A new nematode parasite, Esocinema bohemicum gen. et sp. nov.(Skrjabillanidae) of the European pike.

A new nematode genus and species, Esocinema bohemicum gen. et sp. nov., is described from the serosa of the air bladder of the pike (Esox lucius L.) from Czechoslovakia (North Bohemia). It is characterized largely by the tubiform buccal capsule, division of the oesophagus into the muscular and glandular sections, pointed tip of the female tail, and character of caudal papillae in the male. Agrachanus Tikhomirova, 1971 is considered a synonym of the genus Skrjabillanus Shigin et Shigina, 1958.
