Four new species of the genera Masirana Komatsu, 1942 and Longileptoneta n. gen. (Araneae, Leptonetidae) are described from Gyeongsangbuk-do and Chungcheongbuk-do, Korea, under the names Longileptoneta songniensis n. sp., Masirana bonghwaensis n. sp., M. ilweolensis n. sp., and M. flabelli n. sp. A new genus, Longileptoneta n. gen., is also described.

Two species, Plectiscus impurator Gravenhorst and Stenomacrus laticollis(Holmgren), of the subfamily Orthocentrinae are newly recognized from South Korea. This subfamily Orthocentrinae was represented in South Korea as 17 species belonging to four genera until now. In this paper, two additional species belonging to two genera are recorded for the first time from South Korea. Diagnoses of genera and two unrecorded species, illustrations of diagnostic characters are provided.

Two new species of the genus Psammocinia (Dictyoceratida, Irciniidae), P. conulosa n. sp. and P. ulleungensis n. sp., are described from Namhaedo Island and Ulleungdo Island, Korea. Psammocinia conulosa n. sp. seems to be close to both P. amodes Cook and Bergquist, 1998 and P. hawere Cook and Bergquist, 1996 on the basis of the skeletal structure. However, these three species are clearly separated by the following differences: Shape of P. amodes is spatulate and thin, with a broad blade narrowing to a semi-cylindrical stalk; P. hawere forms cups with a shallow excavated bowl, and attached to the substratum by a narrow base. The whole surface of the new species is very finely conulose. Psammocinia ulleungensis n. sp. is similar to P. gageoensis Sim and Lee, 2001 in shape, but this species is easily distinguished from P. gageoensis by the simple skeletal structure.

A new species of Tanaidacea is described from the eastern coast of Korea, under the name of Apseudomorpha magna in the family Metapseudidae. The new species can be distinguished from its congeners by the following combination of characters: pleonites 2 and 5 and pleotelson have a large lateral seta; pleopods are biramous, in five pairs, each bearing a two-segmented exopod and a single-segmented endopod; the maxillular palp is two-segmented, with five setae on its distal segment; the pleotelson has a large seta on each anterolateral process; and the mandibular palp has 2, 7, and 13 setae on the first to third segments, respectively.

A new marine gastrotrich species, Ptychostomella jejuensis n. sp. belonging to the family Thaumastodermatidae, is described on the basis of the specimens from subtidal sand bottom at about 6-7 m depth of Jeju Island, South Korea. Ptychostomella jejuensis n. sp. is distinguished from its congeneric species with smooth cuticular armature by the character combination: (1) small body up to about 160 ${\mu}m$ in length; (2) presence of knob-like cephalic tentacles; (3) absence of dorsal and ventral adhesive tubes; (4) bifid pedicles; (5) pyriform copulatory organ. Under scanning electron microscopy, numerous epidermal gland openings were observed in the new species, characteristically flanking a bristle. Taxonomic accounts on the affinities, some brief remarks on the epidermal gland openings and the cooccurrence with P. orientalis Lee and Chang, 2003 are also presented with detailed illustrations and scanning electron photomicrographs.

Gitanopsis koreana, new species collected at Ganggu and Sadong in Korea is described and illustrated. This species is very close to G. robastodentes Hirayama, 1983 from west Kyushu, Japan. But, this new species is distinguished from G. robastodentes by the shorter ventrodistal extension of article 2 of gnathopod 2 and the shorter telson.

A new marine sponge, Antho (Acarnia) seogwipoensis n. sp., of the family Microcionidae, was collected from Seogwipo-si, Jeju-do, Korea, about 100 m in depth using a gill net on 1969. The genus Antho Gray, 1867 including Demospongiae, Poecilosclerida, Microcionidae, is a large group of sponges. About 100 species in Antho were reported from worldwide. The genus Antho contains five subgenera: Antho, Acarnia, Isopenectya, Jia, and Plocamia. Among them, about 30 species in Acarnia were described in world sponge. A new sponge's body shape is branching, size up to 124 mm wide, 213 mm high, 3-8 mm thick in branch and 7-9 mm thick in stalk. Antho (Acarnia) seogwipoensis n. sp. is similar to A. (A.) novizelanicum Ridley and Duncan, 1881 based on their spicules type and skeletal structure, but differs in the spicules dimension and growth form. This new species is branched growth form and have three kinds of toxa.

Two new species of the genus Doridicola are described as associates of opisthobranch mollusks from Korean intertidal waters: Doridicola virguatus n. sp. associated with the notaspidean Pleurobranchaea japonica Thiele and D. portincola n. sp. associated with the nudibranch Hoplodoris armata (Baba). This is the first record for the copepod associates of opisthobranch mollusks from Korea.
