Neoascarophis macrouri n. sp. (Nematoda: Cystidicolidae) from the stomach of Macrourus berglax (Macrouridae) in the eastern Greenland Sea.
A new species of parasitic nematode, Neoascarophis macrouri n. sp. (Cystidicolidae), is described from the stomach and stomach wall of the marine deep-water fish Macrourus berglax (onion-eye grenadier) in the eastern Greenland Sea (North Atlantic Ocean). The new species, studied using both light and scanning electron microscopy, is characterised mainly by the location of the vulva near the posterior end of the body (a short distance anterior to the anus), non-filamented eggs, the structure of the mouth, a short vestibule and the length of the spicules (567-615 and 144-156 mum). Metabronema insulanum Solov'eva, 1991 is transferred to Neoascarophis as N. insulana (Solov'eva, 1991) n. comb.
