Six species of the phytoseiid mites were recorded from the pear field of Naju District in Korea: Amblyseius womersleyi, A. eharai, A. orientalis, A. makuwa, A. bakeri and Proprioseiopsis nemotoi. Of these, A. bakeri and p. nemotoi were previously unrecorded in this field, and genus Proprioseiopsis is recorded for the first time in Korea.

Two species of the family Clavicipitaceae, Cordyceps tricentri Yasuda and Cordyceps sphecocephala (Klotz) Mass. which have not been reported so far in Korea, were collected and identified. These are added to the list of three previously recorded species, Cordyceps sobolifera, C, militaris, and C. nutans.

Research on Korean nematocerous flies (Diptera: Nematocera) was started by the National Institute of Biological Resources in 2012. This publication is a continuation of our previous work. During the season of 2019 insects were collected in Odaesan National Park by the researchers from Korea University. Among these samples, two specimens belonging to the family Hesperinidae, which was previously unrecorded from Korea, were noticed. This family is known from countries bordering Korea (East Siberia and Far East of Russia, Hokkaido Island of Japan), thus occurrence of hesperinid flies was expected on the Korean Peninsula. Only one genus Hesperinus Walker, 1848 with eight species belong to this family. They are developing in decaying wood of deciduous trees. Hesperinus rohdendorfi Krivosheina & Mamaev, 1967, which was known from East Siberia and Far East of Russia is recorded from South Korea. Redescription and photographs of the most important taxonomical details are presented.

Foraminifera are protists that inhabit diverse marine environments and show high abundance and diversity. However, previous studies on foraminifera in Korea mostly focused on geological and paleoecological fields and were conducted in a limited area. Therefore, there is a high possibility for discovering new and unrecorded species. Here we describe three newly recorded foraminiferal species from the southwestern part of Jeju Island during a survey on the meiofaunal community, which belongs to three different genera (Ammobaculites, Cylindroclavulina, Saracenaria), three families (Lituolidae, Vaginulinidae, Valvulinidae), and three orders (Lituolida, Textulariida, Vaginulinida): Ammobaculites formosensis Nakamura, 1937, Cylindroclavulina bradyi (Cushman, 1911), and Saracenaria hannoverana (Franke, 1936). These species have been reported from Chinese region in the East China Sea, however this is the first report from Korean waters. Particularly, Cylindroclavulina bradyi is the first report of the genus Cylindroclavulina in Korean waters. The present study supports the diversity of foraminiferal species in Korea, and the necessity of further surveys in Korean waters.

In 2020, during a survey of cnidarian fauna around Chuja-do locating in the northern part of Jeju-do, Korea, several hydroids were collected from the subtidal zone by SCUBA diving. Through taxonomic examination, one unrecorded species, Hydrodendron stechowi Hirohito, 1995, was found in Korea. It was newly added to the list of Korean hydrozoan fauna. This species was discovered for the first time since its first report as a new species in Japan. Their vivid orange-colored colonies were attached to the sponge on rocky substrate between depths of 15 and 20 m. Thus, a total of five species belonging to genus Hydrodendron, including the species reported in this study, have been reported in Korean waters so far.

Spiradiclis hainanensis H.S. Lo and S. purpureocaerulea H.S. Lo (Rubiaceae) are reported as new additions to the flora of Vietnam. In Vietnam, the genus Spiradiclis has been represented by only two species, S. leptobotrya (Drake) Pit. and S. caespitosa Blume. During our field investigations in the Lao Cai and Ninh Binh Provinces of northern Vietnam, we collected two interesting specimens of Spiradiclis that were earlier known only from China and unknown in Vietnam. Here, we report S. hainanensis and S. purpureocaerulea as previously unrecorded species from Vietnam. Detailed descriptions and color photographs are provided along with a taxonomic key for Spiradiclis species in Vietnam.

The seven unrecorded ciliates were collected from soil samples in Korea. The morphological study of these ciliates was performed based on observation of both living and stained cells: Rigidocortex quadrinucleatus Bharti, Kumar and La Terza, 2017, Rigidohymena tetracirrata (Gellért, 1942) Berger, 2011, Urosoma salmastra (Dragesco and Dragesco-Kernéis, 1986) Berger, 1999, Urosomoida agilis (Engelmann, 1862) Foissner, 1982, Rigidosticha italiensis Bharti, Kumar and La Terza, 2016, Eschaneustyla terricola Foissner, 1982 and Pseudokeronopsis similis (Stokes, 1886) Borror and Wicklow, 1983. Among the seven genera in this study, the genus Rigidosticha Bharti, Kumar and La Terza, 2016 is firstly reported in Korea. In this study, we provide brief descriptions and remarks for the ciliates with photographs.

Two genera with two species of the superfamily Ichneumonoidea, Testudobracon pleuralis Ashmead 1906 and Diadromus subtilicornis Gravenhorst 1829, are reported for the first time from South Korea. Diagnosis, distribution, and illustration are provided.

A taxonomic examination of Zygophylax species collected from the subtidal zone of Seongsan Ilchulbong in the east of Jeju Island and a reexamination of the voucher specimens previously described as Z. biarmata were conducted. Through this study, the species previously reported as Z. biarmata in Korea was redescribed as Z. pacifica, and the specimens from Seongsan Ilchulbong were confirmed to be Z. biarmata. Zygophylax biarmata has two nematothecae on the apophysis of the hydrotheca, a clear distinction between the apophysis and the pedicel of the hydrotheca, and much smaller hydrothecae, whereas Z. pacifica has a single nematotheca on the apophysis of the hydrotheca, no distinction between the apophysis and the pedicel of the hydrotheca, and much larger hydrothecae. As a result of this study, a total of two species belonging to genus Zygophylax have been reported in the hydrozoan fauna of Korea to date.

The family Curtonotidae, known as the Hunchbacked or Quasimodo fly, is a small group of acalyptrate flies belonging to the superfamily Ephydroidea. Until now, a total of 103 species under four genera have been recorded worldwide, mainly distributed in tropical and subtropical areas. Among them, only five species of the genus Curtonotum Macquart, 1843 have been recorded in the Palaearctic region, mainly in the Russian Far East, but there are still no previous reports in the Korean fanua. In this study, we firstly report the family Curtonotidae Duda, 1934 from Korea with Curtonotum maritimum Ozerov, 2007. Additionally, we provide taxonomic information and a key for the Palaearctic Curtonotum species.
