A Korean translation of this issue is simultaneously published for Korean speaking readers. This English version therefore should be regarded as an original publication that has nomenclatural priority.

The Flora and Fauna of Korea logo was designed to represent six major target groups of the project including vertebrates, invertebrates, insects, algae, fungi, and bacteria. The book cover and the logo were designed by Jee-Yeon Koo. Chlorococcales: 1

Preface

The biological resources include all the composition of organisms and genetic resources which possess the practical and potential values essential to human live. Biological resources will be firmed competition of the nation because they will be used as fundamental sources to make highly valued products such as new lines or varieties, new material, and drugs. As the Nagoya Protocol th was adopted in 2010 and entered into force in the 12 Conference of Parties of the Convention on

Biological Diversity (CBD) in 2014, it is expected that the competition to get biological resources will be much intensive under the rapidly changed circumstance on the access and benefic sharing of the genetic resources (ABS). Therefore, each nation is investigating and clearing information of native species within its territory in order to secure its sovereignty rights over biological resources. The National Institute of Biological Resources of the Ministry of Environment has been publishing the ‘Flora and Fauna of Korea’ since 2006 to manage biological resources in comprehensive ways and to enhance national competitiveness by building up the foundation for the sovereignty over biological resources. Professional research groups consisting of professors and related experts of taxonomy examined systematically a total of 12,631 species for the past eight years to publish 151 volumes in both Korean and English versions, and two volumes of World Monograph cover- ing 216 species. This year, 11 volumes of the Flora and Fauna of Korea each in Korean and English versions including 517 species of invertebrates, insects, vascular plants, algae and fungi are addi- tionally published. Flora and Fauna of Korea were the first professional records to describe all the species of the nation in a comprehensive way, and they would contribute to level up the taxonomic capacity. Furthermore, publication of flora and fauna through identification of native species and investigation of national biota would be helpful to declare sovereignty rights over our native biological resources, be used as positive proof, and be utilized to provide the basic information of biological resources for industrial application. The National Institute of Biological Resources of the Ministry of Environment will continue to accelerate the project of the publication of the ‘Flora and Fauna of Korea’. Personally I would like to express my sincere appreciation for Professor Jong-Wook Lee, Ms. Su-Bin Lee and Dr. Jin-Kyung Choi of Yeungnam University who have continuously made a lot of efforts to publish an excellent version of Korean fauna.

Introduction

Family Argidae is the second largest family among Symphyta, Hymenoptera and about 815 species belonging to 58 genera have been recorded as of the end of 2013. In Eastern Asia, 50 species and six genera of the family have been recorded from Japan (Shinohara, 2013; Hara and Shinohara,

2014). About 169 species and 16 genera have been recorded from China (Wei et al., 2006; Wei, 2008; Zhang and Wei, 2008; Yan et al., 2008; Wei and Niu, 2010). The fauna of Argidae in Korea has been poorly investigated and only 21 species and two genera have been recorded (Shinohara et al., 2009; Paek et al., 2010). In Northeastern Asia, only two genera of Arginae have been recorded: Arge Schrank, 1802 and Spinarge Wei, 1998. Arge Schrank is the largest and most complicated genus in Argidae. More than 350 species have been recognized as of 2013. Genus Arge is mainly distributed in the Holarctic and

Ethiopian regions of the world (Taeger et al., 2010). About 120 species have been recorded from

China (Wei, 1997; Wei and Wen, 1997; Wei et al., 2006; Nie and Wei, 2008), 30 species from Japan

(Shinohara, 2013; Hara and Shinohara, 2014) and 20 species from South Korea (Shinohara et al., 2009; Paek et al., 2010). Spinarge Wei is closely related to Arge and about 11 species have been described from eastern Asia. Sterictiphora Billberg, 1820 is the fifth largest genus of Argidae and about 40 species have been described (Taeger et al., 2010). Among them, 20 species have been reported from the East Palaearctic region, and most of them were described from Japan (Takeuchi, 1939; Togashi, 1968) and China (Wen et al., 1998). A few species were recorded from the Far East of Russia (Zhelochovtsev, 1939; Mal- aise, 1944). The genus was very poorly studied in Korea and only one species, Sterictiphora tanoi, was reported (Togashi, 1997). However, the survey of the Korean sawfly fauna in progress shows that species of Sterictiphora are probably not rare in Korea. Yasumatsua Togashi, 1970 is a very small and unique genus of the subfamily Sterictiphorinae.

