| Summary: | Eudendrium antarcticum Stechow, 1921 (Fig. 3g) Material examined. ANT XV/3: 48-31, one colony, c. 15 mm high, on O. terranovae and Tubularia sp.1; 48-77, one colony, c. 15 mm high, with female gonophores; 48-197, one colony, c. 50 mm high; 48-276, one colony, 20 mm high, on B. subrufa; ANT XVII/3: 111-19, one colony, c. 4 mm high, on H. interpolatum; ANT XXI/2: PS65/ 292, one colony, c. 7 mm high. Remarks. Non-reproductive material was attributed based on the cnidome, consisting of microbasic euryteles of only one size category [range 7.0–8.0 x 1.5–2.5 µm, mean 7.8±0.3 x 2.3±0.3 µm (n=23)], in agreement with previous material examined by Peña Cantero & Gili (2006) and Peña Cantero & Vervoort (2009). In the material examined here, unlike previous reports of the species (e.g. Puce et al. 2002), the female gonophores originated from partially atrophied hydranths with a reduced number of tentacles (Fig. 3g), probably due to the complete maturation of the gonozooid, as known to occur in other species of ... : Published as part of Soto, Joan J. & Peña, Álvaro L., 2019, Benthic hydroids (Cnidaria, Hydrozoa) from the Weddell Sea (Antarctica), pp. 1-78 in Zootaxa 4570 (1) on page 12, DOI: 10.11646/zootaxa.4570.1.1, http://zenodo.org/record/2608527 ... |
