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.

Four new species of the genus Hyattella (Dictyoceratida: Spongiidae); H. sinchangensis n. sp., H. mara n. sp., H. chuja n. sp. and H. lendenfeldi n. sp., were collected from Jeollanam-do and Jeju-do, Korea. Hyattella sinchangensis n. sp., H. mara n. sp., H. chuja n. sp. and H. grobosa Lendenfeld, 1889 are very similar to each other in some characters. However, Hyattella sinchangensis n. sp. characterized by no special dermal lamella and no tertiary fibres, and more thin secondary fibres than H. globosa. Hyattella mara n. sp. is differs in having well developed dermal lamella, slightly fasciculated primary fibres, and thick tertiary fibres. Hyattella chuja n. sp. differs in surface characters with a slightly elevated part, skeleton with abundant spongine, and very complex meshes. Hyattella lendenfeldi n. sp. is similar to H. tenella (Lendenfeld, 1889) in skeletal structure, thickness of primary and secondary fibres, but differs in growth form.

Two new species of the family Spongiidae, Spongia (Heterofibria) cora/lina n. sp. and Spongia (Heterofibria) purpurea n. sp. are described. They were collected from Gageodo Island, Jeollanam-do, Korea. Spongia (H.) coral/ina n. sp. is closest to S. (H.) cristata Cook & Bergquist (2001) from New Zealand in skeletal features, but the new species differs from S. (H.) cristata by the arrangement of fibres and growth form. Spongia (H.) purpurea n. sp. closley resembles S. (H.) cristata, but the new species differs from New Zealand specimens by the arragement and thickness of pseudo-tertiary fibres.

Five new species of the genus Hyattella (Dictyoceratida: Spongiidae); Hyattella chaguiensis n. sp., H. munseomensis n. sp., H. sumsangiensis n. sp., H. bakusi n. sp., and H. purpurea n. sp., were collected from Jeju-do, Korea. Hyattella chaguiensis n. sp. is similar to H. mara Sim and Lee, 2014 in shape, but differs in dermal membrane and primary fibres. Hyattella munseomensis n. sp. differs in cored primary fibres, having middle-size sand. Hyattella sumsangiensis n. sp. is characterized by color changes and very soft texture. Hyattella bakusi n. sp. and H. purpurea n. sp. are similar in shape, having tube-like elevated holes, but differ in skeletal structures.

Five new species of the genus Hyattella (Dictyoceratida: Spongiidae) were collected from Jejudo and Gageodo, Korea: Hy. gukheulensis n. sp., Hy. regularis n. sp., Hy. lenis n. sp., Hy. membrana n. sp., and Hy. asper n. sp. Hyattella gukheulensis n. sp. is similar to Hy. munseomensis Sim et al., 2015 in shape, but differs in skeletal structure. Hyattella regularis n. sp. is close to Hy. bakusi Sim et al., 2015 but differs in regular secondary fibres at the surface membrane. Hyattella lenis n. sp. is unique by having numerous windings at the surface. Hyattella membrana n. sp. is similar to Hy. bakusi Sim et al., 2015 in shape, but differs in surface and skeletal fibres. Hyattella asper n. sp. is close to Hy. lendenfeldi Sim and Lee, 2014 in skeletal fibres, but differs in thin secondary fibres. This new species has numerous dense cored primary fibres.

This paper describes eight new species of the genus Coscinoderma from Chuuk Island, the Federated States of Micronesia. This genus is characterized by very fine, meandering uncored secondary fibres. All the new Coscinoderma species are compared with eight other valid species from tropical regions. Coscinoderma folium n. sp. is characterized by its large thickly foliate shape, and cored primary fibres are easily found between secondary fibres in choanosome. Coscinoderma lacium n. sp. differs in having round conules and no cored primary fibres. Coscinoderma cavernosa n. sp. is distinguished from other species by its cavernous shape and long sharp conules. Coscinoderma wenoa n. sp. is characterized by long conules and primary fibres. Coscinoderma mappula n. sp. differs in having a thick sand crust in the choanosome. Coscinoderma bakusi n. sp. is characterized by having several oscules at the top of the sponge and color changed grey to dark brown in alcohol. Coscinoderma pollax n. sp. is characterized by having a small thumb shape. Coscinoderma truki n. sp. similar to C. pollax in shape but differs in cored primary fibres with many spicules.
