Abstract
    Specimens belonging to the pycnogonid family Ammotheidae collected during the Victoria Land Transect 2004 cruise (Ross Sea, Antarctica) were studied. Five species are recognized in this collection, three species of Ammothea, one of Achelia and one of Austroraptus. Some information about the variability of the propodal armature of Ammothea glacialis is discussed. The rare species Ammothea meridionalis is reported for the fifth time, enlarging its known bathymetric range. A new species in the genus Ammothea is described, Ammothea victoriae. The new taxon is compared with its closest congeners, especially with A. armentis, A. gordonae and A. carolinensis. Both morphotypes of Achelia spicata are reported, some additional morphological differences having been detected between them. Austroraptus calcaratus is reported for the third time, and with our specimens 14 individuals are now known. Present and previous data show a restricted geographical and bathymetric distribution.
