  • Eleven species of water mites belonging to the subfamily Axonopsinae are described from the eastern area of Korea. They were collected mainly in streams and are composed of 3 species of Albaxona(all new), 1 new species of Javalbia., 2 species of Brachypoda(both new), 2 species of woolastookia (both new), 2 species of Ljania (1 is new), and 1 species of Lethaxona(new record). The descriptions are mainly based on the male specimens.

  • Four new species of genus Scalarispongia (Demospongiae: Dictyoceratida: Thorectidae) are described from Jejudo Island, Korea. These new species of Scalarispongia are compared with 14 reported species of the genus by the skeletal structure. Scalarispongia songakensis n. sp. is similar to S. lenis in sponge shape but differs in skeletal structure and meshes are not divided into two sections. The length of secondary fibres between primary fibres of this new species is much longer than S. lenis'. Scalarispongia radicula n. sp. is resembles S. songakensis in sponge shape, but this new species has pseudo-tertiary fibres at the sponge base. Scalarispongia maraensis n. sp. is very similar to S. subjiensis in sponge shape but primary fibres of this new species are not simple because fibres have wide webbing. Scalarispongia massa n. sp. is characterized by the large mass sponge shape and numerous open oscules form a long ling on the ridge of the sponge.

  • Twelve new species of two genera Smenospongia and Cacospongia (Demospongia: Dictyoceratida: Thorectidae) are described from Gageodo Island and Ulleungdo Island, Korea. Of these, ten new species of the Smenospongia are distinguished from the other nine reported species of the genus by the skeletal structure and sponge colour. Primary fibres of the genus Smenospongia are mostly dense, dark colour, and invisible inside of fibres, but they are mostly cored detritus and echinated with spicules. Especially, the end of primary fibres at the surface shows densely cored with spicules. All these new species changed the colour. Two new species of the genus Cacospongia are compared with nine other reported species. In skeletal structure, primary fibres of the genus Cacospongia are light colour, visible inside and more heavily cored with spicules and sands. The skeleton of this genus has large meshes. The colour of the genus Cacospongia does not change.

  • Eleven new species of two genera, Psammocinia and Ircinia (Demospongiae: Dictyoceratida: Irciniidae) are described from Gageo Island, Ulleung Island and Jeju Island, South Korea. The separation of these two genera was made on basis of morphological evidence, especially skeletal structure with foreign debris. Six new species of Psammocinia and five new species of Ircinia were added to known fauna. All skeletal fibres are very irregular.

  • We describe three new species of the Genus Kleidotoma (Figitidae: Eucoilinae) from Korea. They are K. convexitas n. sp., K. debilifovea n. sp. and K. longirudis n. sp. A key to all Korean Kleidotoma species including three new species herein are given. Descriptions and illustrations of diagnostic characters of three new species are also provided.

  • A new species, Miscanthus wangpicheonensis of section Kariyasua, is described and illustrated from the morphological characteristics based on a type specimen collected from Gyeongsangbuk-do. This new species is similar to Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. The characters which distinguish the above two species are short leaves and racemes, callus hairs 1-1.5-times longer than spikelet, and well-developed awns of spikelet. The specific epithet, "wangpicheonensis", is based on the name of the locality where the new species is found. We assume this new species originated from the hybridization of Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. Miscanthus wangpicheonensis is found in only one locality in Uljin-gun, Gyeongsangbuk-do, Republic of Korea.

  • A new species of the genus Smenospongia (Dictyoceratida, Thorectidae), S. coreana n. sp., is described from Gageodo Island, Korea. This new species is readily distinguished from the other species of Smenospongia by the un-lobated growth forms and un-crowded primary fibres. S. aurea and S. lamellata are no distinction between primary and secondary elements, but this species is easily distinguished from them. The matrix easily derived from the fibres. This species has five sesterterpenes, three scalaranetypes and two linear furanosesterterpenes, in chemical compounds.

  • A new species, Tiphia fuscopterum Kim and Han, is described based on two specimens collected in Korea and Japan. We also report Tiphia antigenata Allen et Jaynes for the first time in Korea. Tiphia ogurai Tsuneki is synonymized with T. antigenata. Detailed descriptions and digital images of these species are provided.
