  • Aquilonastra doranae, a newly recorded sea star, was collected from the southern coast of Jejudo Island by a trimix SCUBA diving survey in May 2021. The newly collected specimen is distinguished from a previously known Aquilonastra species in South Korea by having a fissiparous body form with six arms. Results of pairwise genetic distance analysis showed that the new specimen was identical or close to A. anomala from Hawaii (0.0%), Australia (3.1%), and Samoa (3.3%). However, morphological characteristics of the Korean Aquilonastra specimen corresponded with the original description of A. doranae, not that of A. anomala, including the number of inferomarginal spines, the absence of pedicellariae, and the inhabit locality. Thus, this study agrees with the original morphological study of A. doranae and presents this specimen as the first record of A. doranae in South Korea.

  • Silene fissipetala Turcz., which is native to Continental China and Taiwan, was newly found in Chungcheongnam-do, Korea. S. fissipetala is similar to the related taxa S. antirrhina L., S. armeria L., and S. koreana Kom. in that it has glutinous zones. However, S. fissipetala is distinguished from the congeneric species by the presence of laciniate at the petals. The species grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, photographs, voucher specimens and a key to related taxa are provided.

  • 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 sea urchin was collected from Geomundo Island of Jeollanam-do, Korea on July 3, 2009. This specimen was classified as Spatangus luetkeni A. Agassiz 1872 belonging to the family Spatangidae of order Spatangoida based on the morphological characteristics. This genus and species are newly recorded in Korea. It is distinct morphological characters that test is thick and strong, six to eight primary tubercles are in 1 and 4 interambulacra, sternum is equipped with little keel, and color in alcohol is dark violet. This species inhabits tropical waters and usually distributes over the West Pacific from southern Japan to New Zealand.

  • Thirty-six species of the tribe Tortricini (Tortricidae) in Northeast China are listed with available information. Among them, two species, Acleris hastina (Linnaeus) and A. laiordairana (Duponchel), are reported for the first time from China. Croesia crataegi (Kuznetsov) is newly recorded from Northeast China. Available information, including host plant, distributional range, and biological record, are enumerated.

  • To find unrecorded diatom species in the Nakdong River Estuary and Yeongil Bay, bottom sediments in the estuary, and seagrasses in the bay were collected from 12 sampling sites. Eighteen species and four genera are added to the national flora of diatom as newly recorded one. In the Nakdong River Estuary, twelve species are new records to Korea, Martyana atomus (Hustedt) Snoeijs, Pseudostaurosira perminuta (Grunow) Sabbe & Vyverman, Trachysphenia acuminata M. Peragallo, Trachysphenia australis Petit, Fallacia clipeiformis ($K{\ddot{o}}nig$) D.G. Mann, Amphora graeffeana Hendey, Amphora jostesorum Witkowski, Metzeltin & Lange-Bertalot, Amphora ostrearia var. vitrea (Cleve) Cleve, Amphora wisei (Salah) Simonsen, Halamphora eunotia (Cleve) Levkov, Halamphora lineata (Gregory) Levkov, Nitzschia littorea Grunow. In Yeongil Bay, four species are added as new, Licmophora gracilis var. anglica ($K{\ddot{u}}tzing$) H. Peragallo & M. Peragallo, Tabularia investiens (W. Smith) Williams & Round, Nitzschia composita Giffen, Nagumoea neritica Witkowski & Kociolek. Two species occurred simultaneously in both regions, Fragilaria cassubica Witkowski & Lange-Bertalot and Hyalinella lateripunctata Witkowski et al.

  • Asteroid specimens of the genus Diplopteraster were collected by trawling nets at a depth of 93 m on 05 November 2016 from the Korea Strait ($33^{\circ}41^{\prime}N$, $127^{\circ}26^{\prime}E$). The specimens were identified as Diplopteraster multipes(M. Sars, 1866), which belongs to the family Pterasteridae, order Velatida. This species is similar to other Diplopteraster species in its pentagonal stellate shape, but is distinguished by having each paxilla composed of a protruded spine, more than eight spiracles, and regularly reticulated muscular bands. It is not commonly found in shallow water. This is the first report of the genus Diplopteraster and D. multipes in Korea.

  • Dinoflagellate species composition has changed around Jeju Island as well as in Korean waters due to global warming and climate changes. An investigation was conducted to monitor changes in planktonic dinoflagellates around Jeju Island from June 2006 to September 2009. A total of 86 species belonging to 14 families and 15 genera were identified, of which 34 species were newly recorded in Korean waters. Among the newly recorded species, >20 were confirmed as tropical species. Thus, the occurrence of such tropical dinoflagellates could be an indicator to monitor of environmental changes including global warming around Jeju Island and in Korean waters.
