| Summary: | Oswaldella grandis Peña Cantero, Svoboda & Vervoort, 1997 (Figs 7, 16 G, 17G, 19G) Material examined. Spanish Antarctic Expedition Antártida 8611: Stn NA 172, 61°01'S – 60°58'S, 55°34'– 55°56'W (Elephant Island, South Shetland Islands) (Department of Zoology, University of Valencia, ANT NA 172). Description. Polysiphonic, unbranched stems, up to 500 mm high, usually divided into internodes. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with four to five nematophores, two to three axillary ones, each emerging through simple hole in perisarc, and other two nematophores, each emerging through ‘mamelon’ (Fig. 7 B–C). Hydrocladia much branched (Fig. 7 A), with up to third-order hydrocladia. First hydrocladial internode bifurcated (Fig. 7 A), with two similar prongs. Mesial-inferior nematophore typically with much reduced nematotheca, though not existent in present material (Fig. 7 D–F). Unforked hydrocladial internodes without infrathecal swelling. Hydrotheca placed on distal half of ... : Published as part of Molinero, A. González & Peña Cantero, A.
