Abstract
This study provides the first ultrastructural data on the mature spermatozoon of Aephnidiogenes senegalensis (Digenea, Lepocreadioidea, Aephnidiogenidae) parasite of the teleost fish Pomadasys jubelini (Haemulidae) captured near the coast of Dakar (Senegal). This is also the first ultrastructural data on the spermatozoon in the genus Aephnidiogenes. The mature spermatozoon of A. senegalensis is filiform, tapered at both ends and exhibits the general pattern described in the Lepocreadioidea, namely two axonemes of the 9 + '1' pattern, an antero-lateral electron dense material, a nucleus, two mitochondria, external ornamentation of the plasma membrane in the anterior region of the spermatozoon, granules of glycogen and two bundles of parallel cortical microtubules. A peculiarity of the spermatozoon of A. senegalensis is the structure of the apical electron-dense material.
