An yponomeutid species, Saridoscelis kodamai Moriuti, is recorded from Korea and mainland China for the first time. Saridoscelinae are first recorded in the Korean fauna. Photos of external and genital features are provided for S. kodamai. Occurrence of S. kodamai in Korea is discussed in relation with the flight time and the distribution of their host plants.

    Saridoscelinae were originally proposed by Moriuti (1977) as a tribe of Yponomeutinae (now Yponomeutidae) and later elevated to subfamily status (Kyrki, 1990). Moriuti (1977) defined the Saridoscelinae as monogeneric with Saridoscelis, followed by Dugdale et al. (1998) who proposed three synapomorphies for the subfamily: a unique modification of the male 8th abdominal sternite, the presence of fringed sensillae on the socii of the male genitalia, and the presence of three branches in the median vein of the hindwing. Sohn et al. (2013) found that a previouslyunsettled genus, Eucalantica Busck, 1904, belongs to Saridoscelinae. This expansion of Saridoscelinae requires the new synapomorphies for the subfamily, whose monophyly was strongly supported with only genetic data (Sohn et al., 2013).

    SaridoscelisMeyrick, 1894, the type genus of Saridoscelinae, includes four species occurring in East Asia and India (Lewis and Sohn, 2015). Another saridosceline genus, Eucalantica, comprises seven species distributed exclusively in the New World (Sohn and Nishida, 2011). Host records are only available for four species of Saridoscelis and Eucalantica, all of which are associated with Ericaceae. Saridoscelis sphenias Meyrick is regarded as a pest on cultivated rabbiteye blueberries (Vaccinium virgatum Aiton) in China (Yu et al., 2012).

    Here, the subfamily Saridoscelinae and Saridoscelis kodamai Moriuti in Korea and mainland China are reported for the first time and the distribution of Saridoscelis in East Asia is discussed.

    Materials and Methods

    Specimens were obtained from the following institutional collections.

    IZCAS: Institute of Zoology, Chinese Academy of Sciences, Beijing, China.

    MPNU: Department of Environmental Education, Mokpo National University, Muan, Republic of Korea.

    USNM: United States National Museum of Natural History, Washington, DC, USA.

    Dissections of the genitalia were prepared following Clarke (1941), except that chlorazol black was used as a staining agent. Terms for genitalia follow Klots (1970). Terms for external features follow Moriuti (1977). The ‘GSN’ in the specimen data stands for ‘genitalia slide number.’

    Taxonomic accounts

    Yponomeutidae 집나방과

    Saridoscelinae Moriuti 1977 상제집나방아과 (신칭)

    SaridoscelisMeyrick, 1894

    SaridoscelisMeyrick, 1894: 28. Type species: Saridoscelis spheniasMeyrick, 1894.

    Diagnosis. This genus is similar to Thecobathra and Niphonympha, with both belonging to Niphonymphini of Yponomeutinae; however, it differs in having straight median and subterminal streaks convergent to the apex on the forewing; a socius with fringed sensillae in the male genitalia; and the male sternum VII modified as a sclerite covering saccus.

    Distribution. East Asia and India. Robinson et al. (1994) mentioned at least nine undescribed congeners from Southeast Asia.

    Host plants. Known in only two species (S. kodamai and S. sphenias), all belonging to Ericaceae.

    Saridoscelis kodamaiMoriuti, 1961 상제집나방 (신칭)

    Saridoscelis kodamaiMoriuti, 1961: 65. Type locality: Japan - Honshu, Kii Peninsula, Mt. Natisan.

    Description (Figs. 1-2). Head white; labial palpus white, intermixed with dark brown scales. Thorax white. Forewing length 7.1 mm, white; longitudinal subcostal line grayish brown, straight; median line starting at basal 1/3 of dorsum, running towards apex, with anterior half as black line and posterior half as oblique, narrow-triangular patch, grayish brown inside; subterminal line straight, converged to median line, juxtaposed with pale grayish brown shades outward; two grayish brown costal bars converged to apex; fringe white, suffused with dark grayish brown terminally. Hindwing grayish brown, paler to base; fringe grayish brown. Male genitalia (Fig. 3) with uncal process digitate, 2/3 as long as socius; socius usually with five or six fringed plates; valva broadest nearly at middle, acuminate apically, with small, setose hump near base; saccus elongate, as long as valva, bulbous apically; phallus bent at basal 1/4, broadened in distal 1/3, with two spinulate cornutal areas. See Moriuti (1961) for the female genitalia.

    Currently, Saridoscelis comprise four species, S. kodamai Moriuti and S. synodias Meyrick from East Asia, S. nudata Meyrick from India, and S. sphenias Meyrick occurring across Oriental and Palearctic regions. Among two East Asian species, Saridoscelis kodamai has been recorded from Japan and Far Eastern Russia, showing rather broad distribution. Our record of S. kodamai from Korea is not surprising based on its distribution in the neighboring countries, but also leaves two puzzling aspects. Our Korean specimen of S. kodamai was collected in March, much earlier than its usual flight season of May to July in Japan (Moriuti, 1977). This rejects the possibility that our specimen is due to an accidental introduction from Japan. Larval host records of S. kodamai include two ericacean plants that do not naturally occur in Korea. Of the two host plants, Pieris japonica occurs in Japan, China, and Taiwan, and its relative, P. nana, occurs in the Russian Far East. The other, Leucothoe grayana, is endemic to Japan. This host plant information only explained the distribution of S. kodamai from Japan, China and Russia, but not from Korea. The collecting site of our specimen, Mt. Dalmasan, is located in the southern part of the Korean Peninsula. There have been only two species of Ericaceae, Rhododendron mucronulatum Turcz. and R. yedoensis var. poukhanense (H. Lev.) M. Sugim. ex T. Yamaz., recorded from this mountain area (Im and Hong, 2005). Additionally, no trophic association of S. kodamai with Rhododendron has been identified to date. The larvae of S. kodamai most likely feed on Vaccinium bracteatum Thunb. in Korea. This shrub species spreads broadly in Haenam County, although it has not been recorded from Mt. Dalmasan. It is known that S. sphenias feeds on V. bracteatum in Japan (Moriuti, 1961). Another possible, albeit less likely, food source for S. kodamai in Korea is Pieris japonica, which is uncommonly cultivated as a garden plant in the southern provinces.


    We are indebted to Dr. Chun-Sheng Wu (Chinese Academy of Sciences, Beijing) in translating the Chinese label. We would like to thank Dr. Donald Davis (United States National Museum of Natural History, Washington, DC) for allowing the first author to loan specimens under his responsibility. This work was supported from the Korea Research Fellowship program funded by the Ministry of Science, ICT and Future Planning through National Research Foundation of Korea (2015035581).
