An ennomine species, Paradarisa chloauges Prout, 1927 is newly recorded from Korea. Adults were collected at the south aspect of Mt. Hallasan, Jejudo. Paradarisa chloauges can be distinguished by grayish or dark greenish foreand hindwings, blackish basal, ante- and postmedial lines with a blackish discal dot on the forewing and transverse antemedial line, as well as a strongly dentate postmedial line and a thick, dark brownish tinged subterminal line on the hindwing. Paradarisa chloauges is externally very similar to P. consonaria, but can be distinguished by the larger wingspan and flying time. The male genitalia of P. chloauges are similar to those of P. consonaria, but can be distinguished by the long sacculus and two harpe processes on the valva and the large spinular cornuti on the vesical. The female genitalia of P. chloauges are similar to those of P. consonaria, but can be distinguished by the large bagshaped corpus bursae. To date, two species of the genus Paradarisa have been recorded in Korea.

The species Orchomenella littoralis Nagata, 1965 belong to the family Tryphosidae Lowry & Stoddart, 1997. Previously this species was only known from a single record identified in Japanese waters, and newly recorded from Baengnyeongdo-Island, on the west coast of Korea. The species is similar to Orchomene breviceps Hirayama, 1986 in carrying posteroventral teeth on epimeron 3. However, O. littoralis is characterized by the presence of 4-7 posteroventral teeth of epimeron 3, a round posterodistal lobe of coxa 4, and elongated antenna 2 in male. The species is described and fully illustrated in the present study. Also, a key to Korean Orchomenella species is provided.

The brittle star, Amphistigma minuta H.L. Clark, 1938, was collected from Munseom Island, Jeju-do, Korea, by SCUBA diving. This species has distinct morphological features, as follows: a small disk with large papillae on the disk margin; slender arms and four arm spines at proximal; and oral parts the same as those of the genus Amphipholis. Additionally, we obtained partial sequences of the cytochrome c oxidase subunit I gene (COI) (513 bp) and compared them with sequences from Australian A. minuta and 13 other species of Amphiuridae. As a result, intraspecific pairwise distance was 0.4% between two Korean individuals and intraspecific distance between the Australian and the Korean populations was 2.6-2.8%, which indicates they should be considered as the same species. Ultimately, 15 species of the family Amphiuridae have currently been recorded in Korea, including A. minuta.

Two species of Scopula, S. asthena Inoue, 1943 and S. tenuisocius Inoue, 1942, were newly recorded from Korea. Scopula asthena can be distinguished by the bipectinate male antennae and whitish wings with four blackish dots on each wing. This species is similar to S. superior (Butler, 1878) but differs in the large blackish discal dots on both wings. Scopula tenuisocius can be distinguished by its whitish forewing with light grayish, dentate antemedial line, short-line shaped discal dot and line light grayish, weakly rounded, dentate postmedial line, and whitish hindwing with a blackish discal dot and light grayish, undulating medial lines. Scopula tenuisocius is similar to S. floslactata (Haworth, 1809) but the species can be distinguished by the thinner and blackish subterminal line of the forewing that appears minutely dentate along the line. To date, 41 species of the genus Scopula are known in Korea.

The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.

A noctuid moth, Condica dolorosa (Walker, 1865) was newly recorded from Korea. Condica dolorosa can be distinguished by the blackish forewing that shows irregular yellowish dots on the ante- and postmedian and a large pale yellowish dot at dorsum, and yellowish white discal dot with renal marking, and the basally whitish hindwing. Externally, Condica dolorosa is similar to C. cyclicoides but can be distinguished by the dark ochreous dots on dorsum of the forewing. The female genitalia of C. dolorosa are similar to those of C. cyclicoides but can be distinguished by the large bowl-shaped ostium bursae with a midventral invagination and the long ductus bursae. To date, five species of the genus Condica have been recorded in Korea.

Lobohalacarus weberi (Romijn and Viets, 1924) is added to the halacarid fauna of Korea as the third member of freshwater halacarid species. Both the genus and species are newly recorded from Korea. Halacarid mites were collected from two hillside wells and a streamside hyporheic zone in the southeastern region of South Korea. Lobohalacarus weberi is characterized by a well-developed frontal spine-like process, seven dorsal setae, the fourth segment of palp with a short distal and three long proximal setae, and tibiae of legs II to IV with two, one, two pectinate setae, respectively. A few minor individual variabilities were observed in the number of perigenital seta and genital acetabula, the setal armature on genua of legs, and the shape of spinule row on lateral claws.

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.

(A.) pictipennis Reitter, were reported up to date, and latter species is newly recorded in South Korea in this paper. A redescription, habitus photograph, and illustrations of diagnostic characters of the species are provided, with a key to species of the subgenus Abstrulia.
