The morphology of a new marine heliozoan from the sandy littoral of King George Island (the South Shetland Islands, Antarctica) is described. The species is characterized by bent or curved spicules with a spur at the shaft bend point. Similarities and differences between the new species and other representatives of the genus Choanocystis are considered.
