Abstract

A new species of the cosmopolitan jellyfish genus Aurelia is described from the coastal waters of Mozambique using a combination of morphological, meristic and genetic information (COI and 18S). The species can be separated from congeners that have been recently described by a combination of bell shape, number of canal origins and anastomoses, and the shape of the manubrium and oral arms. Three types of nematocysts are present in the tissues of both the bell margin and oral arms, and this description of the cnidome will allow for future comparison. Pairwise genetic comparisons showed a mean COI divergence of 4.8% within the group, and a mean divergence ranging between 15% and 22% with all other species of Aurelia.

摘要

描述了一种来自莫桑比克沿海水域的世界性水母属 Aurelia 的新物种，使用了形态学、数量和遗传信息（COI 和 18S）的组合。该物种可以通过钟形、管道起源和吻合的数量以及柄和口臂的形状与最近描述的近缘种相区分。两种类型的刺胞在钟形边缘和口臂组织中均有存在，对刺丝囊的这种描述将允许未来进行比较。成对的 COI 遗传比较显示，该组内的平均分歧为 4.8%，与 Aurelia 的所有其他物种的平均分歧在 15%至 22%之间。
