Abstract

Records of 13 trematode species, collected from bottom fishes from the western and northern parts of the Ross Sea, are given. Trematodes Otodistomum cestoides van Beneden, 1871, Lecithaster micropsi Zdzitowiecki, 1992, Neolepidapedon trematomi Prudhoe et Bray, 1973, Postlepidapedon opisthobifurcatum (Zdzitowiecki, 1990), Discov- erytrema gibsoni Zdzitowiecki, 1990, D. markowskii Gibson, 1976, Macvicaria muraenol- epidis Zdzitowiecki, 1990, Helicometra rakusai Zdzitowiecki, 1997 and Proctophantastes sp. are recorded from the Ross Sea for the first time. Proctophantastes sp. differs from other species of Proctophantastes Odhner, 1911 by the morphology of the ventral equatorial ridge of the ventral sucker.
