A Korean indigenous species, Protaetia brevitarsis seulensis (PBS), is popularly reared at many insect farms as valuable industrial insect resources in South Korea. However, there is no comprehensive study on the genetic diversity within the Korean PBS population as well as between morphologically closed species. Employing the rapidly evolved genetic markers such as mitochondrial DNA is important in the detection of haplotype diversity and rapid species identification of larval stage and/or its processed goods. We here examined how many genetically different haplotypes distribute in the reared PBS collected from 14 insect farms and the interspecific genetic difference between congeners using mitochondrial COI gene sequences (DNA barcoding region). As a results, the PBS was clearly separated from two related species with large genetic distances (7.98%~8.86%). In the PBS, 57 haplotypes were detected from 223 specimens with low intraspecific genetic distance (~1.3%). Among them, the most dominant haplotypes are subsequently detected in H4 (25.6%), H38 (15.7%) and H26 (10.3%). From the haplotype network and distribution analyses, we consider that many haplotypes have been mixed by artificial collections from various local places and exchanged between insect farms within South Korea. We expect that this data will be helpful in rapid species identification for its processed goods, and understanding the exact population diversity and detection of the original habitats for each haplotype of the reared PBS throughout comparing with natural populations in the further study.

The previous studies for phylogenetic relationships within Elateridae were carried out, but not constructed a reliable evolutionary hypothesis. This study attempted to establish a robust evolutionary hypothesis, focusing on major subfamilies of the family Elateridae sensu stricto, using extensively selected 12 genetic markers, COI, 16S rRNA, 18S rRNA, 28S rRNA and 8 nuclear genes. As the results, phylogenetic analyses for 12 multiple genes constructed robust phylogeny with almost very strongly supported nodal values (>90%) and represented that the previously questioned systematic positions of nine subfamilies are fully resolved, excepting the basal lineage split. Especially, three subfamilies, which were recently reduced into tribal rank, Hypnoidinae, Oxynopterinae, and Denticollinae are monophyletic, respectively, and it is supported the traditional taxonomic schemes that had been treated these three taxa in subfamily rank. Whereas, Elaterinae, Hiopinae, and Melanotinae are clustered to a monophyletic group. Two tribes, Denticollini and Ctenicerini in Denticollinae are paraphyletic, respectively and it needs to reclassify their systematic positions. This study recovering of relationships between subfamilies using 12 gene loci resulted that their phylogenetic relationships are sufficiently and successfully resolved with strong supported nodes and provided more possible interpretations from subfamily to tribal levels than the previous studies.
A taxonomic review of the genus Acteniceromorphus Kishii, 1955 (Coleoptera; Elateridae) in Korea
Han, Taeman,Park, In Gyun,Park, Haechul Korean Society of Sericultural Science 2015 International Journal of Industrial Entomology Vol.31 No.2
The genus Acteniceromorphus is taxonomically reviewed for the first time in Korea. From the previously recorded three species, two species, A. selectus (Candèze, 1894) and A. fulvipennis <xref>(Lewis, 1894)</xref> are confirmed as misidientification of species which are endemic to Japan. Another species, A. chlamydatus <xref>(Lewis, 1894)</xref> is unavailable any Korean specimens. Additionally, we found A. ferrugineipennis <xref>(Candèze, 1879)</xref> as new to Korea. We also provide a comparison of DNA barcoding for two species previously misidentified and the newly recorded species, except A. chlamydatus. DNA barcoding result shows that each species is clearly delimited at species-level from each other by large interspecific genetic distance over 7.2%.
New Record of Ptecticus sinchangensis Ouchi, 1938 (Diptera, Stratiomyidae, Sarginae) in Korea
( Taeman Han ),( Tae Hwa Kang ),( Seung-hyun Kim ),( In Gyun Park ),( Haechul Park ) 한국잠사학회 2018 International Journal of Industrial Entomology Vol.37 No.2
In Korea, species of the genus Ptecticus Loew, 1855 (Family Stratiomyidae) have been known as three species, P. aurifer (Walker, 1854), P. matsumurae Lindner, 1936 and P. japonicus (Thunberg, 1789) (= P. tenebrifer (Walker, 1849)). Additionally, an unrecorded species, P. sinchangensis Ôuchi, 1938, was found in Korea. We therefore report the species for the first time in Korea with morphological diagnosis and key for the identification of the Korean species of the genus. In total, the members of the genus Ptecticus are officially recognized as four species in Korea.
A New Species of the Genus Neopsephus Kishii 1990 (Coleoptera: Elateridae: Elaterinae) from Korea
Taeman Han,Jong Chel Jeong,Young Bo Lee,Seunghwan Lee,Hae Chul Park 한국응용곤충학회 2012 한국응용곤충학회 학술대회논문집 Vol.2012 No.10
We recognize a new species, belonging to the genus Neopsephus Kishii 1990, from Is. Jeju. The novel species is closely allied to N. takasago Kishii 1990 known from Taiwan. This study provides the detailed morphological characteristics investigated by SEM and molecular data inferred from COI and 16S rRNA of mitochondria.
A taxonomic note on the genus Scutellathous Kishii, 1955 (Coleoptera, Elateridae) in Korea
Han, Taeman,Lee, Seunghwan,Park, In Gyun,Park, Haechul Korean Society of Sericultural Science 2016 International Journal of Industrial Entomology Vol.33 No.2
The genus Scutellathous Kishii, 1955 is a small group known from Korea, Japan, and Taiwan. We carried out a taxonomic study on the Korean species of Scutellathous for the first time. As the result, S. porrecticollis (Lewis, 1894) is revealed to be commonly distributing in Korea and Japan. Additionally, we found that the previous record of Athous jactatus (Lewis, 1894) from North Korea is misidentification of S. porrecticollis. We herein provide redescription of S. porrecticollis and the result of DNA barcoding of congeners belonging to Scutellathous.
Is a Natural Monument, Chrysochroa fugidissima (Coleoptera; Buprestridae) a Novel or Not?
Taeman HAN,Taehwa KANG,Yongbo LEE,Jongchel JEONG,Hyojung CHUNG,Seunghwan LEE,Ki-Gyoung KIM,Haechul PARK 한국응용곤충학회 2010 한국응용곤충학회 학술대회논문집 Vol.2010 No.05
Chrysochroa fulgidissima is the most beautiful Korean beetle and valuable insect in traditional culture because of ancient fulgidissima's adornments in Korea and Japan. The species is also recognized as very rare in the Korean fauna. However, we recently realized that the Korean population has been applied to Ch. fulgidissima without detailed taxonomic approaches since Japanese colonial rule of Korea. Therefore, we investigated 76 dried specimens belonging to seven populations collected from N. Vietnam, E. China, Taiwan, Japan, and Korea through morphological and molecular taxonomy using DNA barcoding of COI and 16S rRNA. As the result, the Korean population is strongly formed a monophyletic branch divided from other populations by genetic divergence of each 10.2%~11.7% in DNA barcoding and 6.4%~7.9% in 16S rRNA, and as well as fine structure in the male genitalia. It is allowed to us that the Korean population, which has been underestimated at species discrimination in morphology, may be considered as a novel species.

This taxonomic study on the genus Scutellathous is only recognized a species. S. porrecticollis (Lewis, 1894) in Korea. The previous record of Athous (=Medakathous) jactatus (Lewis, 1984) is revealed as the misientification of S. porrecticollis. We also describe and illustrate Subscutellathous koreanicus gen. and sp. nov. from Korea. This new genus si compared to the most closed genus Scutellathous by the basis of diagnostic characters in generic level.
