Summary:Halecium banzare Watson, 2008 (Fig. 3 A–D) Halecium banzare Watson, 2008: 167 –168, fig. 3 A–F. Halecium pallens—Broch, 1948: 4, 7– 8, fig. 1; Peña Cantero, 2004: 769; 2006: 935, fig. 3 B; 2008: 455, fig. 1 h, i; 2010: 766, fig. 4; 2013: 128, fig. 3 f; Peña Cantero & Vervoort, 2009: 85, fig. 1g, h. Halecium pallens — Stepanjants, 1979: 105, pl. 20 fig. 2 (in part). ? Halecium pallens — Galea & Schories, 2012 a: 36, pl. 3 A, B, fig. 3 G–M. Material examined. Holotype, BANZARE Stn 41, 65° 48 'S 53 ° 16 'E (Enderby Land), 209 m, three microslides: NMV F 147450.1, one distal stem fragment, c. 18 mm long; NMV F 147450.2, one distal stem fragment, c. 24 mm long; NMV F 147450.3, one distal stem fragment, c. 15 mm long. Spanish Antarctic Expedition Bentart 95.- Stn 3 BC, one stem, c. 70 mm high; Stn 6 A- 2, one stem, c. 190 mm high, with female gonothecae; Stn 10 A, two stems, up to 90 mm high, with female gonothecae; Stn 22 R, one stem, c. 30 mm high, on pebble; Stn 29 A, one stem, c. 70 mm high. Spanish Antarctic Expedition Bentart 2006.- Stn Low 46, a large, strongly polysiphonic stem, c. 135 mm high, basibiont of Filellum sp. Diagnosis. Polysiphonic stems, up to 190 mm high. Branching regular, stem giving rise alternately every third hydrotheca to paired branches forming two distinct, longitudinal series. Branches originating from hydrophore of primary hydrotheca. Hydrothecae alternately arranged in one plane. Hydrotheca at the end of long, free hydrophore close to internode and with thick perisarc development; sometimes with distinct pseudodiaphragm. Hydrothecal diameter barely increasing distally; rim very slightly everted. A single, if any, secondary hydrotheca. Male gonoteca laterally flattened, maximum width by distal third. Female gonotheca Pinna bivalve-shaped, abcauline and adcauline walls of similar length. Aperture extending the entire diameter from the widest part upwards. Cnidome consisting of microbasic mastigophores? and microbasic euryteles? Description (type material). “Colonies originally ...
