is gonochoristic. Both in female and males gametes develop from chaetiger 17 to chaetigers 50–55. Oogenesis is intraovarian. Vitellogenic oocytes develop in ovaries attached to segmental blood vessels. Intraovarian oocytes were up to 90 µm in diameter, with germinal vesicle about 50 µm and single nucleolus 18 µm in diameter. Oocyte envelope is 2–3 µm thick, with smooth external surface. Developed coelomic oocytes were about 140 µm in diameter, with germinal vesicle about 60 µm and single nucleolus 20 µm in diameter (
