Diagnosis. Capitata with a planula stage in the life cycle. Remarks. Planulate Capitata were retained in Capitata Kühn, 1913 , sensu stricto , by Cartwright et al . (2008) . To avoid confusion, this name should be changed. Molecular studies by Nawrocki et al . (2010) suggest the presence of two clades within the group, namely the Corynida (including Corynidae Johnston, 1836 and Cladonematidae Gegenbaur, 1857 ) and Zancleida (including Hydrocorynidae Rees, 1957a , Pennariidae McCrady, 1859 , Moerisiidae Poche, 1914 , Sphaerocorynidae Prévot, 1959 , Porpitidae Goldfuss, 1818 , Zancleidae Russell, 1953 , Asyncorynidae Kramp, 1949 , Milleporidae Fleming, 1828 , Cladocorynidae Allman, 1872 , and Solanderiidae Marshall, 1892 ).
