Abstract

In this study, we newly found the largest Platyptilia species, P. nemoralis Zeller from Korea. Illustrations of adult and genitalia are provided with information of host plant and distribution.

초록

본 연구를 통해 한국에서 자생하는 털날개나방 중 가장 큰 종, Platyptilia nemoralis zeller가 새롭게 추가되었다. 그 성충의 외부 형질과 생식기 형질 특징이 기주식물과 분포 정보와 함께 제공되었다.

    The family Pterophoridae, commonly known as ‘Plume moth’ is easily recognized by the cleft wings. They are distributed all over the world comprising more than 1, 100 speies (Gielis, 2003).

    Among them, the genus Platyptilia Hübner is the largest genus of the Pterophoridae comprising about 110 species majority from Afrotropical and Palaearctic, less than 15 species from Australasian, Neotropical, Oriental and Nearctic Regions (Gielis, 2003). However, only one species, Platyptilia suigensis, has been reported to date in Korea (Matsumura, 1931).

    The Platyptilia is characterized by followings: i) forewing venation with radius vein I; ii) costal triangular patch at 2/3 of forewing dark brown color; iii) third lobe of hindwing bearing dense tufts (= scale-tooth); iv) male genitalia with symmetircal and lanceolate valva; v) female genitalia with horn-shaped signa.

    In this study, we newly added the species of Platyptilia, P. nemoralis, from the south part of Korea. Illustrations of adult and female genitalia were provided with information of hostplant and distribution.

    Material and methods

    This study is based on specimens deposited in the Korea National Arboretum (KNA), Pocheon, Korea. For examination, all slide vouchers of abdomen and genitalia were made by the first author and then, they were taken by digital camera, Diagnostic Instruments, Inc. 14.2 Color Mosaic attached on the microscope, Leica DM 400B at a resolution of 600 dpi. The color standard for the description of adults follows Kornerup and Wanscher (1978).

    Diagnosis (Fig. 1). This species has the largest wingspan among the Korean and Japanese Pterophoridae. It is easily distinguished by following morphological characters: i) largest sized wingspan about 34mm; ii) brownish yellow forewing ground color with dark brown costal triangular patch and terminal line near to termen iii) scale-tooth placed at 2/3 on the 3rd lobe of hindwing.

    Female genitalia (Fig. 2). Papilla anales setose. Apophyses posteriores very long, twice than the length of the eight sternum; the terminal tips gradually inflated. Apophyses anteriores very short, 1/4 length of apophyses posteriors. Lamella postvaginalis triangular-shaped with two lateral small lobes; the lobes bearing dense setose. Antrum narrow. Ductus bursae membraneous, narrow, gradually broaden towards corpus bursae. Corpus bursae circular-shaped, bearing two horn-shaped signa.

    Material examined. Three females: two females, Suncheon, Jeonlanam Prov., 28. viii. 1971, gen. slide no. 8040/S. Kim; one female, Mt. Baekwoon, Gwangyang, Jeonlanam Prov., 22. viii. 2007, gen. slide no. 8160/S. Kim.

    Hostplant.Senecio fuchsii Gmelin, S. fluviatilis Wallr., S. sarracenicus L., S. nemorensis L (Asteraceae). (Matthews and Lott, 2005).

    Distribution. Palaearctic: Korea (South: Jeolanam Prov.) (this study), Japan (Hokkaido, Honshu) (Yano, 1963), Russia (Sakalin region, Kuril Is. Primorskii region) (Sinev, 2008), Europe (Gielis, 2003).
