Treatment

Halecium incertus Naumov & Stepanjants, 1962 View in CoL

( Fig. 13 View FIGURE 13 f–g, 14a)

Material examined. ANT XXI/2: PS65/121, one colony, c. 220 mm high, on gravel, with female gonothecae; PS65/248, one colony, c. 260 mm high, on stone, with female gonothecae.

Ecology and distribution. In Antarctic waters, reported at depths from 15 ( Stepanjants 1979) to 527 m ( Peña Cantero 2014a); present material at 268– 287 m. Species with Antarctic–Kerguélen distribution ( Peña Cantero & Gili 2006). This new report constitutes the first evidence from both the Weddell Sea and West Antarctica.
