In this paper, two new species of the genus Rosalinda found growing on bivalves from West African cold-water coral mounds are described. Rosalinda nowaldi sp. nov. was found on Acesta angolensis (Adam & Knudsen, 1955) off northern Angola, and Rosalinda lundalvi sp. nov. on Acesta excavata (Fabricius, 1779) off Mauritania. Both new species have a similar cnidome, but they can be easily differentiated by the structure of their hydrorhizae and number of tentacles of the hydranths. The differences between the new species and all other species included in the genus Rosalinda on the basis of their morphology, habitat and geographical distribution were also established.

在本文中，描述了在西非冷水珊瑚丘的双壳类动物上发现的罗莎琳达属的两个新物种。罗莎琳达·诺瓦迪（Rosalinda nowaldi sp。）十一月 在安哥拉北部附近的Acesta angolensis（Adam＆Knudsen，1955）和Rosalinda lundalvi sp。上发现。十一月 在毛里塔尼亚附近的Acesta excavata（Fabricius，1779）上。两种新物种都有一个相似的刺突，但是它们的水生根茎结构和hydr的触角数量很容易区分它们。还确定了新物种与罗莎琳达属中所有其他物种之间在形态，生境和地理分布上的差异。
