Abstract. Spermiogenesis of the pseudophyllidean tapeworm Eubothrium crassum has been described by the aid of transmission electron microscopy for the first time. Initially, early spermatids form a distal cytoplasmic protrusion, a differentiation zone containing a small electron-dense, apically oriented region. Out of this region, two centrioles with rootlets develop. The centrioles become orientated in the same plane with the appearance of an intercentriolar body. Now, the long axes of the… Expand
Spermiogenesis in the proteocephalidean cestode Proteocephalus torulosus (Batsch, 1786)
Spermiogenesis of the proteocephalidean cestode Proteocephalus torulosus was examined for the first time using transmission electron microscopy and the advanced spermatids detach from a condensing residual cytoplasm at the level of the arching membranes. Expand
Spermiogenesis in the cestode Corallobothrium solidum Fritsch, 1886 (Proteocephalidea: Corallobothriinae)
The present results support previous data that the type of spermiogenesis in proteocephalideans resembles mostly that observed in tetraphyllideans (Onchobothriidae and Phyllobothriaidae), thus supporting the view of a close phylogenetic relationship of tetraphytidean and proteOcephalidean cestodes.

Spermatological characters of the pseudophyllidean cestode Bothriocephalus scorpii (Müller, 1776).
The organization of the posterior extremity of the gamete with the nucleus is described for the first time in the Pseudophyllidea and appears to be a specific feature for the clade "Bothriocephalidea". Expand
A reinvestigation of spermiogenesis in Amphilina foliacea (Platyhelminthes: Amphilinidea).
New for this species is the finding of electron-dense material in the apical region of the differentiation zone at the early stage of spermiogenesis, and the fact that two arching membranes appear at the base of the differentiated zone only when the two flagella rotate towards the median cytoplasmic process.

Ultrastructural study of spermiogenesis and the spermatozoon of the proteocephalidean cestode Barsonella lafoni de Chambrier et al., 2009, a parasite of the catfish Clarias gariepinus (Burchell, 1822) (Siluriformes, Clariidae)
The mature spermatozoon presents two axonemes of the 9 + ‘1’ trepaxonematan pattern, crested body, parallel nucleus and cortical microtubules, and glycogen granules, which corresponds to the type II spermatoZoon, described in almost all Proteocephalidea. Expand
Spermiogenesis and sperm ultrastructure of the pseudophyllidean cestode Triaenophorus nodulosus (Pallas, 1781)
Spermiogenesis and ultrastructure of the spermatozoon of the pseudophyllidean cestode Triaenophorus nodulosus (Pallas, 1781), a parasite of pike Esox lucius, has been studied by transmission electronExpand
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. Expand
Ultrastructure of spermiogenesis in the caryophyllidean cestode Wenyonia virilis Woodland, 1923, with re-assessment of flagellar rotation in Glaridacris catostomi Cooper, 1920
The ultrastructure of spermiogenesis in Wenyonia virilis Woodland, 1923, a caryophyllaeid cestode from the silurid Nile fish Synodontis schall, is described by means of transmission electron microscopy for the first time and it is concluded that flagellar rotation must logically occur in that species.

Spermatological characters of the spathebothriidean tapeworm Didymobothrium rudolphii (Monticelli, 1890)
The ultrastructural features of the sperm/spermiogenesis support a view about the close relationships of the Spathebothriidea and DiphyllobothriideA and the basal position of thespathebothRIidea within the Eucestoda. Expand
Ultrastructure of the spermatozoon of the pseudophyllidean cestode Eubothrium crassum (Bloch, 1779)
The results reveal several peculiarities, in which the spermatozoon of E. crassum differs from those of other pseudophyllidean cestodes. Expand
