Three lepocreadiid species are described as new: Lepidapedon brayi sp. n., L. ninae sp. n. and Paralepidapedon awii sp. n. Some morphological data for other species are given. Postlepidapedon opisthobifurcatus (Zdzitowiecki, 1990) and Glomericirrus macrouri (Gaevskaya, 1975) are reported from the high Antarctic for the first time and in new hosts. Gonocerca phycidis Manter, 1925 is found in a new host. The total number of digenean species recorded in M. whitsoni increased from 2 to 8.
