Morphology of the reproductive system of female Moniliformis dubius (Acanthocephala).

By means of light and electron microscopical techniques, the organization of the reproductive tract of female Moniliformis dubius is described. The tract consists of an efferent duct system associated with 2 ligament sacs present in the body cavity. The efferent duct system consists of uterine bell, uterus and vagina. The uterine bell contains a complex system of routes and is associated with the ligament sacs in a way that facilitates egg sorting. The dorsal and ventral ligament sacs exist with separate cavities at the posterior end, where they are attached to the efferent duct, but merge into a single sac at the anterior of the trunk.
