| 摘 要： | 本研究发现了采集于南海北部湾和琼州海峡的一个海绵新记录种,白银拟族海绵。该种是丛生薄管状,具有很多分叉的树枝状结构,同一根独立的管粗细均匀。标本在酒精中的颜色为淡褐色,出水口处颜色稍浅。海绵坚硬且脆度大,一层大二辐骨针在海绵表面构成致密的骨架结构,有少量骨针的辐会伸出表面。骨针分为三类:大二辐骨针和小二辐骨针;成对辐与无对生辐长度及形态差异非常明显的四种羽状三辐骨针;基辐与顶辐差异不明显且均与三辐骨针的辐相似的四辐骨针,这三种骨针按照固定的方式组合在一起构成骨架结构。水沟系是双沟型。领细胞室没有关节结构。

| Abstract: | A new record of Uteopsis argentea (Poléjaeff, 1883) collected in the Beibu Gulf and Qiongzhou Strait of the South China Sea is described. This sponge has arborescent structure made of many tubes, and every tube has uniform thickness. The sponge is light brown in alcohol, and the oscula is slightly lighter. The texture is hard and brittle; large diactines cover the surface formed a dense and rigid structure; and a several small diactines protrude out of the surface. The sponge has three types of spiculation:(1) diactines including large and small diactines; (2) triactines:sagittal, in terms of the length of paired actines and unpaired actines, triactines can be divided into four types; (3) tetractines:sagittal, apical actines, and basal actines are similar to the actines of triactines. All these spiculation assembled and organized orderly and regularly for forming the skeleton. The aquiferous system is syconoid. In addition, the choanoskeleton is inarticulated. |
