New Information and Locality Records for the Antarctic Amphipod Clarencia Chelata K. H. Barnard, 1931, and a Reappraisal of the Family Clarenciidae J. L. Barnard & Karaman, 1987 (Amphipoda, Gammaridea)

An examination of fresh material of Clarencia chelata K. H. Barnard, 1931, collected from the Prydz Bay region, Antarctica, has revealed a number of characters not recognised previously or diagnosed incorrectly. New morphological information is provided and the systematic position of Clarenciidae is re-evaluated and a new superfamily Clarencioidea is proposed. A new diagnosis for Clarenciidae is also provided. The species seems to be associated with the white sponge Asbestopluma belgicae (Topsent, 1901) (Cladorhizidae).
