Eudendrium sp.2 (Fig. 3j) Material examined. ANT XXI/2: PS65/248, one colony, c. 80 mm high, with male gonophores. Remarks. This species is characterized by having a strongly polysiphonic stem, up to 80 mm high, with smooth perisarc. Only 8–9 polyps remain in the material examined. Male gonophores are mono- or bichambered, up to nine per polyp (Fig. 3j). The cnidome consists of microbasic euryteles of two size classes: the smaller [range 10.5–12.0 x 5.0–5.5 µm, mean 11.3±0.5 x 5.1±0.2 µm (n=15)], abundant on tentacles, and the larger [range 32.0– 35.5 x 16 –18.0 µm, mean 33.5±1.4 x 17.1±0.6 µm (n=16)] are scarce on the hypostome. The present material agrees, in the shape of the colony and the size of the nematocysts, with the material described as Eudendrium sp.1 by Peña Cantero (2009) and reported anew by Peña Cantero (2014a). As stated by this author, the material could be conspecific with Eudendrium cyathiferum Jäderholm, 1904, but the cnidome of Jäderholm’s species remains unknown and further ... : 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 14, DOI: 10.11646/zootaxa.4570.1.1, http://zenodo.org/record/2608527 ...
