Two new Antarctic species of Schizotricha (Cnidaria: Hydrozoa: Leptothecata) from US Antarctic expeditions
2004
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.
Species ofSchizotrichaAllman, 1883 (Cnidaria: Hydrozoa: Halopterididae) from US Antarctic expeditions with the description of two new species
2005
Twelve species of the genus Schizotricha Allman have been studied, two of which are new to science (Schizotricha heteromera sp. nov. and S. trinematotheca sp. nov.). The material studied was collected by several US Antarctic expeditions. Each new species is described and figured, the systematic position amongst allied species discussed and available data concerning autecology and geographical distribution given. The remaining 10 species are considered regarding diagnosis, autecology and geographical distribution. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Schizotricha is given.
Two new antarctic species of the genus Schizotricha Allman, 1883 (Cnidaria, Hydrozoa)
1998
Two new antarctic species of the genus Schizotricha Allman have been studied. The material comes from the Scotia Sea (Antarctica) and was collected by the Spanish antarctic expedition `Antartida 8611'. Both species are described and figured and the systematic position is discussed. A general survey of the geographical and bathymetrical distribution of the antarctic and subantarctic species of the genus is given. Finally, a key for the identification of the antarctic and subantarctic species of the genus, together with a comparative table including main features, are presented.
