Genus Aiptasiogeton Schmidt, 1972

Diagnosis (after Schmidt 1972). Aiptasiidae with wide, regularly shaped pedal disc. Column elongate, smooth (in some species with accumulations of nematocysts), with cinclides in mid-column. Column not distinctly divisible into scapus and capitulum. Mesogleal marginal sphincter weak. Strong longitudinal ectodermal muscles in distal column. Tentacles long, simple, to 170, always smooth, without projections. More mesenteries distally than proximally. Eight perfect mesenteries proximally. All cycles of mesenteries fertile. Retractor muscles restricted. Acontia well developed. Zooxanthellae absent. Asexual reproduction by pedal laceration. Cnidom: spirocysts, basitrichs, and microbasic b -mastigophores and p -amastigophores.

Type species. Paractis comata Andres, 1881 by monotypy.

Included species. Aiptasiogeton eruptaurantia ( Field, 1949) ; A. hyalinus ( Delle Chiaje, 1822) , Aiptasiogeton parva ( Carlgren, 1938) .

Taxonomic remarks. We modified the number of tentacles (up to 170) and added the presence of accumulations of nematocysts in the column in some species in the diagnosis of the genus to reflect the description of Aiptasiogeton eruptaurantia and A. parva (former Aiptasia parva , see below), respectively.
