ABSTRACT: The family Tealidae Hertwig, 1882 is reinstated to include the genera Urticina and Cribrinopsis, formerly assigned to Actiniidae, and Urtibrina gen.n. Members of this family have mesenteries with a strong tendency toward decamerous arrangement. Sequences of 16S rRNA of all included species have long insertion termed here as “Tealidae-insertion”, which is unique to the family. The new genus Urtibrina gen.n. is created for Urticina clandestina and a new species Urtibrina rimicola sp.n., both recorded from British Columbia, Canada and Washington State, USA. The genus Urtibrina gen.n. has all the features of Urticina but differs from it in possessing gonads on the mesenteries of all cycles and is supported by molecular analysis.
KEY WORDS: Sea anemones, synapomorphy, North East Pacific, family Tealidae, Cnidaria, Anthozoa, Actiniaria, Urtibrina gen.n., Urtibrina rimicola sp.n.