Two species have been described, one from Japan (Togashi, 1970) and another one from Taiwan,

China (Togashi, 1990). The finding of the rare genus from Korea shows that there may be more genera and species of Argidae in Korea. Aproceros Malaise, 1931 is a small genus of Sterictiphorinae and is endemic to northeastern Asia.

About 10 species have been described in the world (Taeger et al., 2010). One species of the genus has been recorded from Korea in this book. But an unrecorded species, A. leuocopoda Takeuchi, 1939 which is an important pest of Ulmus spp. And also an invasive pest for Europe is expected to be collected in future from Korea.

Historical review of the family Argidae in Korea The taxonomic study of the Korean Argidae was initiated by Konow who reported the first two species of Korean Argidae: Arge anceps Radoszkowsky, 1889 (now a synonym of Arge ustulata (Linné,

1758)) and Arge assimilis (Radoszkowsky, 1889) (now a synonym of Arge pagana (Panzer, 1797)). In the following about twenty years, the Korean Argidae fauna received very little attention. Takeu- chi (1927, 1932, 1936) added Arge nipponensis Rohwer, 1910, Arge captiva rufoscutellata Takeuchi,

1927, Arge hasegawae Takeuchi, 1927, Arge zonalis Matsumura, 1911, Arge mali (Uchiyama, 1906) and,

Arge fuscipes (Fallén, 1808). After two years, Doi (1938) added one species, Arge suspicax Konow,

1908. Four species, Arge coeruleipennis Retzius, 1783 (now a synonym of Arge enodis (Linné, 1767)),

Arge coerulescens Geoffroy in Fourcroy, 1785 (now a synonym of Arge gracilicornis (Klug, 1814)), Arge 6 Insect Fauna of Korea·Sawfly I

metallica Klug, 1834 (now transferred to Spinarge) and Arge dimidiata (Fallén, 1808), were recorded in Takeuchi (1939). For the first time as the Korean taxonomist, Kim (1963) revised Korean Argidae and 15 species including three unrecorded species, Arge flavomixta (André, 1881), Arge jonasi (W.F.

Kirby, 1882) and Arge similis (Snellen van Vollenhoven, 1860) were reported. After three years, Kim

(1970) added Arge cyanocrocea (Forster, 1771) and Arge fulvicornis (Mocsáry, 1909) (now transferred to Spinarge). Zombori (1971, 1974, 1978) recorded three species, Arge clavicornis (Fabricius, 1781),

Arge nigrovaginata Malaise, 1931, Arge nigripes alpina (Konow, 1884). One additional species, Ster- ictiphora tanoi Togashi, 1997, was described from Korea by Togashi (1997). Paek et al. (2010) listed

19 species of the Family Argidae from Korea. Recently, Lee et al. (2015) revised Sterictiphora from

South Korea and reported 5 species including four undescribed species. Wei et al. (2015) reviewed the Arginae of South Korea and recorded 2 genera and 30 species including three new species. The current total 40 species in 5 genera of Argidae are described from Korea in this study. Materials and Methods 7

Materials and Methods

We examined more than 5,000 specimens of Argidae from Korea and borrowed specimens deposited in the following institutions: Department of Biological Science, Andong National University, Korea; Department of Biology, Changwon National University, Korea; Department of Life Science, Daejeon University, Korea; Department of Biology, Gyeongsang National University, Korea; De- partment of Biology, Korea University, Korea; Department of Biology, Sungshin Women’s Univer- sity, Korea; Faculty of Biological Science, Wonkwang University, Korea; Department of Biology, Yeungnam University, Korea; Department of Life Science, Yonsei University, Korea; Department of Environmental Engineering Education, Mokpo National University, Korea; Daehan Specimen Insti- tute, Korea; Faculty of Science, Hokkaido University, Japan (HU); Deutsches Entomologisches Insti- tut im ZALF, Müncheberg, Germany (DEI).

All photographs were obtained using an AxioCam MRc5 camera attached to a stereo microscope (Zeiss SteREO Discovery. V20; Carl Zeiss, Göttingen, Germany), processed using Axio Vision SE64 software (Carl Zeiss), and optimized with a Delta imaging system (i-solution; IMT i-Solution Inc., Vancouver, Canada). All the materials examined are deposited in the Department of Biology, Yeun- gnam University in Korea.
