The copulatory bulb is surrounded by a thick, inner, spirally-running to circular muscle layer and outer longitudinal muscles. The prostate vesicle is also surrounded by longitudinal muscles. Distal to the copulatory bulb, a pincers-shaped stylet is present. It consists of a common base from which two separate, curved arms depart. The longest of these arms is 44–49 µm long and hollow. It is filled with the prostate secretion that proximally enters the stylet. The shortest arm is 20–27 µm long and seems to be an accessory outgrowth of the longer arm's wall. From the base to the distal apex of the longest arm, the stylet measures 54–59 μm. The base of the stylet has a proximal rim and is connected to the copulatory bulb.</paragraph>

Distally it opens into the common genital atrium. The bursa copulatrix is a sack-shaped protrusion of the common genital atrium and is filled with spermatozoa. It runs dorsally from the male atrium and has a very broad connection with the common atrium. In consequence, differentiation between the bursa copulatrix and the common atrium is not always clear. The bursa copulatrix and the male genital atrium are lined with a relatively high, anucleated epithelium and surrounded by a weaklydeveloped circular muscle layer. The gonopore is at about 75% and surrounded by a sphincter.</paragraph>

At the place of entry, a strong sphincter is present. This female duct is relatively short and broad, lined with a high, nucleated epithelium and surrounded by a strongly-developed circular muscle layer. The lumen is filled with spermatozoa. Proximally, both oviducts and a bundle of eosinophilic glands enter the female duct. The oviducts are very short and lined with a membranous epithelium. Ventrally from the oviducts, a seminal bursa opens into the female duct through a sphincter. The seminal bursa is spherical to club-shaped and has a fairly long bursal stalk. It is lined with a membranous epithelium. The bursa contains sperm, which are thinner and less darkly-stained than the sperm found elsewhere in the animal. A uterus is absent.</paragraph>
