Symplectoscyphus weddelli Peña Cantero, Svoboda & Vervoort, 2002 (Figs 12 I, 13B) Symplectoscyphus weddelli Peña Cantero et al. 2002: 1560 –1562, fig. 16; Peña Cantero, 2010a: 41 –42. Material examined. Stn 53, fragment 10 mm long (MNCN 2.03/643); Stn 134, several incipient stems up to 13 mm high on tubes of benthic organism (NIWA 117588). Description. Monosiphonic stems, up to 13 mm high. Typically unbranched (only three stems with primary branch). Stems divided into somewhat straight internodes. Hydrothecae alternately arranged in approximately one plane. Hydrotheca (Figs 12 I, 13B) roughly cylindrical, gradually curved abcaudally. Adcauline wall convex; without inflexion point where adcauline wall becomes free. Abcauline wall roughly straight basally and slightly concave at distal half. Cusp of hydrothecal aperture sharp and separated by deep embayments. Measurements (in µm). Hydrothecae: length abcauline wall 350–400, length free part of adcauline wall 280–290, length adnate part of adcauline wall ... : Published as part of ÁLVARO L.
