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.

The subfamily Pimplinae is one of the largest groups of the family Ichneumonidae, currently 1,737 species in 77 genera worldwide. In Korea, 120 species in 33 genera have been recorded. The South Korean species of the subfamily Pimplinae Wesmael, 1845 (Hymenoptera: Ichneumonidae) are the focus of this study. Here, six species are newly added in the South Korean fauna: Aravenator kamijoi Momoi, Chablisea varicolor Liu, He & Chen, Clistopyga arctica Kusigemati, Liotryphon cydiae (Perkins), L. strobilellae (Linnaeus), and Zaglyptus semirufus marginatus Kasparyan. Of these new taxa, two genera (Aravenato and, Chablisea) belonging to the tribe Ephialtini are also newly recorded from South Korea. We present a key to species of South Korean Clistopyga, Liotryphon, and Zaglyptus, diagnosis, photographs, and distribution. As a result of this study, the Korean fauna of Pimplinae is now known to consist of 126 species in 35 genera. All Pimplinae specimens are kept in the collections of the Geolim Entomological Institute (GEI), Daegu, South Korea.

The family Ameiridae Boeck, 1865 (Copepoda; Harpacticoida) consists of about 380 species in 47 genera, but only 10 species have been reported in Korea. A benthic ameirid species was collected from the East Sea of Korea. Specimens were identified as members of the genus Ameiropsis Sars G.O., 1907, and this is the first record of the genus Ameiropsis in the Pacific Ocean. Ameiropsis gyeongjuensis sp. nov. is morphologically similar to A. mixta Sars G.O., 1907 and A. longicornis Sars G.O., 1907 from Norway. However, the new species is clearly distinguishable from the others based on the following morphological characteristics: the proximal segment of antennary exopod with a bulge in the middle, and with one pinnate seta; the distal segment of antennary exopod with a thickened, blade-shaped outer seta; and female P5 baseoendopod with five setae and exopod with six setae. An identification key to species is provided for the 11 valid species of the genus Ameiropsis.

Ciliates are unicellular eukaryotes and one of the most abundant and speciose protistan groups. However, their diversity is underestimated, and many new species are waiting for our discovery. During several field surveys conducted from 2018 to 2021 to document indigenous Korean ciliates, 10 unrecorded ciliate species were collected and investigated from freshwater, marine, and semiterrestrial habitats. The morphology of these species was studied based on observation of living and protargol-stained specimens. These species belong to five classes as follows: 1) class Heterotrichea - Peritromus faurei; 2) class Spirotrichea - Heterotachysoma dragescoi, Pseudokeronopsis parasongi, and Certesia quadrinucleata; 3) class Nassophorea - Chilodontopsis depressa; 4) class Prostomatea - Plagiocampa rouxi and Urotricha furcata; and 5) class Oligohymenophorea - Metanophrys similis, Uronema gallicum, and Protocyclidium citrullus. Also, we provide a brief diagnosis, photomicrographs, and information of the locality for each species. Further, we compare each species with the most recent description and with similar congeners.

The taxonomic revision was made on the tribe Harpalini (Coleoptera: Carabidae) in Korea. The Korean species are arranged after Kryzhanovskij et al. (1995) system with minor emendation. This present list is an attempt to bring together the available literature and collection-based information on fauna or taxa recorded from Korea (including some collections from the northern part of the Korean Peninsula, now North Korea). Materials examined for each species, an annotative checklist of Korean Carabidae, and the practical key to tribes and genera are provided. As a result, a total 86 species (and subspecies) belonging to 13 genera are recognized from the Korean Peninsula, of which one species (Harpalus egorovi) is new to South Korea. Distribution of two species, Harpalus tardus and H. tibeticus hsifanicus, are very doubtful in the Korean Peninsula. Besides, numerous new distribution records are given as based on materials deposited in various Universities and private collections.

Two cumaceans species, Eocuma amakusense $Gam{\hat{o}}$, 1967 and E. latum Calman, 1907, belonging to the family Bodotriidae are collected from the southern sea in Korea, and are redescribed. At the present, just one species belonging to the genus Eocuma, E. cf. hilgendorfi Marcusen, 1894 has been reported in Korea. Herein we add two Eocuma species to the Korean cumacean fauna and described them with full illustration contained new information of mouthparts. A key to the Korean Eocuma species is also provided.

Amynthas tralfamadore sp. nov. is described from the Mt Halla, Jeju Island biosphere exhibition housed at NIBR Incheon. This species' taxonomy is problematical since it is similar to Amynthas masatakae (Beddard, 1892) from Japan, itself previously reported from Korea and at one time associated with Amynthas campestris (Goto & Hatai, 1898) and A. parvicystis (Goto & Hatai, 1899), all three variously implicated in prior A. robustus (Perrier, 1872) along with Amynthas aspergillum (Perrier, 1872). Based on reinspection of the London lectotype of A. masatakae-here designated and sketched for the first time-the current solution is for maintenance of all five taxa separately. A closely-related Japanese species-Metaphire ryunome sp. nov.-is comparable to Korean Metaphire reisuiensis (Kobayashi, 1938) comb. nov. Another specimen was identified as Amynthas micronarius (Goto & Hatai, 1898), a new record for Korea. It matches the newly-designated neotype (Tokyo NMST An446) and an annotated synonymy is provided; however, erstwhile synonyms, Amynthas shimaensis (Goto & Hatai, 1899) and A. yamizoyamensis (Ohfuchi, 1935) combs. novae, are briefly redescribed and provisionally restored to the Japanese list. mtDNA COI-5P barcode analyses support species identifications.

A new species of arbuscular mycorrhizal fungi (Glomeromycota), Acaulospora koreana, was isolated from forest soils in South Korea. This novel fungus was collected from the rhizosphere of Lindera obtusiloba and Styrax obassia in forest and propagated with Sorghum bicolor in pot. Morphological characteristics of spores of A. koreana are rarely distinguished from Acaulospora mellea, which is reported as one of the most abundant mycorrhizal species in Korea. However, molecular evidence of rDNA sequence using improved primers for glomeromycotan fungal identification strongly supported that A. koreana is different from A. mellea but also any other species belonging to the genus Acaulospora. This is the first novel glomeromycatan fungus introduced in South Korea, but it suggests that there is a high possibility for discovering new arbuscular mycorrhizal fungi considering the abundance of plant species and advanced phylogenetic analysis technique.
