Note When Forbes (1846: 286) defined the genus...
«..founded for Cytaeis octopunctata of Sars...». This type species designation was iterated in Forbes (1848) when he added Lizzia blondina Forbes, 1848 to this genus. The type species of Lizzia is thus Rathkea octopunctata (M. Sars, 1835) by original designation as well as by monotypy. This leads to the awkward situation that Lizzia Forbes, 1846 is actually a junior synonym of Rathkea Brandt, 1837. As the genus Lizzia is well known and it has been used consistently for the rather common species Lizzia blondina Forbes, 1848, it is in the interest of nomenclatural stability to maintain this usage. A case to the International Commission on Zoological Nomenclature must be made asking them to use their plenary power to overrule Forbes’s type species designation and select Lizzia blondina instead.

Diagnosis Rathkeidae medusa with four or eight simple, unbranched perradial oral tentacles inserting at level of mouth rim; with manubrial peduncle; eight or exceptionally 16 tentacle bulbs, each with one or more simple tentacles, usually with more tentacles on the perradial than the interradial bulbs; interradial medusa buds develop on manubrium; gonads enveloping manubrium.Hydroid tiny, nearly completely embedded in sponge tissue, with ramified stolons. Hydranths monomorphic, without pedicel, with one whorl of filiform tentacles. Medusa buds arise from from base of hydranths.
