Review of the egg overwintering sawfly genus Apethymus Benson (Hymenoptera: Tenthredinidae: Allantinae) from South Korea

The South Korean species of the genus Apethymus Benson are studied. Here we report two species, A. kunugi Togashi, 2005, and A. sidorenkoi Sundukov, 2010, new to South Korea. The male of A. kolthoffi (Forsius, 1927) is described in detail. A key to the South Korean species, diagnoses with brief variations, photographs of the diagnostic characters, distributions and recorded hosts for each species are provided.     

Taxonomic review of the genus Orius (Heteroptera: Anthocoridae) in the Korean Peninsula

A total of five species the genus Orius are revised from the Korean Peninsula, containing four native species, O. minutus (Linnaeus 1758), O. sauteri (Poppius 1909), O. nagaii Yasunaga 1993 and O. strigicollis (Poppius 1914), and an introduced species for biological control, O. laevigatus Fieber 1860. Orius laticollis Reuter 1884, formally recorded in the Korean Peninsula, is deleted from the Korean fauna registry. The preparation of the macerated slide specimen was applied to this group for the first time, which is confirmed to be effective to identify the Orius species, especially the female specimens whose genital structures have been hardly observed in the traditional dissection method. Observing macerated specimens, new taxonomical characters are documented.

The male specimen is redescribed, illustrated, and measured. To date, three Naratettix species have been recorded on the Korean Peninsula. A key to species of the genus Naratettix from the Korean Peninsula is provided.     

Taxonomie Review of the family Platygastridae (Hymenoptera: Platygastroidea) from the Korean Peninsula

A total of 41 species were investigated, including only one species in the check list of Korean insects, which contains five platygastrids. Eleven species of the family Platygastridae are described as new to science from Korea, viz. Allostemma bicolor Buhl & Choi, Amblyaspis koreana Choi & Buhl, Leptacis koreana Buhl & Choi, L. ocellaris Choi & Buhl, Platygaster ciliata Buhl & Choi, P. flavifemorata Buhl & Choi, P. kui Choi & Buhl, P. tripotini Buhl & Choi, Synopeas collinus Choi & Buhl, S. kimi Choi & Buhl, and S. pumilus Buhl & Choi. Further nineteen species are recorded from The Korean Peninsula for the first time, and some new records are added for eleven species, already known from the Peninsula. Keys are given to the genera and species of Platygastridae hitherto recorded from The Korean Peninsula. As a result, platygastrid fauna of The Korean Peninsula is composed of 68 species up to now.     

First records of Clusia Haliday and Clusiodes Coquillett (Diptera: Clusiidae) from Korea

This study reports the first Korean records of the genera Clusia Haliday and Clusiodes Coquillett (Diptera: Clusiidae), with four newly recorded species, Clusia intermedialis (Mamaev), Clusia nigromaculata (Mamaev), Clusia unita Mamaev, and Clusiodes flaveolus Mamaev. Morphological diagnosis is provided with a key to Korean Clusiidae. The mitochondrial cytochrome c oxidase I (COI) gene sequences of Clusia and Clusiodes are analyzed for DNA barcoding. Molecular analyses of both genera result in well-defined species clusters with significant barcode gaps, and also identify problematic data in the public database.

Both female and male adults are re-described on the basis of specimens obtained from Jeju Island, Korea.     

Taxonomic Review of the Genus Pararrhynchium Saussure (Hymenoptera: Vespidae: Eumeninae) from Korea

Korean Pararrhynchium is taxonomically reviewed, resulting in recognition of two species: P. paradoxum paradoxum and P. ornatum bifasciatulum. The latter is new to Korea. Reviewed taxonomic information on the two species is presented, with male characters of P. ornatum bifasciatum hitherto unknown. The past misidentification of P. ornatum in Korea is ascertained.     

