Two species of the genus Coccura Šulc, 1908 from Korea are reviewed. Coccura convexa Borchsenius, 1949 and C. suwakoensis (Kuwana and Toyoda, 1915) were recorded from North Korea by the report of Danzig (1980). Although Kwon et al. (2003) described Coccura comari (Kunow, 1880) from South Korea, we found that this species was misidentification of C. suwakoensis. In this study, we suggest that Coccura comari (Kunow, 1880) is to be excluded from the Korean fauna. The occurrence of C. suwakoensis is also recorded from South Korea for the first time, based on the additional populations which were heavily infested on the Chinese fingetree, Chionanthus retusus Lindley and Paxton. A key to the species of Coccura known from Korea is provided with diagnoses and photographs.

The Lucid technology as an interactive fully illustrated identification tool, has developed and assisted in the diagnosis of agricultural and quarantine pests and invasive organisms over the past years. In this study, lepidopterans specifically relating to quarantine pests were selected for a lucid key development based on the border inspection data from 1996 to 2016 in South Korea. They belong to four families: Sphingidae, Noctuidae, Pyralidae and Crambidae, and also categorize into the three groups: regulated, potential regulated and non-quarantine pests. The key includes diagnostic characters from head, thorax, fore- and hind-wings for each species examined.

Nomenclatural changes are provided for Sorbus-feeding Cacopsylla moiwasana (Kuwayama, 1908) species group. Thirteen Palaearctic Cacopsylla species have been recorded from Sorbus L. (Rosaceae), and of these, seven species restricted to East Asia. Among the East Asian species, four Japanese species, i.e. C. elegans Inoue, 2004, C. jezoensis (Miyatake, 1963), C. midoriae (Miyatake, 1963) and C. moiwasana (Kuwayama, 1908), assigned to C. moiwasana species group. Above the latter three species very similar to each other, allopatrically distributed, and all or some of them could be synonymous. The present investigation of the type material resulted in confirmation that Psylla jezoensis and P. midoriae should be treated as junior synonym of P. moiwasana. The following synonyms are proposed: Cacopsylla moiwasana (Kuwayama, 1908) = Psylla jezoensis Miyatake, 1963, syn. nov., Psylla midoriae Miyatake, 1963, syn. nov. The species are newly recorded from Korea.

Mirinae is the most diverse subfamily within the family Miridae (Hemiptera: Heteroptera), and includes more than 4,000 species. In Korea, mirids were first recorded from Jeju Island in the mid-1960s. Since that study, numerous plant bug species from the Korean peninsula have been newly recognized and described. Previously, 101 species of Mirini were recorded from Korean peninsula. In this study, we provide an additional information of Mirini in Korea with a description of new species and new records.

Genus Trissolcus are considered as most effective natural enemy for control Pentatomid pests. Trissolcus japonicus (Ashmead) is native egg parasitoid of the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) in Palearctic region. Nevertheless, identification of Palearctic Trissolcus species are still controversial because of morphological homogeneity such as Trissolcus semistriatus (Nees, 1834) and Trissolcus Kozlovi Ryakhovskii, 1975. This study reassessed Korean Trissolcus species diversity and provided DNA barcoding data using mitochondrial cytochrome c oxidase subunit I (COI) gene for 11 Korean Trissolcus species.

Family Nitidulidae is the second largest family in Cucujoidea which includes ten subfamilies. Because of their morphological and biological diversity, the phylogenetic relationship within Nitidulidae is one of the most debated topics among Cucujoidea phylogeny and yet, is still open to many questions. To recover the internal relationship of Nitidulidae, we performed ML and BI analyses that targeted on five gene regions (COI, 28s, CAD, H3, Wingless) for 73 taxa. We include 67 ingroups containing nine of the ten currently recognized subfamilies of Nitidulidae and 6 outgroups. The phylogenetic results suggest followings i) Subfamilial status of Prometopinae is reconfirmed; ii) Epuraeinae is paraphyletic with inclusion of Calonecrinae; iii) Nitidulinae is paraphyletic with inclusion of Meligethinae and Cillaeinae. In addition, the generic relationships within Nitidulinae and the evolutionary history of their feeding behaviors are also briefly discussed.

