Aerial algae were sampled from 28 sites on rocks, tree barks, and mosses along the Hongcheon-river in Gangwon-do, Korea, from December 2011 to September 2012 and then cultivated. Seven genera and eight species of the order Chlorococcales were newly recorded in Korea. These were Spongiococcum tetrasporum, Tetracystis aggregata, Myrmecia bisecta, Coenocystis inconstans, Lobosphaeropsis pyrenoidosa, Pseudococcomyxa simplex, Coelastrella oocystiformis, and C. vacuolata. As a result, the known Korean flora of the order Chlorococcales now includes 12 families with 54 genera, 263 species, 76 varieties, and 27 forma, giving a total of 366 taxa.

A total of 69 genera and 202 species of the family Syrphidae have been previously recognized in Korea. In the present study, we report the following 10 species new to Korea: Epistrophe aeka Kimura, 1989, Epistrophe aino (Matsumura, 1917), Epistrophe annulitarsis(Stackelberg, 1918), Epistrophe griseofasciata (Matsumura, 1918), Epistrophe sasayamana (Matsumura, 1918), Epistrophe shibakawae (Matsumura, 1917), Fagisyrphus cinctus (Fallén, 1817), Melangyna olsufjevi (Violovitsh, 1956), Melangyna pavlovskyi (Violovitsh, 1956), and Paragus clausseni Mutin, 1999. Among the four genera, the genus Fagisyrphus Dušek and Láska, 1967 is recognized for the first time in Korea. As a result, 70 genera and 212 species of the family Syrphidae are now officially recognized for the Korean fauna. For each newly recognized Korean species, we provide synonymy, diagnosis, and description with color photographs. In addition, we provide new Korean names for all newly recorded species as well as the genera Epistrophe, Fagisyrphus, and Melangyna, which previously did not have Korean names.

One of the small genera of the tribe Atrophini (subfamily Banchinae), the genus Amphirhachis, has been reported seven species in the world. Among them, four species (Amphirhachis fasciata, A. nigripalpis, A. rubriventris and A. tertia) from Oriental region, and four species(Amphirhachis fujiei, A. miyabi, A. nigra and A. tertia) from Eastern Palaearctic region. Unfortunately, there are no records in South Korea yet. This genus is easily distinguished from other genera of Atrophini following: clypeus strongly convex near side; posterior transverse carina of propodeum represented by a weak or faint vertical ridge at apex on each side; ovipositor sheath shorter than metasoma. In this study, the genus Amphirhachis is recorded for the first time with a newly recorded species (Amphirhachis tertia) from South Korea. New data on the taxonomy and distribution of Amphirhachis tertia are given. We also provide diagnosis and digital images of a newly recorded genus and species.

The samples were collected at lowland swamps, reservoirs, mountainous wetlands, and sphagnum bogs from 2012 to 2014. The followings were newly recorded in Korea: two species, three varieties, and one form, including six taxa of the genus Cosmarium. The newly recorded Korean species were Cosmarium bioculatum var. hians, C. bireme, C. pseudobiremum, C. nitidulum var. pseudorectangulare, C. trilobulatum f. retusum, and C. trilobulatum var. depressum. The flora of the genus Cosmarium contains 303 taxa in total in Korea. The specimens were cultured and deposited on the algal culture collection of Kyonggi University (ACKU) and National Institute of Botanical Resources (NIBR).

Abludomelita rotundactyla (Ren, 2012), belonging to the family Melitidae Bousfield, 1973 has been collected from Baengnyeongdo Island and Yangyang in Korea. This species was previously known from Yellow Sea, China and Sakhalin Island, Russia. Abludomelita rotundactyla is morphologically distinguished from congeners by gnathopod 2, palm excavate, defined by midventral acute process; gnathopod 2 with prominently plump dactylus; pleonites and urosomites dorsal formulae 7-9-9-5-4; and epimeron 3 with posterior serrations. The newly recorded species in Korea, A. rotundactyla is well accorded with the original description except for the number of pleonites dorsal teeth. The newly recorded species is described and fully illustrated in the present study. A key to the Abludomelita species in Korea is also provided. This additional record now brings the total recorded number of abludomelitid species to three in Korea.

