Diacyclops (Copepoda: Cyclopoida) in Continental Antarctica, including three new species
Abstract Contrary to earlier beliefs, crustaceans are present in ice-covered lakes of Antarctica. Interpretation of the significance of this has been hampered by the absence of robust identification of taxa present. We examine cyclopoid copepods from three widely separated lakes. All belong to the m...

Abstract Contrary to earlier beliefs, crustaceans are present in ice-covered lakes of Antarctica.

Two new species were identified from eastern Antarctica, D. walkeri from Pineapple Lake (Vestfold Hills) and D. kaupi from Transkriptsii Gulf (Bunger Hills).
