Seven new species in two genera, Sarcotragus and Bergquistia (Demospongiae: Dictyoceratida: Irciniidae), are described from Jeju Island, Korea. The separation of the two genera was made on basis of morphological evidence in skeletal structure, especially fasciculation of primary fibres and filament thickness. Two new species in the genus Sarcotragus and five new species in the genus Bergquistia are compared with other reported species.

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.

Sponges of the family Irciniidae are poorly known in Korean waters. This paper describes a new species of new genus, Bergquistia coreana n. sp. in the family Irciniidae (Demospongiae: Dictyoceratida) from Jejudo Island, Korea from 1998 to 1999. Bergquistra n. gen. is characterized by extremely simple fasciculated and uncored primary fibres. However, in the choano-somal region, primary fibres are made of wider clear web. Secondary fibres form a very thin regular uncored network. The sponge surface has thick and regular conules. The colour is beige throughout the sponge, and the texture is slightly hard and compressible. Thickness of filament is variable.