The giant crab spider genus Sinopoda in Korea is reviewed with detailed illustrations of male palpal organs. Three species, S. forcipata, S. stellatops, S. koreana are recognized with newly collected specimens. The first species is recorded newly in Korean spider fauna. A key to the species of the Korean Sinopoda spiders are also provided.

A faunal study on Amphipods belonging to the class Malacostraca was conducted 26-29 August 2021 at 12 sites in Chujado Island, Korea. This study found that 68 amphipod species in 39 genera, 19 families were living on Chujado Island. Among these 19 families, the family Caprellidae (20 species) showed the highest abundance. Ampithoidae (7 species) and Dexaminidae (6 species) were subdominant families. The species Stenothoe valida Dana, 1852 (found at 10 of 12 sites) was the most frequent and widespread species. Caprella scaura Templeton, 1836 was identified at 9 of 12 sites and had the highest frequency of appearance among 20 species of Caprellidae. Among the 68 species, Ampithoe waialua J.L. Barnard, 1970 and Melita nagatai Yamato, 1987 are newly recorded species in Korean fauna. These newly recorded species are fully illustrated and compared with related species. We provide an amphipod fauna in Chujado Island with a list, figures, and a table.

A newly recorded species, Sinocorophium dongtanense, of the genus Sinocorophium was collected from shallow waters of Korea. This species was previously reported as S. homoceratum in Korea. However, after reanalysis of previously studied samples, this species was identified as S. dongtanense, which had previously been reported from the Yangtze estuary, Shanghai, China in 2014. In this study, the newly recorded species is illustrated with a diagnosis and compared to the previously misidentified species. Molecular phylogenetic studies for Sinocorophium species in Korea are provided. A key to the Sinocorophium species in Korea is also provided.

Short-palped crane flies belonging to the genus Epiphragma Osten Sacken, 1860 (Diptera: Limoniidae: Limnophilinae) have a worldwide distribution except the Afrotropics, with the highest diversity in Neotropics and Oriental Region. They are divided into four subgenera: Eupolyphragma Alexander, 1948, Epiphragma s. str., Lipophragma Alexander, 1978, and Parepiphragma Alexander, 1960. Diagnostic characters and wing photographs of all subgenera are given. Genus Epiphragma was previously unknown from the Korean Peninsula. Species Epiphragma (Epiphragma) gracilistylus Alexander, 1933 is newly recorded for North Korea, E. (E.) subfascipenne Alexander, 1920 is newly recorded for South and North Korea, and E. (E.) subinsigne Alexander, 1920 is newly recorded for South Korea. These species are taxonomically revised, and the taxonomic status of E. (E.) gracilistylus is discussed. We present an identification key and redescriptions and illustrations of both sexes from all species in Korea. Redescription of larva and pupa of E.(E.) subfascipenne is presented. Elevation range, period of activity, habitat information, general distribution, and a distribution map in Korean Peninsula is given for each species.

This research includes the identification and cultivation of aerial algae from 33 sites located in Mt. Gwanggyo of Gyeonggi-do, Korea, from March 2011 to August 2012. The ecological factors of aerial algae were analyzed and a total of 29 taxa were identified in 4 phyla, 5 classes, 11 orders, 15 families, 19 genera, 28 species and 1 variety; 12 taxa of cyanophytes, 8 taxa of chrysophytes, and 9 taxa of chlorophytes were found. As for newly recorded cyanophytes of Korea, Komvophoron jovis, Microcoleus steenstrupii, and Nostoc edaphicum appeared. Komvophoron jovis, previously known to grow on rocks and boulders, appeared in soil. Microcoleus steenstrupii, reported to appear in desert soils, appeared on the wet surface of the soil after rain. Nostoc edaphicum, in symbiosis with fungi, appeared on tree bark as the lichen. Thus, there are a total of 99 reported taxa of Korean aerial algae, including 3 species that were discovered in this study.
