A nolid species,
(Leech) is reported for the first time from Korea. Two males were collected from Jeju Island, South Korea.
can be distinguished by the bipectinate male antennae, broad frons, long labial palpi, costally dark brownish spot and the rounded dark brownish postmedial line of forewing. In the male genitalia, the long saccus, the slender valve with distally expanded and spine-like harpe and long spinular cornutus of vesica are distinguishing characters. In the female genitalia, the simple sterigma, the long ductus bursae and the large ovate corpus bursae with a lip-shaped signum are distinguishing characters. Diagnosis and description of the species are given with the figures of the male genitalia.
The Nolidae are small to medium sized moths and are esti-mated about 1,400 species in 308 genera. They occur world-wide, but primarily palaeotropical in distribution. The synapo-morphies of the Nolidae include the following characters: the dorsally broadened postspiracular bar at the base of the abdomen, the easily detached tegulae and patagia, an elon-gate retinaculum of male wing, and the ventrally directed M
male genital muscle (Kitching and Rawlins, 1999).
Hübner, one of the largest taxa of Noli-dae, was based on
Linnaeus as the type species, and comprises 203 species worldwide (Beccaloni et al., 2003). The genus is characterized by the bipectinate male antennae, whitish frons, long labial palpi, greyish or light greyish wing ground color with undulating central fascia of forewing, and quadrifine hindwing veation with M
stalked. It is superficially to those of
Walker, but can be distinguished by the shape of the male and female genitalia. The male genitalia of
differ from those of
by the presence of uncus with hairy socii, the absence of subscaphium and the undivided valva. The female genitalia differ from those of
by having the large corpus bursae with two signa (Holloway, 2003; Choi, 2006).
Up to now, a total of 19 species in three genera of Nolidae are recognized in Korea (Oh, 2001; Choi, 2006). Among them 6 species of
(Staudinger). The present study describes a nolid species,
(Leech), for the first time in Korea. Two male specimens were collected at the southern slope of Mt. Halla-san, Jeju-do. Examination of adults including the male and female geni-talia refers to Scoble (1992).

This species can be distinguished by the bipecti-nate male antennae, broad frons with dark ochreous and whitish scales, long labial palpi with distally dilated second segment, and costally dark brownish scales and the dark brownish postmedial line and subtermen of forewing. This species is similar to

wingspan and the rounded postmedial line without costal pro-jection of forewing. The male genitalia can be diagnosed by the short uncus, with hairy socii, the long tegumen twice to the tegumen in length, the long triangular saccus, the slender membranous valva with a strong spine-like harpe and slender aedeagus with a long spinular cornutus. The male genitalia are similar to those of
, but can be distinguished by the shape of harpe that is spine-like, distally dilated valve and the rod-shaped cornutus of vesica. The female genitalia can be distinguished by the simple sterigma, the long ductus bursae and a large ovate corpus bursae with a lip-shaped sig-num. The female genitalia are similar to those of
, but can be distinguished by the long ductus bursae with anteriorly twised.
Description (Fig.1 ).
Wingspan 20-21 mm. Antennae in male bipectinate; frons broad, trapezoidal, mixed with yellowish white and dark ochreous scales; labial palpi long, almost twice the eye diameter, projected forward, 2nd segment dis-tally dilated. Body and legs covered with whitish scales. Forewing ground color light grayish, costa basal part covered with blackish scales; postmedial line blackish, medially slightly projected outward; termen dark brownish with an undulating blackish line. Hindwing ground color light grayish, paler at basal part.
Male abdomen and genitalia (Fig.2 A-C):
Eighth tergite posteriorly sharp edges. Uncus short, slender, basally tapering; socii hairy; tegumen long, twice the length of vinculum; juxta simple with a thin sclerotized line; saccus long, triangular.Valva long, distally expanded; costa slender, weakly sclero-tized; sacculus slender with a strong spine-like harpe. Aedea-gus slim; vesica long, tubular with a long rod-like cornutus.
Papillae anales simple, roudned. Anterior apophyses long, twice of the posterior apophyses. Antrum U-shaped and membranous. Ductus bursae long, narrow, twisted anteriorly. Corpus bursa large, ovate, membranous,with a lip-shaped signum (Holloway, 2003).

I would like to thank Mr. Jeong-Seop An and Sang-Hyun Na for aiding in collecting moths. This study was supported by the project on the survey and excavation of Korean indigenous species of the National Institute of Biological Resources (NIBR) under the Ministry of Environment, Korea.
