Abstract

Four new species, Semitaspongia jejuensis, Scalarispongia regularis, S. nigra and Dysidea violata are described from Jejudo, Korea. They were collected from 15 m depth by SCUBA diving and from intertidal area by hand. Semitaspongia jejuensis n. sp. is easily distinguished from other Semitaspongia species in growth form, conules, colour, skeletal structure, diameter of fibre and habitat. Scalarispongia regularis n. sp. is very close to S. scalaris (Schmidt, 1862) in skeletal structure, but S. scalaris has longer conules, larger meshes, longer distance between primary fibres, and highly developed subdermal canal system. Scalarispongia nigra n. sp. is very close to S. regularis in skeletal structure but can be easily distinguished by its black colour of external surface and growth form. Dysidea violata n. sp. is similar with D. ethria (Laubenfels, 1936) in sponge appearance, but D. etheria is clearly defined by its blue colour and thickness of fibre.
