An investigation on the habitation of Callipogon relictus Semenov was carried out in Gwangneung forest, Korea and Ussurisky nature reserve, Russia. During the investigation period (2007–2018), a total of 25 emergence holes, 10 pupal chambers, 10 adults, and two larvae of C. relictus were identified in Gwangneung forest. In this presentation, we provide biological information on habitation of C. relictus in Gwangneung forest by comparison and combination of survey results in Ussurisky nature reserve, in 2015 and 2018. In addition, the distribution range of C. relictus is also reviewed in the Korean Peninsula with a new location.

Host relationships between insects and plants are one of the major factor driving evolutionary diversification within terrestrial ecosystems. Beetles (Coleoptera) are the most diverse and species-rich group of insects, and a robust, time-calibrated phylogeny is fundamental to understanding macroevolutionary processes that underlie their diversity. Recently, many studies have been carried out about the relationships among those taxa according to the attention on co-evolution of phytophagous insects and their hosts, however, most of them focused on special taxa (family or genus level) of insects. In this presentation, we especially reviewed current trends of studies on interactions between coleopteran insects and host plant in the world and Korea for proposals of future studies.

In the present study, we make a first report on the complete mitochondrial DNA genome of Leptaulax koreanus, a Korean endemic species, in Passalidae. The mitogenome is 18,730 base pairs with 13 protein coding genes (PCGs), 22 tRNAs, two rRNAs and a 4240 bp long AT-rich region. The overall base composition is 78.4% AT and 21.6% GC. The maximum likelihood analysis inferred that L. koreanus is a sister to other Scarabaeoidea species. The phylogeny suggested that L. koreanus is the basal group of Scarabaeoidea.

2016년도에 조사를 수행한 경상북도 내 위치한 산림유전자원보호구역 3개 지역(봉화･영주･울진)의 곤충 군집 변화를 확인하기 위하여 5월에서 9월까지 함정 트랩(pitfall trap)을 이용하여 5회씩 3반복하여 각각 상대적으로 비교 하였다. 채집된 딱정벌레류는 딱정벌레과 등 22과 141종 2,415개체가 확인 되었으며, MRPP (Multi-response Permutation procedures)분석 결과 서식지간의 군집구조차이가 있음을 확인 하였고(p < 0.001), Bray-cutis 분석결과 군집간의 차이와 함께 신갈나무 군락이 보행성 딱정벌레류의 종 풍부도에 큰 영향을 주는 것으로 나타났고 소나무군락 은 비교적 낮은 영향을 받았다. 식생유형에 대한 지표종 분석결과 신갈나무 군락에서 붉은칠납작먼지벌레(Synuchus cycloderus Bates, 1873)를 포함한 4종, 자작나무 군락에서는 노랑털검정반날개(Ocypus weisei Harold, 1877)를 포함한 3종, 소나무 군락에서는 홍딱지반날개(Platydracus brevicornis Motschulsky, 1862)를 포함한 3종의 지표종 변화를 확인 하였다.

While working on beetles collected by using flight interception trap, we found specimens possessing similar characters with salpingidine genus Lissodema Curtis. After detailed examination of the specimens and comparison with other Lissodema species, we concluded that these specimens represent a new species of the genus. The genus Lissodema was first proposed by Curtis based on Lissodema heyana Curtis and contains 19 species in the Palaearctic region. In eastern Asia, 14 and three species are recorded in Japan and Russian Far East, respectively, but no species have been reported from Korea. In this study, a description, habitus photographs and line drawings of diagnostic characters of a new species from Korea are provided.

The family Monotomidae Laporte includes about 240 species placed in 33 genera worldwide and five species in three genera have been recorded to date in the Korean Peninsula. Mimemodes Reitter contains 15 species occurring worldwide including nine Palaearctic species, of which five are recorded in Japan. In the Korean Peninsula, the genus and a single species, Mimemodes emmerichi Mader, were first recorded by Kang et al. In the present study, we report an additional Korean species of the genus, namely Mimemodes cribratus (Reitter). We provide a redescription, images of habitus and diagnostic characters of the species along with a key to Korean species of Monotomidae.

Cerambycidae, a family of Coleoptera (Insecta: Chrysomeloidea), include approximately 33,000 species from the world and 357 species are recorded from the Korean peninsula. The members of this family are regarded as insect pests because they bore inside of host plants, otherwise, some lepturine species are pollinators of flowering plants. In Korea National Arboretum (Korea Forest Service), we are carrying out investigation of cerambycids biodiversity in Korea and neighboring countries. As results, we present some results of studies on host plants of Korean Cerambycidae and further study plans in a new project, "interactions between phytophagous insects and plants including microorganisms" in Korea National Arboretum.

A taxonomic review of the Acrotona Thomson in Korea is presented. The genus is represented in Korea by 10 speciesincluding two new species, A. koreana Lee & Ahn, sp. nov. and A. rufescens Lee & Ahn, sp. nov. Two other species,A. paeksongrica Paśnik and A. suyangsani Paśnik, are synonymized under A. pseudotenera (Cameron) and A. lutulenta(Sharp), respectively, and four species, A. grata (Cameron), A. lutulenta (Sharp), A. pseudotenera (Cameron) and A. vicaria(Kraatz), are identified for the first time in South Korea. A key to the Korean species and illustrations of habitus anddiagnostic characters are provided for the new species.

A taxonomic study of Korean species of the geostibine genus Aloconota is presented. The genus is represented in Korea by seven species including five new species, A. brunnea Lee & Ahn, sp. n., A. hydrosmectoides Lee & Ahn, sp. n., A. impressa Lee & Ahn, sp. n., A. parviocularis Lee & Ahn, sp. n. and A. tuberculata Lee & Ahn, sp. n. A key to the Korean species and illustrations of diagnostic characters are provided.

The genus Paraloconota was described as a subgenus of the genus Atheta by Cameron (1939) including seven species and he noted that it is similar to Aloconota Thomson, but can be distinguished by transverse impression of abdominal tergite IV and absence of tubercle of male tergite VII. Since then, Coiffait (1982) first treated it as a genus and described a new species. Pace (1993) proposed it as a subgenus of the genus Liogluta Thomson, 1858. Later, however, he (1998) treated it as a different genus related Liogluta. Smetana (2004) followed Coiffait (1982) and Pace (1998), and listed a subgenus Paraliogluta Pace of Liogluta as a synonym of Paraloconota. Members of the Paraloconota can be distinguished from other aleocharine genera by combination of the following characters: infraorbital carina incomplete or absent; labium with ligula divided in 2 lobes at base, lateral pseudopores absent on prementum; mesoventral process reaching to half length of mesocoxae, pointed at apex; metaventrite not produced between metacoxae narrowly separated; pubescence relatively long; legs long; empodial seta distinctly longer than claw; male tergite VII without tubercle; median lobe of aedeagus narrow apically in ventral aspect. (Cameron 1939, Pace 1991) The genus Paraloconota contains 26 species with a limited distribution in the East Palaearctic and Oriental regions (Smetana 2004) and they are usually found in the long moss attached to boulders in swiftly running mountain streams (Cameron 1939). While studying on Korean Athetini, the genus Paraloconota and a new species, P. koreana sp. n., are identified for the first time in Korea. Also we found that they are in agreement with the diagnostic characters of the tribe Geostibini Seevers, 1978 presented by Elven et al. (2012). In this study we transfer from Athetini to Geostibini and provide a habitus photograph and illustrations of the diagnostic characters of Paraloconota koreana sp. n..
