The purposes of this application, under Articles 78.4.1 and 23.9.3 of the Code, are 1) to request a review and reversal of Opinion 2404 issued by the Commission in 2017 in response to Case 3633, and 2) to conserve the specific name Exaiptasia pallida (Agassiz in Verrill, 1864) for a species of sea anemone (Cnidaria, Actiniaria) that is widely used as a model system for studies of dinoflagellate-cnidarian symbiosis and coral bleaching. Exaiptasia diaphana (Rapp, 1829) is the senior subjective synonym of E. pallida. The requirements for reversal of precedence (Art. 23.9.1) of the name E. pallida with respect to E. diaphana are not all met, specifically Art. In the interest of minimizing taxonomic confusion and maintaining nomenclatural stability, we propose to conserve the use of the junior synonym E. pallida in place of the senior synonym E. diaphana.
