The anatomy of Köllikeria filicollis (Rudolphi, 1819), Cobbold, 1860 (Trematoda: Digenea) is described in detail.
An account is given of the integument and musculature of the worm and the structure of the cyst in which it is found, followed by a discussion of the body wall in other digenetic trematodes. The alimentary canal, excretory system, nervous system and genitalia are also described.
The study shows that the sexes are not entirely separate in all members of the genus Köllikeria as hitherto believed.
The systematic position of K. filicollis is discussed and a specific diagnosis is given for the species.
