Two new marine species of the family Halichondriidae, Ciocalypta sasuensis n. sp. and Epipolasis maraensis n. sp., are collected from Chujado Island and Jejudo Island, Korea during 2000-2005. Ciocalypta sasuensis n. sp. is closely related to C. penicillus(Bowerbank, 1864) in the type of shape and ectosomal skeleton. However, C. sasuensis n. sp. is larger than Ciocalypta penicillus. Epipolasis maraensis n. sp. is similar to E. suluensis(Wilson, 1925) in the type of skeleton, but is different in size of spicule and growth form. Its oxeas and raphide are smaller than E. suluensis's. The growth form of this new species is semispherical and massive, but E. suluensis is lamellated.
