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.

Bibliographical noteFunding Information:
We would like to thank the officers and crew of the RV Dr Fridtjof Nansen for their support at sea during this and other cruises that have allowed us to explore the diversity of African jellyfish. Special words of thanks are also due to our colleagues from IMR and the region for their help at sea. We are very grateful to the EAF Nansen Programme of the FAO for providing space for us on the RV Dr Fridtjof Nansen, and for building jellyfish science into their on-going efforts in the region. Michael Brown is grateful to the National Research Foundation for bursary support and indeed, the analysis of data would not have been possible without wider support from the NRF. We would also like to thank Ross Spries for his contribution to some of the illustrations. We acknowledge the ongoing support provided by the University of the Western Cape. Delphine Thibault thanks the “Institut de Recherche pour le Développe-ment”, Aix-Marseille Université and the LMI ICEMASA for financial assistance. We would also like to thank the editor and reviewers for their contributions, which served to strengthen the quality of this paper.
