One species of the genus Camponotus Mayr was newly recorded in South Korea. It was collected from Suhari, Subi-myeon, Yeongyang-gun and Gyeongsangbuk-do. Its corresponding descriptions, measurements and photographs were supplemented for the Camponotus yessensis Yasumatsu & Brown 1951.

The present study summarized the occurrence, distribution and autecology about 31 taxa of the green algae (Chlorophytes) collected from several swamps, reservoir and highland wet-lands in the South Korea from 2010 to 2013. This paper deals with a total 31 taxa including of 26 genera which are recorded for the first time in Korea. Among these algae, 18 genera including Pyrobotrys Arnoldi, Volvulina Playfair, Dicellula Svirenko, Echinocoleum Jao & Lee, Hofmania Chodat, Gloeotila Kutzing, Tetrachlorella Korschikov, Botryospherella P.C.Silva etc., were newly recorded in Korean fresh-water algal flora.

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.

The present study summarizes the taxonomic description and Korean distribution of 16 taxa that are recorded for the first time in Korea. These taxa classified into Chlorophyceae (Astrephomene gubernaculifera, Botryococcus protuberans, Chlorangiella polychlora, Cylindrocapsa geminella, Kirchneriella contorta var. gracillima, Korshikoviella gracilipes, Oocystis naegelii, O. ovalis, Stylosphaeridium stipitatum), Charophyceae (Cosmarium moniliforme, Cosmocladium constrictum, C. perissum), Xanthophyceae (Tetraedriella tumidulum, T. spnigera), Chrysophyceae (Cyclonexis erinus) and Cyanophyceae (Arthrospira platensis). Among these taxa, six genera including Astrephomene, Chlorangiella, Cosmocladium, Cyclonexis, Stylosphaeridium, and Tetraedriella are newly recorded in Korea.

In 2017, the freshwater algae were collected from reservoirs, small ponds, soil, and rocks in Korea. Eight taxa of Chlorophyta (Chlorophyceae and Trebouxiophyceae) have been newly reported in Korea. The unrecorded indigenous species were Chlorolobion braunii, Coelastrum pseudomicroporum, Coelastrum reticulatum var. cubanum, Monoraphidium nanum, Tetrachlorella incerta, Ecdysichlamys obliqua, Gloeotila scopulina, and Stichococcus jenerensis.

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.

Background: Species in the heterokont genus Synura are colonial and have silica scales whose ultrastructural characteristics are used for classification. We examined the ultrastructure of silica scales and molecular data (nuclear SSU rDNA and LSU rDNA, and plastid rbcL sequences) to better understand the taxonomy and phylogeny within the section Petersenianae of genus Synura. In addition, we report the first finding of newly recorded Synura species from Korea. Results: We identified all species by examination of scale ultrastructure using scanning and transmission electron microscopy (SEM and TEM). Three newly recorded species from Korea, Synura americana, Synura conopea, and Synura truttae were described based on morphological characters, such as cell size, scale shape, scale size, keel shape, number of struts, distance between struts, degree of interconnections between struts, size of base plate pores, keel pores, base plate hole, and posterior rim. The scales of the newly recorded species, which belong to the section Petersenianae, have a well-developed keel and a characteristic number of struts on the base plate. We performed molecular phylogenetic analyses based on sequence data from three genes in 32 strains (including three outgroup species). The results provided strong statistical support that the section Petersenianae was monophyletic, and that all taxa within this section had well-developed keels and a defined number of struts on the base plate. Conclusions: The phylogenetic tree based on sequence data of three genes was congruent with the data on scale ultrastructure. The resulting phylogenetic tree strongly supported the existence of the section Petersenianae. In addition, we propose newly recorded Synura species from Korea based on phylogenetic analyses and morphological characters: S. americana, S. conopea, and S. truttae.

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).

Cyanobacteria were sampled at five sites in the Han River, Nakdong River, and Geum River watershed from June 2014 to May 2015 and then cultivated. Two genera and five species of the cyanobacteria were newly recorded in Korea. The newly recorded species were Limnothrix redekei, Pseudanabaena galeata, Pseudanabaena amphigranulata, Sphaerospermopsis aphanizomenoides, and Calothrix parietina. As a result, the Korean flora of the cyanobacteria now include four orders, 22 families with 73 genera, 143 species, and two varieties, giving a total of 146 taxa.

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.
