A taxonomic study of Peltigera in South Korea was performed. The phylogenetic analysis based on nr DNA internal transcribed spacer sequences suggests that Peltigera is a well-supported monophyletic group. Important characteristics are the phycobiont type of thallus and the vein type at the lower cortex (wide and flat, or narrow and ridged). The vertical or horizontal arrangement of the apothecia is also important in distinguishing species in this genus. Eleven species of Peltigera were revealed and confirmed, which included one new record, P. elisabethae. A description of each species is presented with morphological, anatomic, and chemical characteristics, and comparisons between similar species are made. A key to the species is also presented.

Previously, 33 species, 18 genera, eight subfamilies of the family Tineidae were reported in Korea. In this study detail a new record to Korea, species, Micrerethista denticulata Davis, 1998 in the subfamily Harmacloninae in Korea. This species is the most widespread species of the genus in southern Asia, ranging from Thailand through Indonesia to southern Japan but absent from New Guinea. Globally, Harmacloninae Davis, 1998 includes 22 species of two genera. The subfamily can be distinguished from the other Tineidae subfamilies by an additional wing locking mechanism, loss of pretarsal arolium and pseudempodial seta, tympanic organ in abdominal sternum II, enlargement of sternal apophyses, and aedeagus with basal midventral keel in male genitalia. The morphological characteristics of this subfamily and species are described, and illustrations of examined species and the key characters for each subfamilies of the family Tineidae from Korea are provided.

A new species of the Cletopsyllidae belonging to the genus Isocletopsyllus Huys and Lee, 1999 is described from the materials collected from subtidal sandy bottoms at Jeju Island and Ulleung Island, Korea. So far, only two species of the genus Isocletopsyllus, viz. I. tertius (Por, 1964) from Israel and I. quartus (Soyer, 1966) from Banyuls-sur-Mer (France) are recorded, both from the Mediterranean Ocean. The new species can be clearly distinguished from its congeners by the combination of the following characters: (1) female antennule with a large process on the outer margin of first segment, (2) caudal rami with a bulbous proximal inner expansion, and shorter than those of other species (about four times long as wide in the new species), (3) second segment of P1 exopod with a short rod-like inner seta, (4) sexual dimorphism presented in the second endopodal segment of male P2, not in exopod of P4, and (6) female P5 with a very long exopod with very short second outer seta. A table comparing the modifications of swimming legs in the family Cletopsyllidae Huys and Lee, 1999 is presented. This is the first record of this family from Korea.

A marine algal species was collected from the southern coast of Korea. This alga is characterized by a large and cartilaginous thallus, a dichotomous branching pattern, compressed axes, rare proliferations near the apex, and cystocarps protruded toward surface. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade as Neodilsea yendoana as a terminal clade of the genus Neodilsea. The genetic distance between both sequences within the clade was calculated as 0.2% considered to be in the intraspecific range within the genus. Based on the morphological and molecular data obtained in the present study, this Korean species is identified as N. yendoana. This is the first record of the genus Neodilsea and N. yendoana in Korea.

A marine ulvalean species (Chlorophyta) was collected from Imgok, which is located on the eastern coast of Korea. This species is morphologically characterized by distromatic, filiform to strap compressed or tubular thallus. Many branches were found near the base, but lacked proliferations. Cells were longitudinally aligned in the younger part of the branch and were disordered in the older part of the branch. A cap-like parietal chloroplast with one or two pyrenoids was contained in each cell. In a phylogenetic tree based on ITS and rbcL sequences, this species was nested in the same clade as Ulva torta and U. clathratioides from Australia, but formed a sister clade to U. torta from Japan. However, the genetic divergence between them was included in an intraspecific variation range within Ulva. This finding suggests that U. clathratioides should be reduced to a synonym of U. torta. Accordingly, the Korean alga was identified as U. torta based on the morphological and molecular data. This investigation is the first record of U. torta in the Korean marine algal flora.

An acaenitine genus, Spilopteron Townes, 1960, is reported for the first time in Korea with S. mucronatus Lee new species. A key to the Korean genera of the tribe Acaenitini Foerster, 1869, description of the a species and photographs of diagnostic characters are provided.

Eight species of Chironomidae (Diptera) which are new to Korea are described with illustrations. They are extremely rare species in Korea, as only one or two specimens have been collected since 1977 throughout the country. Microchironomus tener, Stictochironomus akizukii and Paratendipes nubilus belong to subfamily Chironominae, and the other five species: Diplocladius cultriger, Limnophyes minimus, Metriocnemus fulvofasciatus and Parametriocnemus stylatus belong to subfamily Orthocladiinae.

A taxonomic review of the Korean Lycocerus (Cantharidae, Coleoptera) was presented. Through this study, total of four species were found from Korea including a species new to Korea, Lycocerus striatus. We newly provided a key to the Korean Lycocerus species and the distributional map on each species in this study.

One of bryozoans collected from the subtidal zone of Manjae Island on Aug. 23, 1988 was identified. Parasmittina delicatula (Busk, 1884) turned out to be new to the Korean fauna. Therefore, twelve bryozoan species are reported from Manjae Island so far. Ten species including the present one among them were recorded only from the Pacific Ocean. They consisted of four tropical, three cold temperate and four endemic species to Korea and Japan. It is quite probable that Manjae Island, which is influenced by both warm and cold water currents, seems to be unique and significant area in terms of marine zoogeography.

A single specimen (244.2 mm in standard length) of Satyrichthys welchi was collected from Pohang in the southern East Sea of Korea in March 2021. This species is characterized by the following morphological combination: 4 lip barbels, 3 chin barbels, antrose spines on upper lateral low of posterior bony plate and equal parietal bones. S. welchi was morphologically similar to its congeneric species, S. laticeps, but is clearly distinguished in presence of dusky black spots on dorsal fin (present in S. welchi vs. absent in S. laticeps). We propose a new Korean name "Gi-JeomByeol-Seong-Dae" for the species S. welchi.
