Bimeria corynopsis Vanhöffen, 1910 (Fig. 2 a–c) Material examined. ANT XV/3 : 48-150 , stolonal colony up to 1 mm high, with two polyps, on Eudendrium scotti Puce, Cerrano & Bavestrello, 2002. Remarks. In spite of being scarce, our material perfectly agrees with the description of the syntypes examined by Peña Cantero (2015), including the slightly-capitate appearance of tentacles (Fig. 2c), which has been considered as the diagnostic trait of the species (see Schuchert 2007). Cnidome consisting in microbasic euryteles [range 7.5– 9 x 5.0–5.5 µm, mean 8.6±0.5 x 5.2±0.3 µm (n=21)] and desmonemes [range 4.5–5.0 x 3.0–3.5 µm, mean 4.7±0.4 x 3.3±0.3 µm (n=16)]. Ecology and distribution. Previously found at depths between 231 (Peña Cantero 2017) and 527 m (Peña Cantero 2014a); present material at 710– 758 m. Hitherto considered as endemic of East Antarctica (Peña Cantero 2014a); present finding, the fourth report of the species, and the first for both the Weddell Sea and West Antarctica, points to a circum-Antarctic distribution.
