摘要：

The ultrastructure of the male genital tract of P. moseleyi was examined under the EM. In the testes somatic cells, spermatogonia and spermatocytes occur. In the spermatocytes electron-dense granules are built by the Golgi-apparatus. They are released from the developing spermatid and can still be detected in the spermatophore. Spermiogenesis takes place in the seminal vesicles. Nuclear condensation and elongation, and formation of the middle piece and acrosome are described. The mature sperm cell has an elongated nucleus, a middle piece containing mitochondria only and a tail with 9 + 2-formation and accessory microtubule systems. The spermatophore is formed within the vas deferens the epithelial cells of which secrete great amounts of material enveloping the sperm mass.
