  • Eight new species of the genus Acanthomolgus are described as external associates of octocorallian corals from Korea. As diagnostic features of these new species, A. taenichaetatus n. sp. has ribbon-like distal caudal setae; A. jei n. sp. and A. crassae n. sp. have no inner proximal expansion on the exopodal segment of female leg 5, and the former species has only three setae on the maxillule (vs. four setae in other seven species). Acanthomolgus notialis n. sp. is similar to A. oporinus n. sp. in having a rounded inner proximal expansion on the exopodal segment of female leg 5, but the latter species is distinguished from the former by having longer caudal rami which are about 1.5 times longer than wide, by having a longer inner seta of the maxilla which is three quarters as long as distal lash, and by having unequal setae on the basis of maxilliped. Acanthomolgus dokdoicus n. sp., A. rugosus n. sp. and A. triplus n. sp. appear to be similar to one another in having an ear-like inner proximal expansion on the exopodal segment of female leg 5, but the genital double-somite of the female is distinctly longer than wide in A. rugosus n. sp. (wider than long in other two species), and the third endopodal segment of the antenna is distinctly shorter than the first endopodal segment in A. triplus n. sp. (vice versa in other two species). This is the first record on the genus Acanthomolgus in the temperate West Pacific.

  • Four new nemourid species, Amphinemura rai n. sp., Amphinemura baei n. sp., Protonemura villosa n. sp., and Nemoura espera n. sp. are described and illustrated. Amphinemura rai n. sp. closely resembles Amphinemura tragula (Kimmins) externally, but differs from Amphinemura tragula by the projections on male terminalia and the shape of the female subgenital plate. Amphinemura baei n. sp. is similar to A. bulla Shimizu in body color, size, and structure of male and female terminalia, but distinguished by the ventral sclerites of epiproct, the knobs on the sides of the epiproct, and the shape of paraprocts. Protonemura villosa n. sp. is similar to p. hotakana Ueno in body color, size, and the structure of terminalia, but distinguished by the epiproctal flagellum and ventral sclerite, the shape of the tenth tergum. Finally, Nemoura espera n.sp. is close to Nemoura alabeli Zhilt-zova In appearance, but differs by the shape and location of the ventral and dorsal sclerites of the epiproct.

  • Six phytal harpacticoid species of the genus porcellidium are recorded from 22 algal species in the eastern (Sea of Japan) and southern (Korea Strait) coast of Korea. Among these six species, Porcellidium ofunatense Harris and Iwasaki and Porcellidium gamoi(Harris and Iwasaki) are recorded as new to Korean fauna. Other four species are described as new to science: Porcellidium bipartitum n. sp. found from a single algal species, Procellidium wandoensis n. sp. from ten algal species, Porcellidium acutum n. sp. from five algal species, and Porcellidium brevlcacum n. sp. from two algal species. It is found that the associations between the species of Porcellidium and macroalgae reveal weak specificities.

  • Adult chironomids were collected by various methods, such as light traps, sweeping on grasses, aspiration of light-attracted adults, and sweeping of swarming males with insect nets at various localities. All collected specimens were slide-mounted and identified. I report eight species new to science: Chironomus jangchungensis n. sp., Demicryptochironomus paracamptolabis n. sp., Demicryptochironomus wontongensis n. sp., Microtendipes paratamagouti n. sp., Polypedilum macrohemisphere n. sp., Eukiefferiella busanensis n. sp., Psectrocladius paratogaminimus n. sp., and Pseudosmittia seosania n. sp. I also report four species for the first time in Korea: Chironomus fujiprimus Sasa, Pentapedilum convexum Johannsen, Tanytarsus smolandicus Brundin, and Tanytarsus oyamai Sasa. All species are fully described with illustrations. This is the first report of the genera Eukiefferiella and Pseudosmittia in Korea.

The new ones are Neanura kentingensis n.sp., Womersleya formosana n.sp., Crossodinthina montana n.sp., Vitronura tubercula sp., Lobella nana n.sp., and 2 new records are Pseudachorucina nepalica Yosii, 1966 and Lobella perfusa Denis., 1934. The Neanuridae fauna of Taiwan accordingly is listed as 13 species in 7 genera. The biogeographic affinities with the Japan, Vietnam and adjacent countries are discussed.

  • Eight new species of two genera Dysidea and Euryspongia (Demospongiae: Dictyoceratida: Dysideidae) are described from Gageodo, Ulleungdo, Geomundo, and Jejudo Islands, Korea. Four new species of the genus Dysidea are differentiated by the fibre structure, cored detritus, and fibre arrangement. Dysidea mureungensis n. sp. is characterized by the honeycomb shape of surface and no distinction between primary and secondary fibres. Dysidea glavea n. sp. differs by large sands cored in fibres and that the membrane easily separates from fibres. Dysidea geomunensis n. sp. has fibres that are thinner than those of D. glavea n. sp.. Dysidea corallina n. sp. is characterized by folded fan shape and the arrangement of secondary fibres. Four new species of the genus Euryspongia are differentiated by the fibre structure, cored detritus, shape of sponge, and fibre arrangement. Euryspongia radicula n. sp. is very different from other species by having regularly arranged fibres. Euryspongia spina n. sp. has a fence-like skeletal structure. Bridged type secondary fibres are arranged near the surface and web types are at the base of fibres. Euryspongia flabellum n. sp. has a very unique wide, thin leaf-like shape. String-like primary fibres of E. linea n. sp. are very unique and cored with large sized sands.

  • Ten species of copepods, including nine new species, associated with compound ascidians are recorded from Korean waters. Nine new species can be characterized by their major diagnostic features, as follows: Botryllophilus pentamerus n. sp. by having a five-annulated abdomen; B. paucisetatus n. sp. by the presence of four and three setae on the exopods of right and left leg 1, respectively; Haplostoma quadridens n. sp. by the presence of four lobes on the labrum and one seta plus four spines on the exopods of legs 1-4; H. paucidens n. sp. by the presence of only two spines on the distal segment of the antenna; Enterocola horridus n. sp. by having five setae on the antenna, no seta on the caudal ramus, and two setae on leg 5; E. longicaudatus n. sp. by having long caudal rami which are more than three times as long as wide; Thoracodelphys bisetata n. sp. by the presence of only two setae on the basis of the maxillule; T. cerasta n. sp. by the presence of a large, horn-like process on the distal margin of the basis of leg 2; and Unimeria hirsuta n. sp. by having three setae on the terminal segment of the maxilla. Zygomolgus didemni (Gotto, 1956) previously known only from European waters is reported from Korean waters, with a redescription and illustrations.
