"This paper provides the first ultrastructural data on the spermatozoon of a pseudophyllidean cestode belonging to the family Echinophallidae, Paraechinophallus japonicus, parasitizing deep-sea fish Psenopis anomala from Japan. One of the most interesting features of the mature spermatozoon is the presence of a ring of tubular structures encircling axoneme. This character, previously reported in species of the families Bothriocephalidae and Triaenophoridae, may be unique to pseudophylideans of the group \u201CBothriocephalidea\u201D, thus supporting the assumption that the order Pseudophyllidea is formed in fact by two unrelated clades; \u201CBothriocephalidea\u201D and \u201CDiphyllobothriidea\u201D. The posterior extremity contains the posterior part of the nucleus and the disorganized axoneme, a character previously not described in the Eucestoda."@en . "5"^^ . . . . "1" . . .
