Calvadosia is a genus of stalked jellyfish in the order Stauromedusae.
It is the only genus in the monotypic family Kishinouyeidae.
The family name is a tribute to Japanese cnidariologist Kamakichi Kishinouye.
Mayer used the synonym Kishinouyea as a replacement name of Schizodiscus, for homonymy, as the name was already used to describe a lichen genus.
Kishinouyea was also used by Yoshio Ôuchi to describe a praying mantis genus that he quickly renamed Kishinouyeum in 1938, and that could be a junior synonym for Phyllothelys.