Review of Cotachena Moore, 1885 (Lepidoptera: Crambidae,Spilomelinae) from Korea based on morphology and DNA barcodes

The Korean species of Cotachena were reviewed, based on morphological characters and DNA barcodes. Our study recognized three species of Cotachena from Korea: C. alysoni Whalley, C. brunnealis Yamanaka and C. taiwanalis Yamanaka. The latter two were new to Korea. Dubious occurrence of C. pubescens (Warren) in Korea was discussed. The 23 individuals of COI barcodes were analyzed and assigned to the eleven species of Cotachena. The DNA barcodes of C. taiwanalis and C. brunnealis were provided for the first time and their taxonomic status was discussed. Host plants of C. taiwanalis were first reported. The Korean species of Cotachena were compared to the conspecific populations from neighboring countries. Photographs of habitus and genital features were provided for the Korean Cotachena, if available, to facilitate identification.     

Genetic diversity of genus Vespa including an invaded species of V. velutina (Hymenoptera: Vespidae) in Korea inferred from DNA barcoding data

With about 5000 known species, the Vespidae is a large family belongs to order Hymenoptera. The genus Vespa with 22 species is one of the four genera of the subfamily Vespinae. In Korea, 10 species and subspecies are recognized. Because of their social behavior, their treat to human health and their impact in apiculture, the reliable and sometimes automated identification of these insects to species level are important. To test the efficacy of DNA barcoding method for identification of species of the genus Vespa in Korea, 30 samples of eight Korean species of genus Vespa were collected and mitochondrial DNAs of 658 bp fragment cytochrome oxidase subunit 1 (CO1) region were sequenced. A Bayesian Inference based on COI gene of the Korean Vespa species was constructed. The phylogenetic tree shoed that identification of all specimens is possible based on COI gene and we found strong relation between the sequences of the collected species from different localities in South Korea which clustered together with 100% support with sequences of the same species in GenBank. The results demonstrate that DNA barcoding is a useful technique for rapid and accurate species recognition in Korean Vespa species. The DNA barcode part of COI for V. binghami is provided for the first time that can help for identification of this species through DNA barcoding. Also, the genetic diversity among Korean Vespa velutina was zero suggests that the invasion might have occurred in a single event with small number of founders.     

Taxonomic study on the Phytosciara genus group (Diptera: Sciaridae) in Korea,including the description of a new species

The Phytosciara genus group (Diptera, Sciaridae: Phytosciara Frey, Dolichosciara Tuomikoski, and Prosciara Frey) are studied in the Korean peninsula. Dolichosciara koreaensis Shin & Menzel sp. n. is described and illustrated as new to science. Additionally, four species are reported as new to Korea: Dolichosciara orcina (Tuomikoski, 1960), Dolichosciara semiferruginea (Menzel, 1995), Prosciara producta (Tuomikoski, 1960), and Prosciara ussuriensis (Antonova, 1977). Identification keys are given for the genera of the Phytosciara genus group and for the Korean species of the genera Dolichosciara Tuomikoski and Prosciara Frey. The COI barcode for the new species is studied.

(Nectarosiphon) raphanense sp. nov., collected on Raphanus sativus L. (Brassicaceae). Those three new species are described with biometric measurements and illustrations. Host plants, distributions, identification keys to all Korean Myzus species are presented.LSID urn:lsid:zoobank.org:pub:11DBCB54-E68B-48D2-BC50-915195B67C2A     

Speciation processes within the Korean Peninsula based on the mites from the family Zerconidae (Acari: Mesostigmata)

The mesostigmatid mites speciation of the family Zerconidae in the Korean Peninsula was analysed in relation to the range of this group in the world. The Korean Peninsula is located on the edge of the Holarctic and is characterised by a uniquely diversified climate shaping the longitudinally changing flora. At present, there are altogether 40 genera included in the family Zerconidae. So far, in the Korean Peninsula there have been recognised 18 species of the Zerconidae belonging to 11 genera. The endemic genera within the area include: Metazercon, Eurozer-con, Xenozercon, Koreozercon, Kaikiozercon, Aquilo-nozercon, and cf. Mesozercon gen. nov. A very high level of endemism (over 60%) proves the intensity of the speciation processes within the Zerconidae family on the Korean Peninsula.
