  • 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.

  • 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 total of 121 species of lichens belonging to the genus Arthothelium have been described to date, most of which have been found in tropical regions. Here, we describe the discovery of a novel Arthothelium species for the first time in South Korea. Until now, Arthothelium ruanum was the only Arthothelium species reported in South Korea. Among the 113 specimens collected in this study, we identified A. ruanum and a putative new species, Arthothelium punctatum (J. S. Park & J.-S. Hur, sp. nov.). The diagnostic characters of A. punctatum are as follows: apothecia punctate, shortly elongate to branched, small, 0.1-0.2 mm wide, hypothecium hyaline to pale brown and obovate to broadly ellipsoid, muriform ascospores, $29.5-44.6{\times}12.2-18.2{\mu}m$. The new species was found in Mt. Seokbyeong at an altitude of 790 m on smooth bark. Upon phylogenic analysis, the putative new species, A. punctatum, was separated from other Arthothelium species although the specimens analyzed were clustered with Arthoniaceae in phylogenetic trees based on both the mitochondrial small subunit (mtSSU) sequence and combined mtSSU and nuclear ribosomal large subunit sequences. Our data clearly indicate that this species is a new species belonging to the family Arthoniaceae. To elucidate the taxonomic characteristics of the new species, we provide morphological descriptions and a distribution map.

  • 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.

  • A new species, Tritoma gangwonensis sp. nov., is described. Also three species - Rhodotritoma fitlva (Reitter, 1879), Triplax discicollis Lewis, 1887 and Triplax signaticollis Reitter, 1879 - are reported for the first time in Korea. A description and redescriptions for each species, photographs of adults and illustrations of diagnostic characters are provided.
