Case 3805 – Calliactis Verrill, 1869 (Cnidaria, Anthozoa, Hexacorallia, Actiniaria): proposed precedence over Adamsia Forbes, 1840

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the name Calliactis Verrill, 1869 for a genus of sea anemones (Cnidaria, Actiniaria) that has been widely studied in the context of crustacean-cnidarian symbiosis. This name is threatened by a senior subjective synonym, Adamsia Forbes, 1840. In the interest of nomenclatural stability, we ask the ICZN Commission to use its plenary power to reverse the precedence of Calliactis Verrill, 1869 and Adamsia Forbes, 1840 whenever the two names are considered synonyms.
