| Summary: | Filellum cf. bouvetensis Marques, Peña Cantero, Miranda & Migotto, 2011 (Fig. 6h) Material examined. ANT XXI/2: PS65/39, some hydrothecae, on Sc. nana; PS65/121, several hydrothecae, on Sc. nana and B. subrufa; PS65/278, some hydrothecae, on A. elongatus. Remarks. The size spectrum of both the hydrotheca and the nematocysts are in agreement with the description of the species (cf. Marques et al. 2011). However, the absence of coppinia precludes a proper identification. Cnidome composed exclusively of microbasic mastigophores [range 6.5–9.0 x 3.0–3.5 µm, mean 7.4±0.7 x 3.2±0.3 µm (n=21)]. Ecology and distribution. Previously reported in Antarctic waters at a depth of 122–134 m [Peña Cantero & Gili 2006, as Filellum contortum (Nutting, 1905)]. Rare species only reported twice: from its type locality at Bouvet Island (Peña Cantero & Gili 2006) and from Gough Island, Tristan da Cunha archipelago, in the South Atlantic (Galea 2015). If confirmed, present record would constitute the first evidence 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 22, DOI: 10.11646/zootaxa.4570.1.1, http://zenodo.org/record/2608527 ... |
