Cladoplumaria anomala gen. nov., sp nov., a new genus and species of the family Halopterididae (Cnidaria : Hydrozoa) from the Chesterfield Islands region (Pacific Ocean)

摘要

This paper is the first result of the study of large collections of Plumularioidea (Cnidaria, Hydrozoa, Leptolida) collected in the seas surrounding New Caledonia (Pacific Ocean) by French expeditions. A new genus of the family Halopterididae is described and its relations with other representatives of this family are discussed. The gonosome in its shape approaches the type of phylactocarp also met with in Aglaopheniidae; while the gonothecae (female with nematothecae and male without nematothecae) are nearer to those of the family Halopterididae.
