Stegella lobata ( Vanhöffen, 1910)

Material examined. E203, two stem fragments 50 and 55 mm long, with male gonothecae, basibiont of F. antarcticum ( NIWA 128467).

Remarks. Although only a few hydrothecae in bad condition are left, the typical colony structure allows a confident identification. The male gonotheca is roughly 1800 µm in height and 700 µm in maximum diameter.

Ecology and distribution. The material, which represents the first record of the species for the Balleny Islands, was collected at a depth of 187 m off Sturge Island.
