Description
Summary:Oswaldella shetlandica Stepanjants, 1979 (Figs 12, 16 L, 18D, 20E) Material examined. Spanish Antarctic Expedition Bentart 2006: Stn Low 45, Hespérides, February 2006, 63.43171°S, 62.2116°W (Low Island, Antarctic Peninsula), 86 m (Department of Zoology, University of Valencia, BENTART 2006—LOW 45). Description. Polysiphonic, unbranched stems, up to 170 mm high, divided into internodes. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with four nematophores: two axillary ones, each emerging through simple hole in perisarc, and two other nematophores, each emerging through a strongly developed ‘mamelon’ (Fig. 12 B). Hydrocladia much branched (Fig. 12 A), with up to fourth-order hydrocladia. First hydrocladial internode bifurcated, with two similar prongs (Fig. 12 A). End of distal internodes peak-shaped (Fig. 12 A, E). Mesial inferior nematophore emerging from very strongly marked swelling at proximal third of internode (Fig. 12 C–E); without nematotheca (Fig. 12 C–E). Hydrotheca elongate, ... : Published as part of Molinero, A. González & Peña Cantero, A.
