ANTARCTURUS-BOVINUS N-SP, A NEW WEDDELL-SEA ISOPOD OF THE FAMILY ARCTURIDAE (ISOPODA, VALVIFERA)

Antarcturus bovinus n. sp. (Isopoda, Valvifera) is described from the Antarctic Peninsula and the western and southern Weddell-Sea. This species can easily be recognized by the absence of large spines, the spine armature of the dorsal surface characteristic of other species is lacking. Only A. antarcticus Bouvier, 1910, A. coppingeri Miers, 1881, A. granulosus Nordenstam, 1933 and A. lilliei Tattersall, 1921 are similar, but A. bovinus n. sp. can be discerned from these by the presence of blunt supraocular spines.
