Summary: | Three Ampelisca species (fam. Ampeliscidae) from Antarctic waters (Arthur Harbor, Anvers Island) are studied and described: A. anversensis n. sp., A. bouvieri Chevreux, 1913, and A. richardsoni n. sp.\nThe specimens of A. anversensis are considered the Antarctic counterpart of the species A. macrocephala Liljeborg, 1852. A. richardsoni was hitherto confused with A. eschrichtii Kr\xc3\xb8yer, 1842. A new locality for A. bouvieri is established.\nIn establishing differences between Antarctic populations (anversensis n. sp., richardsoni n. sp.) and North Atlantic populations (macrocephala, eschrichtii), the non-existence of bipolar Ampelisca species is proved.
