  • Sponges of the family Spongiidae are poorly known in Korean waters. This paper describes Hippospongia bergquistia n. sp. of the family Spongiidae (Demospongiae: Dictyoceratida) collected from Moselpo, Jejudo Island, Korea in 2007. This new species has a cavernous construction, rare pseudo-tertiary fibre, and rare primary fibres.

  • 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.

  • We surveyed the freshwater invertebrates of Jindo Island twice on July and September 2016, as part of a joint faunal survey conducted to commemorate the 30th anniversary of the Korean Society of Systematic Zoology. Aquatic insects were not included in this study. We found 38 freshwater species from seven phyla: Porifera, Platyhelminthes, Nematomorpha, Mollusca, Annelida, Arthropoda, and Bryozoa. Twenty-one of the 38 species (55.3%) represented the first record of their respective species on Jindo Island. Among these species, a freshwater shrimp-parasitic isopod, Tachaea n. sp., was identified as a new species.

  • This paper describes six new species of sponges in the genus Agelas from Kosrae Island, The Federated States of Micronesia. Most Agelasid sponges are known from only tropical regions. All the new Agelas species; A. fragum n. sp., A. kosrae n. sp., A. purpurea n. sp., A. bakusi n. sp., A. vansoesti n. sp. and A. incrustans n. sp. are compared with other valid species that were studied. Six new species differ from the other species by morphology, growth form, skeletal fibres, habitats and spicule size. Agelas fragum n. sp. is characterized by its tuberculate surface and primary fibres with brush-like spicules. Agelas kosrae n. sp. is differs in skeletal structure and have tertiary fibres. Agelas purpurea n. sp. is characterized by primary, secondary and tertiary fibres are all cored with spicules. Agelas bakusi n. sp. is similar to Agelas clathrodes in shape, but differs in the primary fibres. Agelas vansoesti n. sp. is characterized by having acanthostrongyles. Agelas incrustans n. sp. is distinguished by its encrusting and not cavernous interior.

  • The development of suitable genetic markers would be useful for defining species and delineating the species boundaries of morphologically indistinguishable sponges. In this study, genetic variation in the sequences of nuclear rDNA and the mitochondrial cytochrome c oxidase subunit 1 and 3 (CO1 and CO3) regions were compared in morphologically indistinguishable Korean Halichondriidae sponges in order to determine the most suitable species-specific molecular marker region. The maximal congeneric nucleotide divergences of Halichondriidae sponges in CO1 and CO3 are similar to those found among anthozoan cnidarians, but they are 2- to 8-fold lower than those found among genera of other triploblastic metazoans. Ribosomal internal transcribed spacer regions (ITS: ITS1 + ITS2) showed higher congeneric variation (17.28% in ITS1 and 10.29% in ITS2) than those of CO1 and CO3. Use of the guidelines for species thresholds suggested in the recent literature indicates that the mtDNA regions are not appropriate for use as species-specific DNA markers for the Halichondriidae sponges, whereas the rDNA ITS regions are suitable because ITS exhibits a low level of intraspecific variation and a relatively high level of interspecific variation. In addition, to test the reliability of the ITS regions for identifying Halichondriidae sponges by PCR, a species-specific multiplex PCR primer set was developed.
