lobe of limen. This species is recorded from Korea for the first time,

Remarks, This new species is clesely related to virulenta Bae & Komai, J,asz-td2zi Bae & Komai and reliquana Httbner, They are superficially similar, but P:L･,rij2)rmis may be distinguished from the latter by its more convexed costa and distinct markings of the forewing, and the darker general coloration of the male hindwing. The male genitalia are also similar to those of viralenin, yczsudai and reli4zaana, but differ from them in having the broader valva and shorter cucullus.

EtymolQgy. The specific name is derived from the characteristics of female sterigma:

pyriformis (pear-shaped, i.e., obovoid or narrowly obovoid with a tapering base).
