The genus Perixera Meyrick was designated based on Peri-xera prionodes Meyrick as the type species and comprises about 80 species mostly from Indo-Australian region (Hollo-way, 1997; Scoble, 1999). The species of Perixera show vari-able wing pattern and relatively delicate fascination and they are distinguished from Anisodes Guenee (a junior synonym of Cyclophora Hubner) by a pair of coremata on the fourth sternite, the coremata between the eighth sternite and the genitalia, a convolute aedeagus apex, the convolution involv-ing the insertion of the ductus ejaculatorius, broad uncus with bifid or serrate, a broad and well developed costal process of valva, often bilaterally asymmetric, the weak or vestigial saccular process and shortening of the hind tibia (Holloway, 1997).

The present study describes a sterrhine species, Perixera punctata (Warren), for the first time in Korea. Two specimens were collected at the southern slope of Mt. Halla-san, Jeju-do. Examination of adults including the male and female gen-italia refers to Scoble (1992). Abbreviations are as follows: TL, type locality; JJ, Province Jeju-do.

Diagnosis. This species can be distinguished by the bipecti-nate male antennae with long rami, broad, trapezoidal, whit-ish frons, long and laterally reddish labial palpi, reddish fore-leg and midlegs, whitish body, light brownish forewings with blackish discal dot, a relatively large dark grayish dot on the subcosta between the postmedian and subtermen and black-ish dots along the postmedial line and light brownish hind-wings with a large dark brownish discal dot and blackish un-dulating postmedial line. In Korea, this species is externally similar to Organopoda carnearia (Walker), but can be distin-guished based on the bipectinate male antennae, light brown-ish and shorter wingspan and the dark brownish dot on the

subcostal of the forewing. The male genitalia can be distin-guished by the missing uncus, short tegumen and long slen-der valva with two arm-shaped medially bent costal process-es, one digitate process apically expanded and another pro-cess apically hairy. The female genitalia can be distinguish-ed by the minute anterior apophyses, long posterior apophy-ses, narrow antrum, long and medially twisted ductus bursae with a colliculum, and large, ovate corpus bursae of which the inner wall is covered with minute dots at larger areas.

Description (Fig. 1). Wingspan 19-21 mm. Antennae in male bipectinate with long rami, female filiform; frons broad, tra-pezoidal, covered with whitish scales; labial palpi long, almost three times of eye diameter, projected forward, laterally red-dish. Body covered with whitish scales. Legs reddish or dark ochreous and white mixed scales. Forewing ground color light brown; basal line light blackish, projected at middle; discal dot blackish; postmedial line dark grayish, undulating; a relatively large dark grayish dot on subcosta between post-median and subtermen; subtermen with blackish dots along postmedian; termen with black dots along terminal line; sin-gle areole. Hindwing ground color light brown; basal line blackish, weakly appearing; discal dot large dark brownish; postmedial line blackish, undulating; termen with a blackish undulating terminal line.

Male genitalia (Fig. 2A, B): Abdominal segment A4 and A8 simple, broad without modification. Uncus absent; tegumen triangular, short, about one third of vinculum; transtilla sim-ple, membranous; juxta broad; saccus broad, bridge-shaped. Valva long, slender; costa with two arm-shaped process, a ventral process medially bent and apically strongly expanded, a dorsal process medially bent and apically hairy; sacculus short, weakly sclerotized, dorsal margin with minute hairs. Aedeagus slender, distally sclerotized; vesica membranous, tubular; cornutus a minute process.

Female genitalia (Fig. 2C): Papillae anales projected. An-terior apophyses minute, posterior apophyses very long. An-trum narrow and membranous; ductus bursae long, narrow, twisted medially, colliculum present; corpus bursae large, ovate, membranous, inner wall largely covered with minute dots.

Distribution. Korea, China (Hong Kong), Mindanao, Borneo, Sulawesi, New Guinea, and Queensland.
