Moreover, Ramil (1988), in his study of the hydroids of Galicia (NW Spain), described this species as Clytia sp., apart from C. hemisphaerica, based on the same features highlighted by Calder (2012).

The material studied here also resembles C. joycei Calder, 2019 in the hydrothecal shape; however, C. joycei is a shallow-water species, growing on the seagrass Thalassia testudinum K.D.