Evolutionary relationship between ovipositior and oviposition behaviour in insect is an intriguing yet poorly understood topic. Gigantic member of phytophagan, the subfamily Cerambycinae provide us a unique opportunity to understand the topic because they have diversified but specialized host plants, oviposition strategies and ovipositors. The evolutionary pathway of these traits is totally unknown because no robust internal phylogeny of Cerambycinae has been studied. Here we construct a multi-locus phylogeny of Cerambycinae (134 taxa, 9 gene regions, 5211bp) focusing on wide range of oviposition site, host plant and ovipositor length. Ancestral state reconstruction analyses show some general trends in cerambycine evolution: i) host plant use evolved from stressed broad leaved trees to conifers and herbaceus plants; ii) oviposition site evolved from bark crevice to wood fissure or plant surface; iii) extremely shortened and elongated ovipositor independently evolved at least four times, respectively. Correlated evolution test show that ovipositor length and oviposition strategy evolved with very strong correlation, while any of other two traits did. This study unveils the complex evolutionary history of ovipositor, oviposition site, host plant use and their correlation within Cerambycinae for the first time.

Gelechioidea is the superfamily that contains diverse groups comprising over 16,000 species in worldwide. It was estimated that only 25% of the species diversity of the Gelechioidea has been described. In this study, DNA barcoding was assessed based on cytochrome c oxidase subunit I (COI) for the 154 morphologically identified Korean gelechioids. The results of three molecular species delimitation methods were consistent for 72% with their morphological identifications. Based on molecular operational taxonomic unit (MOTU) estimation, we discussed on discordant groups including barcode sharing pairs and cryptic species.

The confused taxonomy of the east Palaearctic pear psyllids, serious pests on cultivated pear, is reviewed. Fifty-sixnominal species have been reported from Pyrus, 25 of which we consider valid and ten as not being associated withPyrus. Our taxonomic revision suggests that, in Korea, four Cacopsylla species develop on pear. Three species occuralso in Japan. New synonyms are suggested and seasonal dimorphism are critically discussed.Key words : Psyllidae, Cacopsylla, taxonomy, host plant, Pyrus, Rosaceae, Manchrian pear, Asian pear, European pear, China,Japan, South Korea, Russian Far East

Since the citrus flatid planthopper, Metcalfa pruinosa (Say, 1830), was firstly reported from Korea, they are rapidlyspreading on a national scale and causing serious damages on many valuable crops. Until now, Gangwon Province israrely spread except few south-west area, Wonju and Hoengseong. But after recent investigation in Gangwon Province,its additional distributions are verified in several regions. Also, we analyzed the mitochondrial cytochrome c oxidase subunit-I(COI) gene by neighbor joining method to identify whether populations of M. pruinosa in Gangwon Province show samegenetic composition with existing populations.

The genus Dirrhagofarsus Fleutiaux, 1935 is firstly reported from Korea with three species, Dirrhagofarsus lewisi (Fleutiaux,1900), D. modestus (Fleutiaux, 1923), and D. unicolor (Hismatsu, 1960). Among them, D. unicolor was described asa ‘form(=f.)’ of D. modestus by Hismatsu (1960). In this study, we re-establish the status of this species as proper species,Dirrhagofarsus unicolor. We provided a key to Korean Dirrhagofarsus species, diagnoses, and photographs for each species.

Trophic associations of lepidopteran larvae have been formed from a long period of evolution. The larva of Oecophoridaecan keep being concealed with several strategies. They may be sheltered within a web or hidden under bark or deadwood, or inside leaves rolled by them. Sometimes they bore stem or trunk or burrow under bark or hide in soil. In addition,they can also be found in very diverse and specialized microhabitats. This study was to assess the ancestral characterstate of microhabitat and larva sheltering strategy within the phylogenetic relationship of Oecophoridae to understand theirevolutionary transition and the adaptation of larva to microhabitats using sheltering strategies. Also, it is to investigatethe historical biogeography and evolution of the family Oecophoridae and related higher taxa for understanding their globalradiation and distribution.
