A and C) there are 20–30 testes from some distance behind the brain to the level of the pharynx glands; the most anterior (and smaller) testes are in a single row, while those more towards the pharynx are in two alternating rows. Two large seminal vesicles, filled with unusually thick sperm, are in the very caudal end of the animal and enter the prostate vesicle laterally through S-shaped seminal ducts. The prostate vesicle, with coarse basophilic glands proximally and fine eosinophilic glands distally, continues with a duct, the epithelium of which is much thicker dorsally than ventrally. This duct protrudes as a penis papilla in a ring of ±60 atrial needles. There are weak spiral muscles around the prostate vesicle, but no muscles were detected around the duct that forms the penis papilla. The atrial needles (

the five “adult” males in the whole mounts. The length of the needles varies from 130 to 180µm and they are about 45µm in the two developing males. They end in a strong hook; at the base of each hook is inserted a bundle of muscles that originates from the proximal end of the needle. In front of the copulatory organ there is a large oval accessory glandular organ in the male atrium, about 300x460 to 360x730µm (measured in the whole mounts). Towards the atrium it is covered by a cuboidal hyaline epithelium. The central area of the organ is depressed, the whole organ forming a kind of sucker. The central area of the basement membrane under the epithelium is thick with some weak muscles under it. Large basophilic and eosinophilic glands open at the right and left sides of the sucker-like depression. The rest of the atrium is covered with a low epithelium and the male pore is guarded by a small sphincter.

B, D and E) the ovaries, lying in front of the pharynx glands, are very large, C-shaped. The vitellaria start at some distance behind the brain and continue until about midway between the pharynx and the caudal end, with seven to eight post-pharyngeal follicles. The ovovitelloducts enter the short female duct (±65µm long) from both sides. The cement glands are highly developed and enter the female duct over its entire length. Anteriorly they almost reach the last vitellarian follicle; posteriorly they reach the caudal end, where they are mixed with the row of adhesive glands.

On the other hand, in two of the developing females remnants of the male system were seen in the gut. In one of these individuals, the copulatory organ could clearly be recognised; in the other individuals there were some spines in the post-pharyngeal part of the gut that can be interpreted as partly resorbed needles of the copulatory organ. Probably the male organs are digested during the development of the female organs.</paragraph>
