Popis:	During the Spanish Antarctic expedition GEBRAP96 a survey to study the benthic fauna associated with deep volcanic structures in the Bransfield Strait was carried out. Amongst the benthic samples, a small collection of hydroids was gathered. A total of 10 species, most of them Leptothecata, was recorded; only two species of anthoathecates were present. Kirchenpaueriidae and Sertulariidae were the dominant families, and Symplectoscyphus and Oswaldella the predominant genera. Oswaldella niobae sp. nov. is described and figured. Since samples were taken at great depth, the lowest limit of the bathymetrical distribution for several species is distinctly increased. None of the samples showed signs of hydrothermal phenomena and the species of hydroids present were typical representatives of the Antarctic benthic hydroid fauna.
