Holotype, BANZARE Stn 41 , 65°48'S 53°16'E (Enderby Land), 209 m, three microslides: NMV F147450.1, one distal stem fragment, c. 18 mm long; NMV F147450.2, one distal stem fragment, c. 24 mm long; NMV F147450.3, one distal stem fragment, c. 15 mm long. Spanish Antarctic Expedition Bentart 95 .- Stn 3BC , one stem, c. 70 mm high; Stn 6A-2 , one stem, c. 190 mm high, with female gonothecae; Stn 10A , two stems, up to 90 mm high, with female gonothecae; Stn 22R , one stem, c. 30 mm high, on pebble; Stn 29A , 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 80–140 mm high, ...
