We reviewed South Korean species of the genus Apechthis and confirmed four species and two subspecies. In this genus, four species and one subspecies have been reported from the Eastern Palaearctic region, two species and one subspecies were from South Korea. Additionally, we report two species and one subspecies, Apechthis compunctor orientalis Kaspryan, 1973, Apechthis quadridentata (Thomson, 1877) and Apechthis rapae (Uchida, 1925), which were newly recorded for the first time from South Korea. A key to South Korean species of the genus Apechthis, redescriptions of newly recorded species and subspecies and digital images of South Korean Apechthis are provided.

Dinoflagellate species composition has changed around Jeju Island as well as in Korean waters due to global warming and climate changes. An investigation was conducted to monitor changes in planktonic dinoflagellates around Jeju Island from June 2006 to September 2009. A total of 86 species belonging to 14 families and 15 genera were identified, of which 34 species were newly recorded in Korean waters. Among the newly recorded species, >20 were confirmed as tropical species. Thus, the occurrence of such tropical dinoflagellates could be an indicator to monitor of environmental changes including global warming around Jeju Island and in Korean waters.

The classification system of Collybiopsis has been updated to contain some species of Collybiopsis, Gymnopus sect. Vestipedes, and Marasmiellus. Recently, we conducted the taxonomic study of Korean Collybiopsis to reflect the current classification system and confirmed 16 species. We propose their Korean names in this research note.

A newly recorded species, Boehmeria nakashimae Yahara, is confirmed for the first time to be distributed on forest edges on Jejudo Island, Korea. This species is known to be endemic to northern Kyushu, Japan. It is characterized by ovate to broadly ovate, elliptic-ovate, or sub-orbicular middle leaf shapes, serrulate-dentate and uniform margins, 17-29 teeth on one side, a short caudate or narrowly acute apex, dense glomerules at fruiting, and densely strigillose on the stems, both surfaces of the leaves, the perianth of staminate flowers, and achenes. Therefore, it is given the new name 'Je-ju-top-mo-si-pul' in Korean based on its serrulate-dentate leaf margin and geographical distribution. A description, photographs, illustrations, and keys of related taxa in Korea are provided.

Kim (1970) was an early, comprehensive foundation for the taxonomy of Korean spider wasps. All the species therein are reviewed, and an annotated checklist comprising 21 species is presented. Species names are corrected in terms of current taxonomy. Based on the re-examination of voucher specimens, five misidentifications are rectified, of which two species rectified as Priocnemis(Leptopriocnemis) cyphonota and P.(Umbripennis) pseudojaponica are new to Korea. Also, occurrences of two species (Anoplius eous and An. viaticus) in Korea, which was doubted by Lelej et al. (1994), are confirmed. On the other hand, exclusions of two species (Irenangelus perinx and Priocnemis mitakensis) from the Korean fauna are proposed. However, the need for further study on six species (Anoplius reflexus, An. infuscatus, Arachnospila eisukei or Ar. fumipennis eisukei, Auplopus obtusus, Priocnemis irritablis) historically mentioned for the Korean fauna is newly recognized. The current taxonomic status of those species is briefly discussed.

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 (Lewis, 1894) are confirmed as misidientification of species which are endemic to Japan. Another species, A. chlamydatus (Lewis, 1894) is unavailable any Korean specimens. Additionally, we found A. ferrugineipennis (Candèze, 1879) 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%.

Two monstrilloid copepod species belonging to the genus Monstrilla Dana are newly recorded from Korea: M. grandis Giesbrecht, 1891 and M. hamatapex Grygier and Ohtsuka, 1995. Specimens were obtained from inshore waters around the coasts of South Korea, using a light trap installed at quays and wharves overnight. Based on the Korean specimens, the two species are redescribed, with brief accounts of their affinities and morphological variabilities. Remarkable morphological discrepancies are confirmed in female leg 5 of M. grandis between type material from Southern Hemisphere and European and Asian specimens, which raise a strong doubt on their conspecificity. Korean specimens of M. hamatapex well coincide with the type specimens from Japan, except for some variations in the setal armature of leg 5 and antennules. This is the second taxonomic paper on the monstrilloid copepods in Korea, and the genus Monstrilla is newly added to Korean fauna.

Chrysosplenium grayanum Maxim. (Series Nepalensia), which had been known to be restricted to Japan, was newly discovered from Mt. Cheongtae in Yeonggwang-gun, Jeollanam-do, located in the southern part of the Korean Peninsula. Species identification was confirmed using morphological characteristics and DNA sequence data, while comparing with materials obtained from Japan and herbarium specimens. Chrysosplenium grayanum is clearly distinguished from the remaining taxa of the genus Chrysosplenium by having glabrous plant body, opposite leaves, cylindrical papillae with roundish head at the tip on the smooth seed surface, and four stamens. Molecular sequence data of the nuclear ribosomal ITS regions, chloroplast rbcL and matK genes strongly supported that this previously unknown Chrysosplenium species from Korea is C. grayanum. Taking the molecular and the morphological evidence into consideration, it is clear that newly discovered Chrysosplenium population in Korea is conspecific with the widely distributed C. grayanum in Japan. In this paper, we provide a description, illustration, and photo images of Chrysosplenium grayanum from Korea and also a key to the Chrysosplenium species in Korea.

We reviewed Korean species of the genus Pimpla and confirmed 12 species. In this genus, 36 species have been reported from the Eastern Palaearctic region, eight species were from Korea. Also, we report four species, Pimpla albociliata Kasparyan, 1974, Pimpla femorella Kasparyan, 1974, Pimpla kaszabi (Momoi, 1973) and Pimpla melanacrias Perkins, 1941, which were newly recorded for the first time from Korea. Among them, Pimpla nipponica Uchida, 1928 is recorded from United States and the Nearctic region for the first time. A key to Korean species of the genus Pimpla, diagnoses and illustrations of adult external structures are provided.

Anteholosticha bergeri and Bakuella granulifera were isolated from soil samples collected from Muuidong and Songdo-dong, Incheon and confirmed new to South Korea. Including these two newly recorded species, 11 species of Anteholosticha and four species of Bakuella have been recorded in South Korea to date. Anteholosticha bergeri was discriminated from congeners by following characters: cortical granules, 12-16 macronuclei, 5-8 midventral pairs, 2-3 pretransverse cirri, 4-6 transverse cirri, and three dorsal kineties. Bakuella granulifera was identified by cortical granules, 5-11 buccal cirri, 2-5 frontoterminal cirri, 2-5 midventral cirri rows, and 8-12 transverse cirri. The Korean A. bergeri population corresponds to the Austrian population, except for the number of marginal and transverse cirri, and the Korean B. granulifera population corresponds to the Namibian population, except for body size. In addition, small subunit ribosomal RNA(18S rRNA) gene sequences from both species were determined.
