| Summary: | Halecium interpolatum Ritchie, 1907 (Fig. 15 F) Halecium ovatum Totton, 1930: 143 –144, fig. 3; Peña Cantero et al., 2013: 745–747, fig. 6b. Halecium interpolatum — Peña Cantero, 2014b: 261 –263, figs 5G–J, 8A–B (synonymy). Material examined. Stn 7, a few slightly polysiphonic stems up to 8 mm high on Antarctoscyphus grandis (NIWA 117594); Stn 67, two stems up to 3 mm high on Staurotheca nonscripta (MNCN 2.03/648); Stn 107, slightly polysiphonic stem ca. 19 mm high (NIWA 117595). Measurements (in µm). Hydrothecae: diameter at aperture 150–245, diameter at diaphragm 100–145, height 45–65. Cnidome: microbasic euryteles (10.5–12.0 x 6.0–6.5) and microbasic mastigophores (6.5–7.0 x 2.0). Remarks. Species easily identifiable by its typical scorpioid stems, with internodes arranged in zigzag and paired branches originating from hydrophore of primary hydrotheca, one on each side. Additionally, internodes characteristically have a long and straight basal part (Fig. 15 F). Hydrothecae are high, flared, with a ... : Published as part of ÁLVARO L.
