| Summary: | Oswaldella niobae Peña Cantero & Ramil, 2006 (Figs 10, 16 J, 18B, 20B) Material examined. Spanish Antarctic Expedition GEBRAP 95: Stn 5, 1 January 1997, 62°52’40’’– 62°52’58’’S, 59°59’07’’– 59°58’02’’W (Bransfield Strait), 699–922 m (MNCN 2.03/342). Description. Monosiphonic, unbranched stems, up to 68 mm high, divided into internodes. Cauline apophyses with one (Fig. 10 C) or two axillary nematophores (Fig. 10 B), each emerging through simple perisarc hole, and, usually, an extra nematophore emerging from ‘mamelon’ (Fig. 10 B). Hydrocladia unbranched (Fig. 10 A) or bifurcated. First hydrocladial internode bifurcated, with two similar prongs. Mesial inferior nematophore emerging from marked swelling at basal half of internode (Fig. 10 E); without nematotheca (Fig. 10 D–E). Hydrotheca situated on distal half of internode (Fig. 10 A, D–E). Hydrotheca low, as high as wide. Abcauline hydrothecal wall straight, angle with long axis of internode ca. 45°. Adcauline wall mostly adnate. Hydrothecal aperture ... : Published as part of Molinero, A. González & Peña Cantero, A.
