Spermatological characters of the digenean Brandesia turgida (Brandes, 1888), an intestinal parasite of the frog Pelophylax ridibundus (Pallas, 1771), have been investigated by means of transmission electron microscopy for the first time. The process of the spermatozoon formation begins with the appearance of the differentiation zone bordered by cortical microtubules and containing two centrioles associated with striated rootlets and with an intercentriolar body. The intercentriolar body is… Expand

The male gametes of Brachylecithum eliomydis a parasite of Eliomys querci-nus “the garden dormouse” caught in France were described by micrographs of transmission electronmicroscopy (TEM) and the general morphology of the spermatozoon described, could characterize the family Dicrocoeliidae. Expand

Ultrastructural study of sperm cells in Acanthocolpidae: the case of Stephanostomum murielae and Stephanostomoides tenuis (Digenea)
TLDR
The main ultrastructural characteristics discussed are the morphology of the anterior and posterior spermatozoon extremities, antero-lateral electron dense material, external ornamentations, spine-like bodies and number and morphology of mitochondria. Expand
Collyricloides massanae (Digenea, Collyriclidae): spermatozoon ultrastructure and phylogenetic importance
TLDR
The ultrastructural criteria described in C. massanae such as the morphology of both anterior and posterior spermatozoon extremities, the association “external ornamentation + cortical microtubules”, the type 2 of external ornamentation and the spine-like bodies would allow us to bring closer the Collyriclidae to Microphalloidea. 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.

TLDR
This study shows the ultrastructure of the mature spermatozoon of Lecithostaphylus parexocoeti, a parasite of the flying fish Cheilopogon pinnatibarbatus (Exocoetidae) captured in the Atlantic Ocean near Dakar (Senegal). Expand
