Type specimen. Holotype (NIBRIV0000879329), Korea: Anheung Harbor, Geunheung-myeon, Taean-gun , Chungcheongnam-do, Mar 1986, Sim, C. J., by fishing net, deposited in NIBR.

Description. Long body sponge, spirit with several parts at the top of the sponge, size 17 × 4 × 2 cm. Surface smooth, ectoderm hard due to thick tangential arrangement of spicules. Oscules very rare, 1.2 mm in diameter. Color dirty grayish yellow. Texture very hard and compressible.

Skeleton: Thick tylostrongyles, 200-340 × 8-10 μm, thin tylostrongyles, 260-350 × 2-5 μm, and tylostyles, 150-350 × 2-10 μm. Microrhabds, 20-45 μm.

Etymology. The species name, anheung, is named after the type locality of Anheung Harbor, Chungcheongnam-do.

Remarks. This new species is similar to Suberites virgultosa in growth form, but differs in texture and spicules types. The new species has mostly tylostrongyles, as opposed to tylostylesin S. virgultosa . Texture of new species is very hard like stone because the surface skeleton is covered with a thick tangential arrangement of spicules and choanosome is slightly compressible. S. virgultosais softer than this new species.
