ABSTRACT

In the present paper, three algal species are recorded for the first time from Morocco: the two red algae Antithamnion villosum and Antithamnionella ternifolia and the green alga Lychaete rhodolithicola. Furthermore, two other red algae species are recorded for the first time from the Moroccan Atlantic coast and this part of the eastern Atlantic Ocean: Antithamnion amphigeneum and Antithamnionella boergesenii. Descriptions of these newly reported species are provided accompanied by photographs for each species. In addition, new observations and taxonomic remarks for some species are also provided. The green alga Lychaete rhodolithicola has a limited distribution in the North-eastern Atlantic Ocean of Europe, and the report of this species from Morocco extends the distribution of this species, because it is the first record of this species in Africa and outside Europe. This is one of the rare documentations with description and illustrations of L. rhodolithicola. The foliose species Grateloupia turuturu is studied in detail; it has been widely misidentified as G. doryphora. An examination of all specimens going under the name G. doryphora in the Moroccan herbaria has determined these specimens to be Grateloupia turuturu. An identification key for all Moroccan species of Antithamnion, Antithamnionella and Lychaete is presented.

摘要

在本文中，首次在摩洛哥记录了三种藻类：两种红藻Antithamnion villosum和Antithamnionella ternifolia以及绿藻Lychaete rhodolithicola。此外，在摩洛哥大西洋海岸和东大西洋这一部分首次记录到另外两种红藻：Antithamnion amphigeneum和Antithamnionella boergesenii。对这些新报告物种的描述附有每个物种的照片。此外，还提供了一些物种的新观察结果和分类学注释。绿藻Lychaete rhodolithicola在欧洲东北大西洋的分布有限，来自摩洛哥的该物种的报告扩大了该物种的分布，因为这是该物种在非洲和欧洲以外的首次记录。这是带有L描述和插图的罕见文档之一。红石霉属。对叶类植物Grateloupia turuturu进行了详细研究；它被广泛误认为是G。槐花。对摩洛哥植物标本馆中所有名为G. doryphora的标本进行检查后，确定这些标本是Grateloupia turuturu。所有摩洛哥物种的识别码介绍了Antithamnion、Antithamnionella和Lychaete 。
