Ultrastructural features of the female reproductive system and female gametes of Nectonema munidae Brinkmann 1930 (Nematomorpha).
Two stages of late juvenile females of Nectonema munidae Brinkmann, 1930 are described in terms of their productive system. In the first stage the body is filled with a tissue called the gono-parenchyme. Spherical compartments are separated into a central cavity. IN the second stage the body surrounds a large primary body cavity that contains a large quantity of oocytes and scattered nurse cells. Different types of vesicles occur in these structures. The present results are compared with the features known for the female reproductive system of species of Gordiida, the sister taxon of Nectonema within the Nematomorpha.
