| Forty-six species of the superfamily Plumularioidea (Hydrozoa, Cnidaria) and some material identified to the generic level, collected by the CANCAP and Mauritania-II expeditions of the Rijkmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) in the period 1976-1988, are described, as well as two other species that were used in the present study. In addition to the descriptions, synonymy, variability and geographical distribution are discussed; autoecological data and measurements are also presented. The new species described here are: Aglaophenia svobodai spec. nov., Streptocaulus caboverdensis spec. nov., S. chonae spec. nov., Antennella confusa spec. nov. and Nemertesia anonyma spec. nov. All species are figured. The general... |

| A cladistic study was carried out on known species of the characteristically Antarctic genus Oswaldella, adopting as outgroups some other genera included in the family Kirchenpaueriidae. The analysis resulted in a cladogram with low CI in which no relationship between genera can be depicted. However, the hypothesis of monophyly of the genus Oswaldella is corroborated, being supported in our cladogram by five synapomorphies (although all are homoplastic with other taxa or reversed within the species of the genus). The basal relationships of the genus are uncertain, but three species groups are distinguishable within Oswaldella: 1) the O. incognita group, 2) the O. antarctica group, and 3) a clade formed by (O. garciacarrascosai, O. elongata ( O. blanconae... |
