Taxonomic Notes on Two Apolygus Species (Heteroptera: Miridae: Mirinae) in Korea

Apolygus subhilaris (Yasunaga 1992) is reported for the first time from the Korean peninsula, and a new host plant of A. watajii Yasunaga and Yasunaga 2000 is confirmed. Diagnostic characters to separate them from allied species are given with photos of dried specimens, male genitalia and live adults. A key to Korean Apolygus species 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.     

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.     

Total‐evidence phylogenetic analysis and reclassification of the Phylinae (Insecta: Heteroptera: Miridae), with the recognition of new tribes and subtribes and a redefinition of Phylini

The subfamily Phylinae (Heteroptera: Miridae) is one of the largest subfamilies of plant bugs and in the most recent classification comprised six tribes: Pilophorini, Hallodapini, Auricillocorini, Phylini, Pronotocrepini, and Leucophoropterini. Phylogenetic analyses of the subfamily using dynamic homology (POY), parsimony (TNT), and model‐based (RAxML) methods are presented. A dataset comprising both morphological and molecular characters (16S, 18S, 28S, and COI–COII) was assembled for taxon samples of 164 ingroup and nine outgroup taxa. A reclassification of the subfamily based on the POY analysis is presented, recognizing nine tribes and nine subtribes. The Auricillocorini is synonymized with the Hallodapini and the Pronotocrepini with the Cremnorrhini; the Phylini was found to be polyphyletic and is redefined; the Semiini and Nasocorini are resurrected and redefined; and the Decomiini and Coatonocapsiniare presented as new tribes. The Hallodapini, rather than the Pilophorini, was found to be the sister‐group to the remaining Phylinae.     

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.     

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.     

One new record of the genus Aulacorthum (Hemiptera: Sternorrhyncha: Aphididae) from Korea

Aulacorthum vandenboschi was recognized for the first time in Korea on Cirsium japonicum var. ussuriense in Jeju-do. The apterous viviparous female is redescribed, illustrated, and measured. To date, 15 species of the genus Aulacorthum have been recorded on the Korean Peninsula. A key to species of the genus Aulacorthum from the Korean Peninsula is provided.     

Taxonomic review of genus Sejanus Distant (Heteroptera: Miridae: Phylinae) from Korea,with a new species

Four species of Sejanus Distant, 1910 recognized from the Korean Peninsula including the first record of S. komabanus (Yasunaga et al., 2013), S. vivaricolus (Yasunaga et al., 2013) and a new species herein described, S. yasunagai Oh, Duwal & Lee sp. nov.

(Uromelan) chrysanthemicola sp. nov., on Chrysanthemum sp. (Asteraceae) from Mt. Oseo, Korea and U. (Uroleucon) jejuni sp. nov., on Echinops setifer Iljin (Asteraceae) from Jeju Island, Korea. Two new species are described with biometric measurements, illustrations, and identification keys to species on host plants.LSID urn:lsid:zoobank.org:pub:ADBBDD99-6A12-4854-B559-64D5EF1B9CB0.     

Taxonomic review of the tribe Anthocoptini (Acari: Eriophyidae) from Korea

A total of eight species in the tribe were presented, among them, four species, Abacarus hystrix (Nalepa), Aculus fockeui (Nalepa and Trouessart), Aculus schlechtendali (Nalepa) and Tegolophus zizyphagus (Keifer) were newly recorded to the fauna. All the Korean species of the tribe were redescribed and illustrated. Keys to the Korean species of the tribe and distributions were also presented with the biological information such as host plants and damage symptoms.
