Ascarophis marina n. comb. (Nematoda: cystidicolidae) from the fishes Parona signata (Carangidae) and Urophycis brasiliensis (Gadidae) in the southwestern Atlantic.
The taxonomic position of Cystidicola marina Szidat, 1961 is revised, based on the re-examination of type and new specimens collected from the type host, Urophycis brasiliensis (Gadidae), and a new host, Parona signata (Carangidae), in the southwestern Atlantic. The species is redescribed and transferred to Ascarophis as A. marina n. comb. It is distinguished from other species of Ascarophis by the following combination 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).
