Abstract

<abstract abstract-type="author" id="abs0005"> <title id="sect0005">Abstract</title> <sec> <p id="spar0005">The ultrastructural organization of the spermatozoon of the digenean <italic>Tergestia acanthocephala</italic> (Gymnophalloidea: Fellodistomidae) is described. Live digeneans were collected from <italic>Belone belone gracilis</italic> (Teleostei: Belonidae), caught off the Gulf of Gabès in Chebba (Tunisia). The mature spermatozoon of <italic>T. acanthocephala</italic> exhibits the general pattern described in numerous digeneans, characterized by the presence of two axonemes of the different length of the 9 + '1' pattern of the Trepaxonemata, a nucleus, two mitochondria, two bundles of parallel cortical microtubules, external ornamentation, spine-like bodies and granules of glycogen. Moreover, the morphology of the posterior spermatozoon extremity in <italic>T. acanthocephala</italic> corresponds to the fasciolidean type of <xref id="crf0045" rid="bib0210">Quilichini et al.
