From the testis two morphologically dissimilar vasa deferentia depart. One is of the normal construction; thin-walled and distally widening to a seminal vesicle, which is lined with a membranous, nucleated epithelium. The other vas deferens is enlarged and is surrounded by a layer of very thick, longitudinal muscles. It is 190–260 μm long. The seminal vesicle and the modified vas deferens join each other distally to form the ejaculatory duct, which enters the copulatory bulb. The copulatory organ is of the conjuncta-duplex

Proximally it receives some eosinophilic and basophilic glands. The epithelium is high and the common genital atrium is surrounded by longitudinal muscles over its entire length. Distally, it narrows again to broaden a second time just before it reaches the gonopore. This is situated at 80% and surrounded by a sphincter.</paragraph>

The caudally-situated female bursa is connected to the ovary by a broad duct consisting of bursal tissue. A separate spermatic duct was not observed. The bursa contains numerous optically-clear vacuoles. An external vagina is connected to the bursa and has a thick, sclerotized wall. It widens to a spherical space just proximally from the vaginal opening. The vaginal opening is situated rostrally from the gonopore. At the place where the external vagina enters the bursa, a separate seminal receptacle is also connected to the bursa. This seminal receptacle is elliptical and is surrounded by circular muscles.</paragraph>
