Additional data on the details of the male terminalia of Antarctic representatives of the genera Lepidapedon Stafford, 1904 and Neolepidapedon Manter, 1954 are given. The cirrus sac or its distal part of a "Lepidapedon-type" was found in 6 species, L. garrardi (Leiper et Atkinson, 1914), L. notogeorgianus Zdzitowiecki, 1990, L. paralebouri Zdzitowiecki, 1990, L. tertius Zdzitowiecki, 1990, N. magnatestis (Gaevskaya et Kovaljova, 1976) and N. trematomi Prudhoe et Bray, 1973. A new genus, Postlepidapedon, is erected, with P. opisthobifurcatus (Zdzitowiecki, 1990) relegated from the genus Neolepidapedon, as a type-species. The genus is distinguished from related genera in the intestinal bifurcation at the posterior margin of the ventral sucker, lack of the pseudoesophagus, the cirrus sac similar to a "Opechona-type" and the excretory vesicle reaching the anterior testis. Muraenolepitrema magnatestis Gaevskaya et Rodjuk, 1988 is redescribed.
