| All genera and species of the hydrozoan family Halopterididae are reviewed. Where material was available, species are described and figured and the extent of morphological variation is assessed as far as possible. The re-examined material includes samples from the Challenger, Siboga, and Galathea expeditions. Numerous types were re-examined and taxonomic revisions made where necessary. For several nominal species lectotypes are designated. Two new species are described: Antennella kiwiana from New Zealand and Halopteris platygonotheca, a wide spread species from the Indo-Pacific Ocean. Halopteris buskii var. peculiaris (Billard, 1913) is raised to species level as Halopteris peculiaris. Several species are sunk into synonymy: Plumularia balei Billard, 1911... |
