Two genital pores are evident in the ventral face, between them and closer to the female pore is the genital pit. The genital pit is a depression of the ventral wall of epidermal nature, also known as genital sucker (Rawlinson et al 2008), but not comparable with the true sucker of the Cotylea due to a lack of characteristic muscle-layers and the position between the genital openings instead of posterior to them (

F; 2E). There is no musculature between the prostatic and the seminal vesicle. The median section of the prostatic vesicle is orientated dorsally and opens into the dorso-distal region of the seminal vesicle via a narrow opening. The lumen of the distal section of the prostatic vesicle forms a small chamber which opens to the proximal part of the ejaculatory duct, the unarmed penis cirrus. The latter leads to the male atrium that shows a dorso-posteriorly oriented diverticulum. This diverticulum is of various sizes and can reach half of the animal's thickness in some specimens. The male genital pore is wider than the female one.
