Abstract
Ascarophis arctica Poljansky, 1952 (Nematoda: Cystidicolidae) is described. The parasites were obtained mainly from the four-horn sculpin, Myoxocephalus quadricornis (L.), from the northern Baltic Sea, but also from Zoarces viviparus (L.) from the southern Baltic. The description is based on LM and SEM studies. Worms were found close to the mucosa of the distal part of the stomach. The fact that Ascarophis arctica is common in the four-horn sculpin suggests that in the Baltic Sea it is a glacial relict. The record of this species in Zoarces viviparus does cast some doubt upon this view.
