| 摘要: |
| 利用生物压片技术，通过形态学和解剖学方法，对采自我国沿岸海洋的仙菜科红藻（Ceramiaceae，Rhodophyta）进行了分类学研究，发现了我国仙菜科新记录属——盖氏藻属（新拟名）Gayliella T.O.Cho，L.McIvor et S.M.Boo。该属目前在我国共有5个种，即短毛盖氏藻（新拟名）Gayliella fimbriatum（Setchell et N.L.Gardner）.T.O.Cho et S.M.Boo、优美盖氏藻（新拟名）Gayliella flaccidum（Kützing）T.O.Cho et L.McIvor、泰式盖氏藻（新拟名）Gayliella taylorii（E.Y.Dawson）T.O.Cho et S.M.Boo、马沙盖氏藻（新拟名）Gayliella mazoyerae T.O.Cho，Fredericq et Hommersand和横轴盖氏藻（新拟名）Gayliella transversalis（Collins et Hervey）T.O.Cho et Fredericq，其中前3个种为由仙菜属Ceramium归并的物种，后2个为我国的新记录种。本文对此2个新记录种进行了详细的形态学描述，并讨论了它们与中国已报道的横列仙菜Ceramium gracillimum间的关系。该研究结果丰富了我国海洋仙菜科的物种多样性。 |

| Abstract: |
| A new record genus, Gayliella, was found in the taxonomic study on red algae of Family Ceramiaceae collected from the coast of Shantou, Guangdong, South China by Bio-film technology and method of morphological anatomy. There are 5 species in this genus from Chinese coasts, namely Gayliella fimbriatum (Setchell et N. L. Gardner). T. O. Cho et S. M. Boo, G. flaccidum (Kützing) T. O. Cho et L. McIvor, G. taylorii (E. Y. Dawson) T. O. Cho et S. M. Boo, G. mazoyerae T. O. Cho, Fredericq et Hommersand, and G. transversalis (Collins et Hervey) T. O. Cho et Fredericq. The first three species are transferred from genus Ceramium, and the last two are new Chinese records. The two new records are described morphologically in details and discussed withtheir closely related species including Ceramium gracillimum previously reported in the Chinese coasts. The results enrich the species diversity of marine Family Ceramiaceae in Chinese coasts. |
