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.

This study newly records a deep-sea coral, Flabellum (Ulocyathus) deludens from Korea. The specimens were collected by trawling at a depth of 100 m off Jejudo Island in 2019. The newly recorded species is described and compared with the other similar consubgeneric species in detail based on morphological characteristics, including corallum size, calicular diameter, calicular edge, face angle, edge angle, and septal arrangement. Flabellum(Ulocyathus) deludens is characterized by its solitary, highly compressed, wedge-shaped corallite with a small cylindrical pedicel, radiating inverse chevron-patterned lateral stripes on thecal faces, highly jagged calicular edges, and hexameral septal arrangement in five cycles. As a result of this study, five species in the family Flabellidae have been recorded from Korea.

Braconid wasps is second largest family of Hymenoptera. It is comprising more than 18,000 described species. In Korea, a total of 910 species have been recorded to date. In the present study, nine species of the family Braconidae are recorded for the first time from Korea: Aneurobracon philippinensis (Musebeck), Cenocoelius japonicus (Watanabe), Rattana sinica He & Chen, Adelius clandestinus (Förster), Blacometeorus brevicauda (Hellen), Centistes minutus Chen & Achterberg, Centistes sylvicola Belokobylskij, Gnamptodon sichotaealinicus Belokobylskij, Cotesia urabae Austin & Allen. Diagnosis, distribution and host information for the each species are provided.

Previously only one species, Embolemus ruddii Westwood, 1833, of the family Embolemidae has been recorded in South Korea. As part of a recent study of this family, we newly report four species from South Korea: Embolemus hachijoensis Hirashima et Yamagishi, 1975; E. krombeini Olmi, 1996; E. sensitivus Xu, Olmi et Guglielmino, 2012; Ampulicomorpha thauma Rasnitsyn et Matveev, 1989. The genus, Ampulicomorpha Ashmead, 1893, is recorded for the first time in South Korea. Embolemus ruddii was previously recorded from South Korea because considered synonym of E. walkeri. However, in recent years the two species were separated and E. ruddii was considered absent in the far east, where on the contrary E. walkeri is present. Therefore, five species in two genera are now recognized as the South Korean embolemid fauna. A key to the South Korean Embolemidae species is provided.

A study on Chlorococcal algae was carried out at 33 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2009 to January 2013. The families Hydrodictyaceae and Coelastraceae of order Chlorococcales were investigated, including 5 genera, 29 species, and 17 varieties. Among them, 8 taxa were newly recorded for Korea; 1) Family Hydrodictyaceae: Pediastrum asymmetricum, P. boryanum var. campanulatum, 2) Family Coelastraceae : Actinastrum aciculare, A. hantzschii var. subtile, Coelastrum indicum, C. microporum var. octaedricum, C. morus, C. pulchrum.

A study on Chlorococcal algae was carried out at 21 stations (ponds, swamps, reservoirs, lakes and rivers) from May 2011 to January 2012. The families of Botryococcaceae and Characiaceae of Chlorococcales were investigated to the extent of 8 genera, 20 species. Among them, 10 taxa are newly recorded in algal flora of Korea by Kim and Kim (2012) and this study reviewed about ; 1) Family Botryococcaceae: Dictyosphaerium elegans, D. reniforme, D. simplex, D. elongatum, 2) Family Characiaceae: Characium conicum, Ankyra ancora, A. judayi, A. calcarifera, Schroederia spiralis, S. indica.
