N.P. Sanamyan & K.E. Sanamyan

Abstract. Tetracoelactis ioran gen. et sp. nov. is described from abyssal depths of the NW Pacific and assigned to the family Exocoelactinidae. The genus is unique in having of only four meristematic zones, the lowest number among all species of Actiniaria.
Key words: sea anemones, mesenterial arrangement, abyssal, NW Pacific, Anthozoa, Actiniaria, Exocoelactinidae, Tetracoelactis, new genus, new species
