  • 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.

  • Two marine ulvalean species (Chlorophyta) were collected from the southern and eastern coasts of Korea. One is morphologically characterized by usually unbranched or little branched ribbon-shaped thalli, fronds with spirally twisted basal portions and usually undulate margins and 1 (-2) pyrenoids per cell. The other has irregularly shaped thalli, undulate and dentate margins in the fronds, small macroscopic denticulations along the margin and (1-) 2-3 pyrenoids per cell. In phylogenetic tree based on molecular data, the two species nest in the same clade with Ulva flexuosa and U. rigida, respectively. These two Korean entities are identified as U. flexuosa and U. rigida, respectively, based on morphological and molecular analyses. This is the first record of Ulva flexuosa and U. rigida in Korea.

  • The species of the genus Chlorociboria Seaver are very common on the forest floor, and can be easily distinguished by small and numerous blue-green fruitbody, especially the blue substrate dyed with xylindein produced by this group. This genus has rather high species diversity in the Southern Hemisphere, while a little attention was paid to this group in East Asia area. During a field survey in South Korea, several Chlorociboria specimens were collected. Based on morphological and phylogenetic analyses, three species of Chlorociboria were reported, including one new record in South Korea and one new record in Jeju Island. The key to the species of Chlorociboria from South Korea is provided.

Identification keys, redescriptions and illustrations of all species and both sexes, if they were found in Korea, are presented. Genus Achyrolimonia is new record for the Korean peninsula, genera Dicranoptycha and Helius are new records for South Korea, species Helius (Helius) obliteratus (Alexander, 1920) is new record for the Korean peninsula and new record for the continent. Illustrations of females of D. diacantha Alexander, 1938 and H. gracillimus Alexander, 1938 are provided and female of D. prolongata Alexander, 1938 is described and illustrated for the first time.

  • Psenes arafurensis, belonging to the family Nomeidae, is described based on four specimens (184.8-199.0 mm in standard length) collected from Korea. The species is most similar to the congeneric species P. maculatus and P. pellucidus, but differs from them in the number of lateral-line scales. (44-47 in P. arafurensis vs 67-70 in P. maculatus and 120 in P. pellucidus) and the number of vertebrae (31 in P. arafurensis vs 34-38 in P. maculatus and 40-42 in P. pellucidus). The present study is a new record of P. arafurensis with voucher specimens from Korean waters.

  • Oncaea prendeli Shmeleva, 1966 is redescribed here based on a specimen collected using a fine-mesh net in the epipelagic layer in the south sea of Jeju Island, Korea. The Korean specimen is generally similar to Mediterranean specimens in terms of morphological characteristics, but it shows a few minor differences in a slightly larger length-to-width ratio for the distal endopod segment of the antenna, a relatively shorter caudal seta IV, and additional ornamentation on the maxillule and maxilla. This species is distinguishable from the most similar congeneric species, O. tregoubovi Shmeleva, 1968, and three species of the genus Spinoncaea Böttger-Schnack, 2003 by the distal and lateral armature of the antenna, ornamentation on the female maxilliped, spine number on the endopod of leg 2, and proportional length of setae on the caudal ramus. Moreover, spine lengths on the exopods of legs 2-4 are proposed as new morphological characters for the identification of congeners. This is the first record of O. prendeli in Korean waters.

  • Only four species of leuconids have been recorded in Korea, all belonging to the genera Eudorella Norman, 1867 and Nippoleucon Watling, 1991. In this study, Pseudoleucon japonicus Gamô, 1964 belonging to family Leuconidae Sars, 1878 is newly recorded for Korean cumacean fauna. Also, for the first time, the male of the species is fully described and illustrated. The specimens were collected from the exclusive economic zone (EEZ) in the western sea (Yellow Sea) of Korea, with a rectangular dredge during 2007-2008. This species is characterized by the following features: the carapace has strong serrations on the antero-lateral margin and a pair of short oblique ridges on the side surface; the ridges begin near the end of frontal lobe and merge with the dorsal median carina; the appendages, such as antenna 1, pereopod 2 and uropod have a lot of simple setae decorated with a bundle of hairs at the end. The present study represents the first record on the genus Pseudoleucon Zimmer, 1903 from Korea.

  • Two newly recorded species of melitid amphipod, Abludomelita japonica (Nagata, 1965) and A. okhotensis Labay, 2016 belonging to the family Melitidae Bousfield, 1973 were collected from Korean waters. To date, only two genera, Dulichiella Stout, 1912 and Melita Leach, 1814, of the 28 genera of Melitidae have been recorded in Korea, so this is the first record of the genus Abludomelita from Korea. The genus Abludomelita Karaman, 1981 is morphologically similar to Melita Leach, 1814, however they are distinguished by having oblique row of setae on inner lobe of maxilla 2. Both newly recorded species are fully illustrated and compared with related species.

  • Three species of Choreutidae, Choreutis atrosignata (Christoph, 1888), Choreutis japonica (Zeller, 1877), and Litobrenthia japonica (Issiki, 1930), are reported for the first time from Korea. The records of C. atrosignata and C. japonica are based on two females from Yeongwol, Gangwon Province and from the Island Chujado, Jeju Province, respectively. The latter species was obtained from two larvae collected on the leaves of Ficus erecta (Moraceae). Photographs and data of rearing the larvae are provided. The record of L. japonica was based on two specimens collected from the Islands, Bogildo and Wando, Jeollanam Province. The present data of L. japonica represent the first record of the subfamily Brenthiinae and the genus Litobrenthia from Korea. Distributions of two species C. japonica and L. japonica, previously known only from Japan, now extends to Korea. Habitus and genitalia of the species treated here are briefly described and illustrated, if possible. To sum up, the Korean Choreutidae comprises four genera and 10 species, nine in Choreutinae and one in Brenthiinae.

  • A newly recorded species, Aora pseudotypica Hirayama, 1984, belonging to the family Aoridae Stebbing, 1899 was collected from Geomundo and Jejudo Islands in South Korea. This species is characterized by having large triangular process on basis of male gnathopod 1. It is morphologically similar to A. typica Krøyer, 1845, but distinguishable by the lack of a large rounded process on the anterior margins of basis and ischium on male gnathopod 1 and having small distal segment on outer ramus of uropod 3. To date, only two genera, Aoroides Walker, 1898 and Grandidierella Coutière, 1904, of the family Aoridae have been recorded in Korea, so this is the first record of the genus Aora from Korea.
