Testes are mainly ventral and ovaries are dispersed dorsally. A pair of free prostatic vesicles of free-type is present. The unique seminal vesicle receives the two prostatic canals and communicates with the ejaculatory duct which leads to a penis papillae armed with a stylet. The two gonopores are separated. The vagina shows a widening, the cement pouch and then curve dorsally where it receives the uteri.
