Hypotrachyna (Vainio) Hale is a somewhat rare lichen genus found on the Korean Peninsula. Since it was first recorded more than two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the present study was conducted to carry out a detailed taxonomic and revisionary study of Hypotrachyna in South Korea. This study was based on specimens deposited in the Korean Lichen Research Institute (KoLRI). Detailed taxonomic studies and a literature review confirmed the presence of seven species of Hypotrachyna from South Korea, including one new record, Hypotrachyna nodakensis (Asahina) Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Hypotrachyna species are presented.

The South Korean species of family Proctotrupidae Latreille, 1802 (Hymenoptera: Proctotrupoidea) are studied. Here, seven proctotrupid species are newly added in the South Korean fauna: Cryptoserphus aculeator (Haliday), Disogmus basalis (Thomson), Mischoserphus arcuator (Stelfox), M. samurai (Pschorn-Walcher), Nothoserphus scymni (Ashmead), Proctotrupes gravidator (Linnaeus), and Tretoserphus laricis (Haliday). Which of them, four genera belonging to the tribes Cryptoserphini and Proctotrupini (Cryptoserphus, Mischoserphus, Proctotrupes, and Tretoserphus) are also newly recorded from South Korea. A key to genera of South Korean Proctotrupidae, diagnosis, photographs, distribution, and recorded hosts for each species are presented. All proctotrupid specimens were kept in the collections of the Geolim Entomological Institute, Daegu, South Korea.

The genus Teloganopsis Ulmer belonging to the family Ephemerellidae is only known from the species of T. punctisetae (Matsumura, 1931) in the Korean Peninsula. The members of the genus Teloganopsis are characterized by the following characteristics: head and abdominal tergites without any tubercles and complex setae; forefemur with a row of long and stout setae perpendicularly; maxilla covered with dense setae. A total of 17 species had been previously recorded in this family. Here, Teloganopsis chinoi (Gose, 1980), is newly recorded in Korea which was found under a large stone in Kyeongho river. Larval habitus, habitat, line-drawings of key characters of the species, a checklist with habitus photos of Korean Ephemerellidae, and a key to the larvae of Korean Teloganopsis are provided.

This study was carried out to investigate the occurrence of bug species around bank and paddy field and its peckey rice in four different districts of Kyonggi Area, and then to observe the distribution of bug species causing pee key rice. The results obtained were as follows; Thirty one bug species were collected around bank and its dominant species were Eyarcoris parvus, Nabis stenoferus, Stictopleurus crassicornis and each constituted 35.9, 20.2, 6.5 %, respectively. On the other hand, 11 bug species in paddy field were identified and the dominant species among them were Nabis stenoferus, Adelphocoris triannulatus, Eyarcoris parvus. Pee key rice induced by the infestation of bug species was 34.7% in Eyarcoris parvus and 2.7% in Aeschynteles maculatus. The occurrence of pecked rice injured by bugs was severe on milk ripe stage through heading stage to yellow ripe stage of rice growth period. Peckey rice among rice varieties was higher in Sobaekbyeo, extremely early mature variety, and Taebaegbyeo, early mature variety. The occurrence of peckey rice was higher in mountainous area such as Pocheon culturing early mature rice varieties.

This article reviews Leptotrombidium deliense, including its discovery and nomenclature, morphological features and identification, life cycle, ecology, relationship with diseases, chromosomes and artificial cultivation. The first record of L. deliense was early in 1922 by Walch. Under the genus Leptotrombidium, there are many sibling species similar to L. deliense, which makes it difficult to differentiate L. deliense from another sibling chigger mites, for example, L. rubellum. The life cycle of the mite (L. deliense) includes 7 stages: egg, deutovum (or prelarva), larva, nymphochrysalis, nymph, imagochrysalis and adult. The mite has a wide geographical distribution with low host specificity, and it often appears in different regions and habitats and on many species of hosts. As a vector species of chigger mite, L. deliense is of great importance in transmitting scrub typhus (tsutsugamushi disease) in many parts of the world, especially in tropical regions of Southeast Asia. The seasonal fluctuation of the mite population varies in different geographical regions. The mite has been successfully cultured in the laboratory, facilitating research on its chromosomes, biochemistry and molecular biology.

The distribution of Agrimonia gorovoii Rumjantsev in Korea is verified in this study. The species, described as from Primorsky Krai in Russia, was found in Chungcheongnam-do, Gangwon-do, Gyeonggi-do, and Jeollabuk-do provinces and in Incheon, South Korea. The species is characterized by ten stamens, deeply serrated leaflet margins, and long horizontal pilose stems. A Korean name, Gorovoi-jip-sin-na-mul, for the species is newly given, and a taxonomic description of the species and key to four Korea native Agrimonia taxa are presented.
