| Summary: | Hydrodendron arboreum (Allman, 1888) (Fig. 14 h–j) Material examined. ANT XV/3 : 48-36 , one colony, up to 80 mm high; ANT XVII/3 : 111-5 , one colony, c. 40 mm high; 111-6 , several stems, c. 140 mm high, on stone, with gonothecae; 111-7 , several stems, up to 120 mm high, and few stems, up to 6 mm high, on O. terranovae 111-9 , several stems, up to 110 mm high, with gonothecae; 111- 18 , one colony, c. 135 mm high, with gonothecae; 111-19 , one colony, c. 20 mm high; ANT XXI/2 : PS65/39 , a few stems, up to 33 mm high; PS65/278 , one colony, c. 50 mm high; PS65/279 , few stems, up to 35 mm high, on sponge; PS65/280 , one colony, c. 20 mm high; PS65/281 , some stems c. 80 mm high. Ecology and distribution. Species collected between 18 (Hickson & Gravely 1907, as Halecium arboreum ) and 1370 m depth (Peña Cantero & Ramil 2006); present material at 62– 175 m. Pan-Antarctic species widely distributed in Antarctic and sub-Antarctic waters (Peña Cantero & Ramil 2006). Documented in the Weddell Sea by means of remote operate vehicle (Dimmler et al. 2001), present contribution constitutes the first verifiable record from this Antarctic region. 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 43, DOI:10.11646/zootaxa.4570.1.1, http://zenodo.org/record/2608527 |
