Cyanobium is a genus of picoprokaryotic cyanophytes, which includes species worldwide. The present study investigated the morphology, ultrastructure, and molecular phylogeny of the unrecorded genus Cyanobium Rippka & Cohen-Bazire 1983 and species Cyanobium gracile Rippka & Cohen-Bazire 1983. A C. gracile culture from a freshwater sample collected from the Adongji pond was established by single-cell isolation. Morphological data were analyzed using light and transmission electron microscopy. C. gracile lives as solitary cells without gelatinous envelopes and is ovate, oval, or shortly rod-shaped. Thylakoids are laid along the cell walls, with three thylakoid membranes parallel to each other. Nucleoplasm was observed in the center of the cell. Molecular phylogeny performed with data from 16S small subunit ribosomal DNA gene (SSU rDNA) sequences showed that the three strains of C. gracile, including the type strain (PCC6307) and a newly recorded strain (Adong101619), formed a distinct clade with a high supporting value (maximum-likelihood=100, pp=1.00). Based on morphology and molecular data, we report the newly recorded C. gracile in Korea.

We reviewed eight South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869. Among them, the Genus Scambus Hartig, 1838 is a moderately large group that includes 152 species worldwide. The South Korean genus Scambus Hartig, 1838 only includes one species, Scambus calobatus (Gravenhorst, 1829). The Tromatobia $F{\ddot{o}}rster$, 1869 group is a relatively small genus, including 33 worldwide species. This group is recorded for the first time from South Korea. Also, we report seven newly recorded species: Scambus nigricans (Thomson, 1877), Scambus vesicarius (Ratzeburg, 1844), Tromatobia flavistellata Uchida and Momoi, 1957, Tromatobia nipponica Uchida, 1928, Tromatobia ornata (Gravenhorst, 1829), Tromatobia ovivora (Boheman, 1821), and Tromatobia variabilis (Holmgren, 1856). A key to South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869, diagnoses and illustrations are provided.

맵시벌科 (Ichneumonidae)는 外部形態形質에 있어서 매우 유사한 점이 많아서 種을 同定하거나 硏究하는데 어려움이 많다. 著者들은 走査電子顯微鏡을 利用하여 지금까지 기재되어 있지 않거나 기재가 불충분한 形質들을 찾아서 재기재하였으며, 韓國産 맵시벌科中 Gnues Habronyx (장수자루맵시벌속), Genus Therion (가락지자루맵시벌속)과 Genus Heteropelma (긴가락지자루맵시벌속)을 정리한 결과 未記錄 1종 (Habronyx (Camposcopus) Sonani (Uchida), 1958)을 추가하게 되었다.

A taxonomic study of the genus Delta de Saussure, 1855 from Vietnam is presented. A total of four species are recorded: D. campaniforme campaniforme (Fabricius, 1775), D. conoideum (Gmelin, 1790), D. esuriens esuriens (Fabricius, 1787), and D. pyriforme pyriforme (Fabricius, 1775). Of these, D. campaniforme campaniforme was first recorded from Vietnam by de Saussure et al., 1904, under the name Eumenes esuriens and is now reconfirmed to occur in Vietnam after more than 100 years, and D. conoideum is newly recorded from Vietnam. A key to species based on morphological characters is given with illustrations, and distributional records in Vietnam are also provided.

Flies of the genus Lispe Latreille are widely distributed worldwide, with over 150 species recorded, of which 57 are distributed in the Palearctic region. Larvae mainly live in sandy or mudy environments, and adults are found nearby. Both adults and larvae are predators of a variety of small aquatic insects. Until now, a total of six species have been recorded in the Korean fauna. In the course of taxonomic research of Korean house flies, the authors discovered two new unrecorded species, L. leucospila (Wiedemann, 1830) and L. pygmaea Fallén, 1825. The diagnoses and illustrations of these species are provided with the key to the Korean Lispe species.

Our study aimed to investigate the diversity of tintinnid species in Korea by collecting samples from coastal waters. As a result, we identified and redescribed three newly recorded species of the genus Tintinnopsis Stein, 1867 and one previously recorded species of the genus Antetintinnopsis Wang et al., 2021 in Korea. The loricae morphology and molecular phylogeny based on the 18S rDNA sequences of these four were analyzed. Tintinnopsis kiaochowensis Yin, 1956 is characterized by having an irregular collar with spiral turns and an obconical-shaped bowl. Tintinnopsis orientalis Kofoid and Campbell, 1929 is characterized by the inverted bell-shaped lorica with size of 121-140×86-94 ㎛. Tintinnopsis parvula Jörgensen, 1912 is characterized by its narrower collar than bowl and acute angle of the bowl (39-75°). The recorded species, Antetintinnopsis gracilis (Kofoid and Campbell, 1929) Wang et al., 2021 is characterized by a cylindrical collar narrower than the bowl width and with a size of 98-131×37-46 ㎛.

The burrowing-cricket genus Velarifictorus Randell, 1964 is reviewed in Korea, comparing with morphologically resembled genus Lepidogryllus Otte and Alexander, 1983 for the first time. First, Velarifictorus aspersus borealis Gorochov, 1985 is confirmed from only restricted area of southern regions in Gyeongsangnam-do and Jeollanam-do. Second, Velarifictorus micado (Saussure, 1877) is confirmed from nearly all around the Korean peninsula including North Korea. Third, the previously not recorded Velarifictorus ornatus (Shiraki, 1911) is newly recognized from South Korea. Relating to the genus Velarifictorus, the resembled genus Lepidogryllus Otte and Alexander, 1983 and its species Lepidogryllus siamensis (Chopard, 1961) com. & stat. nov. is studied and compared with Velarifictorus members. A key, descriptions, tables, photographs, figures, oscillograms and spectrograms of calling sounds are provided to aid identification between the four similar species.

Some asteroid specimens were collected at a depth of 150 m near Moseulpo in Jeju Island, Korea using fishing nets on October 2014. The specimens were identified as Henricia pacifica Hayashi, 1940 belonging to the family Echinasteridae of order Spinulosida. In the Korean fauna, seven species of genus Henricia were reported of which two species, H. nipponica and H. ohshimai, were distributed in Jeju Island. The morphological characteristics of this species were re-described with illustrations.
