Misophrioid copepods are reported for the first time from Antarctic waters. A species of each of the genera Misophriopsis and Misophriella is described from hyperbenthic layers of the continental shelf of the eastern Weddell Sea. The genus Misophria is also reported from these waters. Misophriopsis australis sp. nov. is the fifth representative of this widely distributed genus, previously reported from the North Atlantic, the China Sea, and both NW and NE quadrants of the Pacific Ocean. Misophriella schminkei sp. nov. is the second representative of the genus, known to date only from a single female caught in North Atlantic bathyal depths. Traces of subdivisions on antennary exopodal segments of the latter species suggest that the first segment may be a triple segment, while the second and terminal segments may be double segments. In addition, the mandibular exopod of this taxon indicates that a six-segmented ramus with setal formula 0, 1, 1, 1, 1, 2 may represent the ground pattern in Copepoda. The presence of parts of a cyclopinid copepod in the gut of M. schminkei sp. nov. indicates that this species may be carnivorous This paper was a contribution to EC FAIR CT95-0655 and was supported by the Deutsche Forschungsgemeinschaft.
