Two species of crabs, Homola orientalis Henderson, 1888 and Pseudomicippe nipponica (Sakai, 1938), are described and illustrated for the first time in Korea. Homola orientalis was collected at 30 m depth by trap from Busan, and P. nipponica was collected on the intertidal region in Seongsanpo, Jejudo Island. Homola orientalis is the first species of its family in the region. The family Homoldae is characterized by a linea homolica on the carapace and they carry camouflage in the form of sponges or cnidarians with subchelate of the fourth ambulatory legs. The Korean brachyuran fauna now comprises 223 species including the new records from this study.

An unrecorded Fissidens species, Fissidens protonemaecola Sakurai (Fissidentaceae, Bryophyta), was newly discovered in Korea during an investigation bryophyte flora. In this study, we examined the morphology of F. protonemaecola in Korea. This species was found in soil along a train through a shaded backslope of Mt. Bukbyeongsan (elev. 80 m) on Geojedo Island and on Mt. Gogeunsan (Oreum; elev. 280 m) on Jejudo Island, Korea. This species has dwarfish bud-like shoots scattered on persistent protonemata. An important feature of the protonemata is a diagnostic character of F. protonemaecola that clearly distinguishes it from other Fissidens species. Its Korean name is given as "Cho-rok-sil-bong-hwang-i-kki," inferred from the characteristic protonemata of the species.

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.

Distribution of Viola inconspicua is newly discovered in Korea. This species was collected from grassy fields and roadsides in Jeju-si and Seogwipo-si, Jejudo Island. V. inconspicua shares several characteristics (i.e., purple or pale purple flowers, triangular leaf blades, winged petioles, and a linear-lanceolate stipules) with the related species V. mandshurica and V. yedoensis. However, V. inconspicua can be easily distinguished from other species by the following characteristics: leaf base (cordate vs. truncate to attenuate), and spur (short, 2-4 mm long vs. longer, 5-8 mm long). Here, we describe and illustrate of V. inconspicua. In addition, the identification key to allied species, photographs in its habitat, distribution, ecology, and phenology are provided as well. The Korean name for the species is given as 'Hwa-sal-ip-je-bi-kkot', considering the shape of its leaves.

Ovigerous crab of Echinoecus nipponicus of subfamily Eumedoninae in Pilumnidae was collected from Seogwipo, Jejudo and hatched in the laboratory. The first zoeal stage of E. nipponicus is reported for the first time in the world and its digital image of live zoeas is provided. The first zoea of E. nipponicus has yellowish red chromatophores which occurring behind eyes, on dorsal spine and on anterior margin of telson, reddish brown chromatophores on abdominal somites 2-5 ventrally, dorsal, rostral, and lateral spines shorter than carapace length, three aesthetascs and two setae on the antennule, two medial setae on the antennal exopod, lateral processes on the abdominal somites 2, 3, and two lateral spine and one dorsomedial spine on the telson.

An epialtid spider crab, Naxioides robillardi (Miers, 1882), is known as widely distributed in Indo-West Pacific region include Japanese waters. Four specimens of epialtid crabs were collected from adjacent waters of Jejudo Island and identified as N. robillardi. This species can be grouped into two forms such as N. robillardi form typical and N. robillardi form mammillata according to morphological features of carapace, gastric spine, and chela. Morphological characters of all Korean specimens well agree with the form mammillata in general. In this paper, morphological diagnosis and illustrations of newly collected N. robillardi are provided. DNA barcode sequence of COI region is also determined for the first time.

This study newly records a deep-sea coral, Flabellum (Ulocyathus) deludens from Korea. The specimens were collected by trawling at a depth of 100 m off Jejudo Island in 2019. The newly recorded species is described and compared with the other similar consubgeneric species in detail based on morphological characteristics, including corallum size, calicular diameter, calicular edge, face angle, edge angle, and septal arrangement. Flabellum(Ulocyathus) deludens is characterized by its solitary, highly compressed, wedge-shaped corallite with a small cylindrical pedicel, radiating inverse chevron-patterned lateral stripes on thecal faces, highly jagged calicular edges, and hexameral septal arrangement in five cycles. As a result of this study, five species in the family Flabellidae have been recorded from Korea.

Eight species and four genera belonging to two families of antipatharians have been reported in Korea. In the present study, the major specimens were collected from the coastal areas of Jejudo Island from 2005 to 2006, and the other ones which have been deposited in the Natural History Museum and the Department of Life Science, Ewha Womans University during the period from 1965 to 2004 were reexamined. As a result of this work, four species, Myriopathes bifaria, M. stechowi, M. ulex and Plumapathes pennacea are new to Korean antipatharian fauna. In this study, total six species including previously recorded species of the family Myriopathidae were described. And the distribution range of Myriopathes lata was turned out to be expanded from southwestern sea to the eastern sea, up to Ulleungdo Is. of Korea. Especially, the sexuality and the gonadal stage of M. lata which are collected during their reproduction period were also determined by means of histological analysis.

Two specimens of pontoniine shrimp, Periclimenes brevicarpalis (Schenkel, 1902), having a symbiotic relationship with sea anemones are reported for the first time in Korea. The specimens were collected by SCUBA diving in Jejudo Island. It has a transparent body with a few large white spots on the carapace, abdomen, telson and uropods. Blue bands are on the cheliped and pereiopods. Five brown eyespots with orange centers are on the telson and uropods. The morphology is described and illustrated with a color image of the living specimens. Two species of Korean Periclimenes, P. ornatus, and P. brevicarpalis, can be distinguished by the position of the anterior dorsolateral spine of the telson. This study extends its previously known range from Japan to Korea. Korean pontoniine now includes six species belonging to five genera of Conchodytes, Cuapetes, Onycocaris, Periclimenaeus, and Periclimenes.

Ten new species of genus Sarcotragus (Demospongiae: Dictyoceratida: Irciniidae) are described from Geomundo Island and Jejudo Island, Korea. All new species of the Sarcotragus are distinguished from the other reported species of Sarcotragus by the skeletal structure, especially fasciculate primary fibres. The characters of genus Sarcotragus have cylindrical primary fascicles filled with wads of filaments or flattened fascicles. All of the primary fibres are not cored with foreign debris. Secondary fibres have slightly fasciculate branch or plastic-like web. They are all not cored with foreign debris. All skeletal fibres are very irregular. The surface is covered with loose or tight filamentous membrane.
