( Fig. 6View FIGURE 6 c–f)

Material examined. ANT XV/3: 48-5, numerous hydrothecae, on S. lobata  , with coppinia; ANT XVII /3: 111-9,

several hydrothecae, on S. lobata  , with coppinia; ANT XXI /2: PS65/276, numerous hydrothecae, on St. vanhoeffeni  , with coppinia.

Remarks. Cnidome comprising large microbasic mastigophores [range 10.0–12.0 x 4.0–4.5 µm, mean 10.9±0.8 x 4.1±0.2 µm (n=11)] and small microbasic euryteles [range 5.5–6.5 x 2.5–3.0 µm, mean 6.1±0.3 x 2.8±0.3 µm (n=18)].

Ecology and distribution. Species previously reported in Antarctic waters at depths from 42 ( Stepanjants 1979) to 1658 m (Peña Cantero in press); present material from 62 to 277 m. Species known from all over Antarctic waters (Peña Cantero et al. 2004) and South Africa ( Millard 1964, 1975).
