Abstract: | The ultrastructural characteristics of the mature spermatozoon of the aspidogastrean Rohdella amazonica (Aspidogastridae, Rohdellinae) were studied by means of transmission electron microscopy. The sperm cell shows two axonemes of the 9 + '1' trepaxonematan pattern of Platyhelminthes, parallel cortical microtubules, a well-developed lateral expansion, external ornamentation of the plasma membrane, one mitochondrion, an electron-dense ring, a nucleus and granules of glycogen. The present results were compared with those observed in the aspidogastreans studied to date and in other Platyhelminthes. The lateral expansion and the electron-dense ring are typical characters for aspidogastreans. Although a lateral expansion has been described in other Platyhelminthes such as monogeneans and digeneans, the Aspidogastrea shows a much larger lateral expansion with both peripheral and internal microtubules. The dense ring is observed as a cylinder in a longitudinal view and shows a more granular appearance in sperm cells from the seminal vesicle in comparison to a more electron-dense appearance in sperm cells from the seminal uterine receptacle. |
