Última Review of the family Halopterididae (Hydrozoa, Cnidaria) Naturalis Schuchert, P.. 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...

Ano: 1997 URL: http://www.repository.naturalis.nl/record/317731 How many hydrozoan species are there? Naturalis Schuchert, P.. A list of all living hydrozoan species was compiled and analysed. The number of supposedly valid species was found to be around 3200. Considerable uncertainties exist due to the possibly high number of invalid nominal species. The total number of existing hydrozoan species cannot be estimated because the accumulation curve for new species shows no sign of convergence. Only in the Thecata, Narcomedusae and Trachymedusae is an estimate of the maximal number feasible. However, application of new methods, notably a molecular systematic approach, could drastically alter these predictions.
