  • 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.

  • 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.
