The taxonomic position of Cystidicola marina Szidat, 1961 is revised, based on the re-examination of type and new specimens collected fr om the type host, Urophycis brasiliensis (Gadidae), and a new host, Paron a signata (Carangidae), in the southwestern Atlantic. The species is r edescribed and transferred to Ascarophis as A. marina n. comb. It is d istinguished from other species of Ascarophis by the following combina tion of characters: body length (male: 10.2-22.5 mm, female: 32.8-44.2 mm), number of egg filaments (2 on each pole), egg size (0.030-0.039 mm x 0.015-0.021 mm), and left spicule length (0.4-0.6 mm).
