The aim of this study was to discover and describe new genera and species of cyanobacteria in Korea. Aquatic and aerial algae were collected from various environments in the Han River and Nakdong River watersheds between August 2009 and October 2015. As a result, one genus and six species of cyanobacteria were newly recorded in Korea. The newly recorded genus for Korea was Capsosira; newly recorded species were Capsosira brebissonii, Rivularia minutula, Chamaesiphon amethystinus, Leptolyngbya margaretheana, Pseudanabaena arcuata, and Rhabdoderma lineare.

Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.

Phytoplanktons were collected from various environments including small marshes, small ponds, reservoirs and brackish water from March 2017 to November 2017. In this study, five species of family Scenedesmaceae were newly recorded in Korea. The genus Desmodesmus was newly reported in Korea. The newly recorded species are Scenedesmus nanus, S. praetervisus, Desmodesmus costato-granulatus, D. lunatus and D. spinulatus. S. nanus and S. praetervisus are known to occur in freshwater, but they were found in the brackish water in this study.

Three species of the genus Dohrniphora, viz., D. cornuta, D. malaysiae, and D. prescherweberae were newly recorded from Korea. These newly recorded species can be easily identified by the characteristic that inner face of male hind femur equipped with a group of peg-like stout setae on basal sensory area. Peg-like setae are arranged perpendicularly in D. cornuta whereas linear in D. malaysiae and somewhat arched in D. prescherweberae. Also, concave area near the peg-like setae is also well developed in male which is smooth in D. cornuta, on the other hand, there is well developed distal carina in D. malaysiae and with groups of microtrichia in D. prescherweberae. In this study, detailed descriptions with photographs of three newly recorded species and a key to males of all Korean Dohrniphora species are provided.

A newly recorded species Orientomaera incisa Ariyama, 2020, belonging to the family Maeridae Krapp-Schickel, 2008, was collected from the sublittoral waters of the East Sea, Korea. Previously, only one species, O. brevispina (Kim and Kim, 1991), was reported in Korea. This species morphologically similar to O. brevispina however, the species can be easily distinguished from the O. brevispina by having two distinct teeth on palm of gnathopod 2. The newly recorded species is described and fully illustrated in the present study.

One of the largest genera of subfamily Ophioninae, Ophion, has been reported 144 species in the World. Nevertheless, recorded members of genus Ophion are 40 species in the Eastern Palaearctic region, 8 in South Korea (O. ainoicus, O. choaspese, O. flavopictus, O. fuscomaculatus, O. luteus luteus, O. obscuratus obscuratus, O. okunii, O. takaozanus). In this paper, a taxonomic list of genus Ophion from South Korea is provided for the first time. Two newly recorded species, Ophion hokkaidonis Uchida and Ophion nikkonis Uchida, are reported from South Korea. A key to these South Korean species, diagnoses of the two newly recorded species and digital images are provided.

In this study, aquatic and aerial algae were collected in various environments in Hongcheon-river of Gangwan-do between December 2011 and June 2012, with the aim of adding newly described genera and species to the Korean flora. As a result, five genera and eight species were recorded for the first time in Korea. These newly recorded genera and species were Cylindrocapsa geminella, Leptosira mediciana, Pseudendoclonium basiliense var. brandii, Stichococcus minor, S. deasonii, Eustigmatos polyphem, Nephrodiella lunaris, and Xanthonema exile. The eight taxa identified in this study mostly corresponded to their reported morphological characteristics. However, some differences from previous published descriptions were found; N. lunaria, reported to be an aquatic species in a previous study, was found to be an aerial algae inhabiting on rocks and mosses. Cylindrocapsa geminella was found to transform into attached or planktonic algae depending on the environmental condition, and the cell wall was found to be changed. Likewise, E. polyphem was seen to change cell-shape or chloroplast color according to the environment.

Two newly recorded species of melitid amphipod, Abludomelita japonica (Nagata, 1965) and A. okhotensis Labay, 2016 belonging to the family Melitidae Bousfield, 1973 were collected from Korean waters. To date, only two genera, Dulichiella Stout, 1912 and Melita Leach, 1814, of the 28 genera of Melitidae have been recorded in Korea, so this is the first record of the genus Abludomelita from Korea. The genus Abludomelita Karaman, 1981 is morphologically similar to Melita Leach, 1814, however they are distinguished by having oblique row of setae on inner lobe of maxilla 2. Both newly recorded species are fully illustrated and compared with related species.

We present brief descriptions of the Korean Xylotrechus species, except four species which could not be examined in this study. The geographic distribution, host plants, illustrations for each species, and a key to the Korean Xylotrechus species are provided.
