In the present paper, we describe the ultrastructure of the spermatozoon of the notocotylid Notocotylus noyeri (Joyeux, 1922) by means of transmission electron microscopy. The mature spermatozoon of N. noyeri exhibits the general pattern described in the majority of digeneans: two axonemes of the 9 + "1" pattern of the Trepaxonemata, nucleus, mitochondria, parallel cortical microtubules, spine-like bodies and ornamentation of the plasma membrane. The glycogenic nature of the electron-dense… Expand

TLDR
The ultrastructural organization of the spermatozoon of the digenean Tergestia acanthocephala (Gymnophalloidea: Fellodistomidae) is described and corresponds to the fasciolidean type of Quilichini et al. (2010a). Expand

Sperm characteristics in the digenean Diplodiscus amphichrus (Paramphistomoidea, Diplodiscidae), a parasite of the Chinese edible frog Hoplobatrachus rugulosus
TLDR
Two characteristics of the male gamete of D. amphichrus were found for the first time in a digenean: the appearance of the initial part of the lateral expansion before the axonemes in the anterior extremity and the separation between the second axoneme and the nucleus in the posterior tip. Expand
Spermatozoon ultrastructure in two monorchiid digeneans
TLDR
The ultrastructural study reveals that the mature spermatozoon of Opisthomonorchis dinema and Paramonorcheides selaris share several characters that suggest a close phylogenetical relationship between the Monorchiidae and the Apocreadiidae, although more studies are needed, especially in the unexplored taxa. Expand
A comparative study of the ultrastructural characteristics of the mature spermatozoa of two fellodistomids Tergestia clonacantha and T. laticollis and contribution to the phylogenetic knowledge of the Gymnophalloidea
TLDR
It is confirmed that ultrastructural characters of the mature spermatozoon are useful tools for the phylogenetic analysis of the Digenea. Expand
Advances in Spermatological Characters in the Digenea: Review and Proposal of Spermatozoa Models and Their Phylogenetic Importance.
TLDR
The current knowledge about sperm structure in the digeneans is summarized and a classification of digenean spermatozoa into five basic models is proposed, which outline the most interesting features for phylogenetic inference and their possible value in the context of digenesan systematics, phylogeny and evolution.
