Size up to 13 × 9 × 3.5 cm. Surface smooth with shallow cavities covered with thick membrane. Oscules with large opening, 0.5-1 cm in diameter at sponge surface. Color in life, purple at surface and yellowish beige inside. Texture very firm and compressible.</p> <p>Skeleton: Primary fibres, 30-50 μm in diameter, usually rare at surface and choanosome. Secondary fibres, 20-35- 40 μm in diameter, arranged irregularly. Thin secondary fibres, 10 μm in diameter on surface membrane.</p> <p>Etymology.

Kim, SCUBA diving, depth 20 m, deposited in NIBR.</p> <p>LSID urn:lsid:zoobank.org:act: 94DEE649-E4AB-4FFD- A8A2-0F9699D18EB7</p> <p>Description. Thickly encrusting sponge. Size up to 13 × 11 × 5.5 cm. Surface rough with small round swelling covered with thick membrane. Oscules rare, 1 cm in diameter, open at tip of protruding structure. Color in life, yellowish purple. Texture firm and compressible.</p> <p>Skeleton: Primary fibres, connected with long conules at surface, 40-70 μm in diameter, abundant throughout sponge body. Secondary fibres, regular mesh, 40-50 μm in diameter. Thin and thick regular polygonal network at surface membrane, 5-10 μm in diameter (Fig. 2H).</p> <p>Etymology. The species name, regularis, is named after the regular shape of secondary fibres at the sponge surface membrane.</p> <p>Remarks. This new species is similar to Hy. bakusi Sim et al., 2015 in shape, but differs in regular secondary fibres mesh at the surface.</p> <p>3. Hyattella lenis n. sp. (Fig. 3) DZōḑḍďẖųệợ</p> <p>Type specimen. Holotype (NIBRIV0000895362), Korea: Geomeunyeo, Gageodo Island, Heuksan-myeon, Shinan-gun, Jeollanam-do, 21 September 2008, collected by H. S. Kim, SCUBA diving, depth 20 m, deposited in NIBR.</p> <p>LSID urn:lsid:zoobank.org:act: C40CCAD5-45F9-4A75- B471-38B1922F93B9</p> <p>Description. Thickly encrusting sponge. Size up to 11 × 10 × 5.5 cm. Surface smooth with numerous deep furrows and short conules, covered with thick collagenous membrane. Oscules, 0.3-1 cm in diameter, open at sponge surface. Color in life, purplish ivory. Texture firm and compressible and lacunose.</p> <p>Skeleton: Primary fibres rarely cored with detritus, 40-50 μm in diameter spread throughout the sponge body (Fig. 3E, G). Thick and thin secondary fibres, 15-30 μm in diameter arranged irregularly with large mesh at surface. Thick secondary fibres, 45-50 μm in diameter at choanosome.</p> <p>Etymology. The species name, lenis, is named after the shape of the smooth surface.</p> <p>Remarks. The shape of the surface in this new species is very unique with numerous deep furrows at the smooth surface. Primary fibres which are rarely cored with sands are abundant throughout the sponge body.</p> <p>4. Hyattella membrana n. sp. (Fig. 4) ḡḍďẖųệợ</p> <p>Type specimen. Holotype (NIBRIV0000895368), Korea: Chujado, Chuja-myeon, Jeju-si, Jeju-do, 27 August 2002, collected by H. S. Kim, SCUBA diving, depth 13 m, deposited in NIBR.</p> <p>LSID urn:lsid:zoobank.org:act: 7BB77BA2-53A6-42E0- 8983-EF1108CF1C41</p> <p>Description. Thickly encrusting sponge. Size up to 14× 9.5 × 2.3 cm. Surface smooth with shallow elevated tubes, covered with thick collagenous membrane and numerous sharp conules. Large and small oscules, 2-4 mm in diameter, open at tip of sallow tubes. Color in life, purple and ivory. Texture firm and compressible.</p> <p>Skeleton: Primary fibres cored with sands, 50-75 μm in diameter at surface conules distributed throughout sponge body. Secondary fibres loose, thick and thin, 20-40 μm in diameter with no regular mesh.</p> <p>Etymology. The species name, membrana, is named after a surface with heavy collagenous membrane.</p> <p>Remarks. This new species is similar to Hyattella bakusi Sim et al., 2015 in shape, but differs by having a heavy collagenous membrane at the surface (Fig. 4C).</p> <p>5. Hyattella asper n. sp. (Figs. 5, 6) Hṻḍďẖųệợ</p> <p>Type specimen. Holotype (NIBRIV0000895369), Korea: Dueokyeo, Gageodo Island, Heuksan-myeon, Shinan-gun, Jeollanam-do, 11 Jun 1999, collected by SCUBA diving, depth 27 m, deposited in NIBR.</p> <p>LSID urn:lsid:zoobank.org:act: 75D69D2D-168F-4965- BBF0-D50BB883E0B8</p> <p>Description. Thickly encrusting, looks like bryozoan animal. Size up to 22 × 4 × 8 cm. Surface rough with sharp long conules. Color in life, ivory. Texture soft and compressible.</p> <p>Skeleton: Numerous dense primary fibres, straight long lines cored with sands, 60-75 μm in diameter, occur throughout sponge body. Secondary fibres, 30-50 μm in diameter, arranged irregularly with loose mesh. Some part of surface has hair-like thin secondary fibres, 5-10 μm in diameter. These hair-like fibres which separated from primary fibres, are not easy to locate (Fig. 5E, F, H).</p> <p>Etymology. The species name, asper, is named after the shape of rough surface of sponge.</p> <p>Remarks. This new species is similar to Hyattella lendenfeldi Sim and Lee, 2014 in skeletal fibres, but differs in thin secondary fibres. Thin secondary fibres are not easy to locate, because they separated from skeletal fibres (Fig. 5E). Secondary fibres are loosely arranged.</p> </div>	https://treatment.plazi.org/id/0423411FFFF95A17E41FF9D9FD9FFBC9	Public Domain	No known copyright restrictions apply.
