Seven new species of two genera Scalarispongia and Smenospongia (Demospongiae: Dictyoceratida: Thorectidae) from Korea Author Kim, Young A Natural History Museum, Hannam University, Daejeon 34430, Republic of Korea Author Sim, Kyung Jin Lee and Chung Ja text Journal of Species Research 2020 9 2 147 161 journal article 10.12651/JSR.2020.9.2.147 2713-8615 13140301 6. Smenospongia aspera n. sp. ( Figs. 8 , 9 ) Ąṻċḑƚḓậ (ljÿ) Type specimen. Holotype (NIBRIV0000862773), Korea : Jakeunganyeo , Gageodo-ri , Heuksan-myeon , Sinan-gun , Jeollanam-do , 26 Jun 2000 , collected by H. J. Kim and K. J. Lee , by SCUBA , depth 15 m , rocky substrate, deposit- ed at NIBR . Description. Round mass sponge, size up to 7 × 7 × 5.5 cm . Surface rough with thick conules which made groove and covered with thick membrane. Skeletal fibres easily separated from ectodermal matrix because of very simple secondary fibres structure. Several oscules, 1-4 mm in diameter, open on top of sponge. Color in life gray turns to dark brown. Texture firm and compressible. Skeleton: Primary fibres with three-dimensional arrangement, 100-250 μm in diameter. Secondary fibres, 40-100 μm in diameter, long bridge type ( Fig. 8D, F ) and partly web type between primary fibres ( Fig. 8C, G, H ). Etymology. This species name, aspera , is named after its rough surface. Remarks. This new species is similar to Smenospongia coreana Lee and Sim, 2005 ( Fig. 11 ) in sponge shape but differs in surface and skeletal structure. Secondary fibres of Sm. coreana has rather complex mesh throughout the sponge but this new species has secondary mesh at near surface conules.
