Abstract

Placopsis antarctica, which is apparently endemic to antarctic regions south of lat. 60°S (South Orkney Is, South Shetland Is and the Antarctic Peninsula), is described. Details of its morphology, anatomy, chemistry, ecology and distribution are given. Placopsis bicolor is newly reported from South Georgia. A revised key to species of Placopsis occurring in South Georgia and Antarctica is given.
