The genital tract and the spermatogenesis of a free-living cyclopoid copepod, Acanthocyclops viridis, has been studied. The testis is simple and lies in the dorsal region of the cephalothorax, as in other Copepoda. Two vasa deferentia leave the testis at the frontal end before joining the disto-anterior part of the spermatophore pouch. The wall of the proximal part of the vasa deferentia has great secretory activity, producing the substance of the core of the spermatophore. The middle part secretes the peripheral substance and the coat. No fundamental differences between the spermatogenesis in Acanthocyclops and certain parasitic copepods have been observed. The spermatozoon of Acanthocyclops is an immobile, disk-shaped gamete surrounded by a cytoplasmic lamina, showing strong modifications. A comparative analysis of sperm cells of various Copepoda leads to the conclusion that their morphology correlates better with their reproductive biology than with their taxonomic classification.
