Two new Antarctic species of <i>Schizotricha</i> (Cnidaria: Hydrozoa: Leptothecata) from US Antarctic expeditions

Two species of the genus Schizotricha new to science (Schizotricha crassa sp. nov. and S. southgeorgiae sp. nov.) have been studied. Both species are described and figured and their systematic position amongst the remaining species of the genus is discussed. The material was collected during the United States Antarctic Research Programme (USARP) with RV ‘Eltanin’ and RV ‘Islas Orcadas’. A comparative table listing the main features and distribution of the known species of Schizotricha, together with an identification key, are presented
