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.

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.

We report three newly recorded campoplegine species, Klutiana jezoensis (Uchida, 1957), Dusona maruyamator Hinz, 1979, Dusona petiolator (Fabricius, 1804), for the first time from Korea. Genus Klutiana Betrem (1933), is firstly recorded from Korea. Photographs and diagnosis are provided for identification.

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.

The freshwater algae were collected at reservoirs and small ponds in Gyeonggi-do and Jeju-do on June 2016. Four species of Korean previously unrecorded algae were collected in domestic fresh waters: Coelastrum rugosum, Cosmarium baccatum, Cosmarium norimbergense and Staurastrum connatum var. pseudoamericanum. The morphological characteristics of the four taxa identified in this study were showed mostly similar to the characteristics of the previously reported characteristics. However, Cosmarium baccatum was larger than the previously recorded species and Staurastrum connatum var. pseudoamericanum was wider than the previously recorded 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).

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 rare genus Leptodromiella Tuomikoski, 1936, which belongs to the subfamily Ocydromiinae in the family Hybotidae contains only one recorded speices, L. crassiseta (Tuomikoski, 1932). Until now, there is still no known ecological information about this genus, and its distribution was restricted to only in central and northern Europe, such as Finland, Sweden and Russia. In Korea, only one species, Bicellaria koreana Barták, Plant & Kubík, 2013, was recorded in the family Hybotidae from Mt. Baekdusan so far. Herein, the second genus Leptodromiella is newly recorded along with the nominate species, L. crassiseta (Tuomikoski, 1932) in Korean fauna. Re-description and illustrations of external features and male genitalia of the newly recorded species are provided in this paper.

Two newly recorded species of Melastomataceae, Medinilla rubicunda and M. septentrionalis, were found from the Phnom Bokor National Park and the Central Cardamom Protected Forest in Cambodia. Medinilla rubicunda is similar to M. laurifolia from Indonesia (Sumatra and Java) and Thailand, but is readily distinguished from the latter by its shorter petiole and a cyme bearing fewer than six flowers. Medinilla septentrionalis is similar to M. nana from China (Yunnan) and Vietnam, but is clearly distinguished from the latter by its terete branchlets, which have a thin and not a corky bark. Descriptions, photographs, and a diagnostic key of the three species of Cambodian Medinilla are provided for species identification.

Three species belonging to genera Acaphylla Keifer and Calacarus Keifer (Prostigmata: Eriophyidae) that cause damage to Camellia (Theaceae) plants, have been newly recorded in Korea. The three species, Acaphylla theae (Watt), Acaphylla theavagrans Kadono, and Calacarus carinatus (Green), have been redescribed and illustrated. Keys to Korean species of the genus Acaphylla; their distribution; and biological information, such as host plants and damage symptoms, are also presented.
