Three lepocreadiid digenean species of two genera, Neolepidapedon Manter, 1954 and Lepidapedon Stafford, 1904, occur in notothenioid fishes of the genera Trematomus (Nototheniidae), Artedidraco and Pogonophryne (both Artedidraconidae), Bathydraco and Prionodraco (both Bathydraconidae) in the Weddell Sea. Descriptions of all species, including a new one and two previously recorded in the high Antarctic, are given. Neolepidapedon trematomi Prudhoe et Bray, 1973 is recorded in 4 host species, three of the genus Trematomus (2 new host species) and Pogonophryne permitini (new host species and family), for the first time in the Weddell Sea and south to 70°S. Lepidapedon garrardi (Leiper et Atkinson, 1914) and L. balgueriasi sp. n. belong to the “Beveridgei subgroup” of Bray and Gibson (1995). L. garrardi has the excretory vesicle reaching to the level of the border between the testes and it is transferred to this subgroup from the “Garrardi subgroup”, which is renamed to the “Zubchenkoi subgroup”. This species is recorded in 9 host species (7 new hosts), for the first time in the Weddell Sea. L. balgueriasi sp. n. is recorded in 4 species of the genus Trematomus, including T. loennbergi (type-host). This species has eggs similar in number and size to L. garrardi (egg length exceeding 0.1 mm), but it has relatively smaller suckers and pharynx, and vitelline follicles confluent in the forebody and dorsally to the testes; its site is in the pyloric caeca and anterior part of the small intestine. A key to species of the “Beveridgei subgroup” of the genus Lepidapedon is given.
