Junggon Kim and Sunghoon Jung Chungnam National University The Flora and Fauna of Korea logo was designed to represent six major target groups of the project including vertebrates, invertebrates, , algae, fungi, and bacteria. PREFACE

Biological resources include all organisms and their genetic characteristics. Conservation and utiliza- tion of these resources have the capacity to improve human life and to enhance the world. Therefore it is required that the practical and potential values of these organisms are conserved and used wisely. The first step towards this goal is to document our biological diversity and to investigate them in detail. Biological resources increase the competitiveness of a nation through their use as fundamental resources for making highly valued products, such as new lines of cultivar, materials, and drugs. Many countries in the world are responsible for preserving their and using the sustainable ways. The Ministry of Environment (MOE) of Korea has established “CBD-CHM Korea” to share of infor- mation of biodiversity. Each nation in the world is investigating and clearing information of native species within its territory. The National Institute of Biological Resources (NIBR) of MOE has published the ‘Flora and Fauna of Korea’ since 2009 to manage biological resources in comprehensive ways and to enhance national compe­ titiveness by building up the foundation for the sovereignty rights over biological resources. Professional research groups, consisting of professors and other taxonomic experts, have systematically examined 15,545 species of vascular plants, and other organisms over the past 10 years and have published their find- ings in 191 volumes in Korean and 196 volumes in English, and two volumes of monographs covering 216 species of invertebrates. This year, 21 volumes of the Flora and Fauna of Korea in both Korean and English versions including 704 species of vascular plants, invertebrates and insects are additionally published. The NIBR will continue to publish and research of flora and fauna of Korea that contribute conserva- tion and sustainable use of biological resources. Finally, I would like to express my sincere appreciation to authors who made efforts in writing the manuscripts of the Flora and Fauna of Korea.

7 INSECT FAUNA OF KOREA Mirinae II

INTRODUCTION

The subfamily Mirinae (Hemiptera: Heteroptera: Cimicomorpha) is the largest group in the family Miri- dae, with more than 4,100 species in the world (Schwartz, 2008; Schuh, 2002-2013). In Korea, this group comprises approximately a sixth of the total number of heteropteran species (Lee et al., 2013). Most mirine species are phytophagous and closely related with various plants, such as herbs and trees (Kerzhner, 1988a). Mirinae also contains zoophagous and zoophytophagous species, with a variety of mor- phological characters adapted to prey types or habitats. Some mirines species, such as and A. spinolae, are major insect pests of various and crops (e.g., grape, persimmon, and cotton) in Korea and adjacent countries ( and China) (Lee et al., 2002; Pan et al., 2013). However, some of the predatory Mirinae species have considerable potential as biological control agents. Predators in the sis- ter-group Bryocorinae (e.g., Nesidiocoris tenuis, Macrolophus pygmaeus, and M. melanotoma) have been used in greenhouses and fields to control whiteflies, , and mites (Evangelou et al., 2013). Therefore, Mirinae is an important group economically, since it contains insect pests and potential biological control agents. A total of 117 species and 41 genera have been recorded from the Korean Peninsula to date (Kwon et al., 2001; Seong & Lee, 2007; Cho et al., 2008; Kim et al., 2015; Kim & Jung, 2016a; Kim et al., 2017; Kim & Jung, 2018a) however, there have been limited taxonomic studies on Korean Mirinae. Most Korean species were studied by Josifov and Kerzhner in the late 1990s (Josifov & Kerzhener, 1972; Josifov, 1978, 1985). This book is the second volume continuously corresponding to Mirinae I, containing remaining species. The first volume, Mirinae I contains major groups (e.g., Adelphocoris and Apolygus) in Mirinae for provid- ing information of some important species (e.g., A. lucorum, A. spinolae). In this book, 73 species of the subfamily Mirinae are addressed from the Korean Peninsula. The genus Phytocoris is excluded in this book, because the special volume for Phytocoris is separately published. Morphological data, including descrip- tion of male genitalia and diagnosis, and biological data such as host plant of each species are presented with photographs and illustrations.

8 MATERIALS AND METHODS

MATERIALS AND METHODS

Samples were collected using nets and several traps (e.g., light trap and malaise trap) all over Korea, and were examined using specimens deposited in Institutions listed below. Photographs of specimens were taken by Leica DMC 2900 camera combined with Leica M165C stereomicroscope. Measurements were taken us- ing software program (LAS Interactive Measurements) on the same stereomicroscope. All measurements are given in millimeters (mm). To observe male and female genitalia, abdomen of each specimen was detached, and then soaked and heated in 10% KOH solution at 70°C for 5 minutes to 2 hours until it became transpar- ent. After placing it in distilled water, it was dissected to examine parameres and endosoma for male, and sclerotized ring and posterior wall for female. Terminology mainly follows Yasunaga (1991) for male and Yasunaga & Schwartz (2007) for female genitalic structures. In the description, abbreviations for male and female genitalia are as follows:

Male genitalia ls - lateral sclerite; ms - median sclerite; ns - needle shaped spicule; sls - sublateral sclerite; vsc - ventral sclerite and ws - wing shaped sclerite

Female Genitalia sr - sclerotized ring; irl - interramal lobe and irs - interramal sclerite

Abbreviations for depositories of examined specimens and collection sites are also as follows:

7. ‌Apolygus nigrovirens (Kerzhner, 1988)

Lygocoris (Apolygus) nigrovirens Kerzhner, 1988b: 21; Yasunaga, 1992b:15.

Host: Thermopsis lupinoides (Fabaceae) (Kerzhner, 1988b; Yasunaga, 1992b).

Distribution: Japan, China, Russia.

Region: Palaearctic Region.

Remarks: This species is very similar to its congener, A. spinolae, in particular in case of dark individu- als. In addition, even though the male genitalia is examined, it is hard to distinguish them (Kerzhner, 1988b). Kerzhner (1988b) indicated that this species was found on Thermopsis lupinoides (Northeastern goldenban- ner; Fabaceae), a plant inhabiting on sandy sea coast, a host plant and a habitat not frequent by the polypha- gous species A. spinolae. However, Kwon et al. (2001) recorded this species in their catalogue with numbers of specimens. They also indicated that its host plant was not T. lupinoides but Solanum tuberosum (Solana- ceae) distributed in all regions in Korea. Seong (2008) indicated that most specimens determined as A. ni- grovirens by Dr. Kwon were mixed with three species A. lucorum, A. spinolae and A. watajii. Therefore, we propose the record of this species from Korean fauna to be deleted until voucher specimens are available.
