Filellum antarcticum (Hartlaub, 1904) Reticularia antarctica — Totton, 1930: 160 –161, fig. 17. Filellum antarcticum— Peña Cantero et al., 2004: 2283–2287 figs 2C–F, 3, 4 (synonymy); Peña Cantero, 2008: 453; 2010b: 764–765, fig. 3a–c; 2012: 856–557; 2013: 127–128; 2014a: 1717. Material examined. Stn 130, numerous hydrothecae on Billardia subrufa (Jäderholm, 1904), with coppiniae (NIWA 117487); Stn 132, several hydrothecae on Billardia subrufa, with coppiniae (MNCN 2.03/533). Measurements (in µm). Hydrotheca: diameter at aperture 100–150. Cnidome: larger size group (12.0–15.0 x 4.0–5.0); smaller size group (6.0 x 3.0). Remarks. As typical for this species, the defensive tubes of the coppinia surround the gonothecae and create a breeding chamber; the defensive tubes are provided with a distal aperture. Also characteristically, gonothecae are deprived of distal neck. Hydrotheca with striae on the upper side of adnate part. Ecology and distribution. Shelf species (Peña Cantero et al. 1998), found at depths ... : Published as part of ÁLVARO L.
