Vitellogenesis in two spathebothriidean cestodes
The ultrastructural features of vitellogenesis in spathebothriideans resemble those reported previously in “lower” cestodes, especially in pseudophyllideans.
Spermiogenesis in the caryophyllidean cestode Khawia armeniaca (Cholodkovski, 1915)
Ulastructural data of spermiogenesis in K. armeniaca may support the hypothesis that the Caryophyllidea are secondarily derived from an ancestor closely allied with the Pseudophyllides and/or spathebothriideans.
Vitellocyte ultrastructure in the cestode Didymobothrium rudolphii (Monticelli, 1890): possible evidence for the recognition of divergent taxa within the Spathebothriidea
The comparative data demonstrate that vitelline material morphology has unique features in three spathenothriidean genera and may be used as evidence for the recognition of separate taxa.
On the Position of Archigetes and Its Bearing on the Early Evolution of the Tapeworms
Phylogenetic analyses favor the interpretation that sexual maturity of Archigetes sp.
Vitellogenesis and vitelline system in the pseudophyllidean tapeworm Paraechinophallus japonicus: ultrastructural and cytochemical studies.
The vitellogenesis of Paraechinophallus japonicus (Yamaguti, 1934), the first pseudophyllidean tapeworm of the family Echinophallidae studied using transmission electron microscope, is described on…
Spermatological characters in Diphyllobothrium latum (Cestoda, Pseudophyllidea)
The spermatological data support the assumption that the order Pseudophyllidea is formed by two unrelated clades, “Bothriocephalidea” and “Diphyllobothriidea", mainly in the absence of a crested body and a ring of electron‐dense tubular structures.
Host specificity, molecular phylogeny and morphological differences of Phyllodistomum pseudofolium Nybelin, 1926 and Phyllodistomum angulatum Linstow, 1907 (Trematoda: Gorgoderidae) with notes on…

The results lead to the perception that macroevolutionary host switching in the genus Phyllodistomum is independent of host phylogeny, and strict host-specificity (oioxeny) for P. pseudofolium is suggested.
Spermatological characters of the pseudophyllidean cestode Bothriocephalus scorpii (Müller, 1776).
Ultrastructural features of the spermatozoon and its differentiation in Brandesia turgida (Brandes, 1888) (Digenea, Microphalloidea, Pleurogenidae)
Variations of the spermatozoa ultrastructural characters within Digenea, in particular, between different families of the superfamily Microphalloidea, are discussed.
Redescription of Eubothrium fragile (Rudolphi, 1802) and E. rugosum (Batsch, 1786) (Cestoda: Pseudophyllidea), parasites of fish in the Holarctic Region.
Two fish cestodes, the little-known Eubothrium fragile (Rudolphi, 1802) and E. rugosum (Batsch, 1786) are redescribed on the basis of new material from twaite shad, Alosa fallax (Lacépède, 1803) and burbot, Lota lota (Linnaeus, 1758), from Russia, respectively.
