Abstract
This paper describes the ultrastructure of spermiogenesis and the spermatozoon of Leptorhynchoides plagicephalus, an acanthocephalan parasite of the sturgeon Acipenser naccarii, a species which is under the threat of extinction. At the beginning, spermiogenesis in L. plagicephalus is characterized by the presence of a single centriole in the early spermatid. This centriole generates a flagellum with a 9+0 pattern. Another ultrastructural feature observed during the spermiogenesis of L. plagicephalus is the condensation of chromatin to form an "intranuclear wall". The mature spermatozoon of L. plagicephalus presents a reversed anatomy, as observed in other species of the Acanthocephala. The spermatozoon is divided into two parts: an axoneme and a nucleocytoplasmic derivative. The pattern of spermiogenesis and the ultrastructural organization of the spermatozoon of L. plagicephalus are compared with information available on other acanthocephalan species. The appearance of an "intranuclear wall" observed during the present study represents the first record within the Acanthocephala and is unknown from other animal taxa.
