( Fig. 10a )

Material examined. ANT XV/3: 48-72, one colony, c. 65 mm high, with developing gonothecae; ANT XXI/2: PS65/121, one colony, c. 50 mm high; PS65/237, one colony, 11 mm high.

Ecology and distribution. Previously reported at depths from 18 (Peña Cantero et al. 2017) to 429 m ( Peña Cantero 2008); material examined comes from 230 to 274 m. Circum-Antarctic species (Peña Cantero et al. 2017); present contribution constitutes the first evidence from the Weddell Sea.
