Branchiae on chaetiger 5 slightly flattened to cylindrical, slightly longer than branchiae on previous chaetigers, each with up to 15 pairs of digitiform pinnules arranged on inner lateral and posterior sides; short apinnate branchiae on this chaetiger in some large individuals probably resulted from regenerating after occasional lost. Each branchia with longitudinal bands of cilia along inner and outer edges. Afferent and efferent branchial blood vessels interconnected by numerous radial capillaries giving branchiae annulate appearance; radial capillaries forming loops inside pinnae in fourth pair of branchiae.

is gonochoristic. Both in females and males gametes develop from chaetigers 12–13 to chaetigers 36–40. Oogenesis is intraovarian. Vitellogenic oocytes develop in ovaries attached to segmental blood vessels. Intraovarian oocytes were up to 110 µm in diameter, with germinal vesicle about 50 µm and single nucleolus 17 µm in diameter. Oocyte envelope is about 1 µm thick. Spermatogonia proliferate in testes; spermatogenesis occurs in the coelomic cavity. Spermatids are joined in tetrads. Spermatozoa are ect-aquasperm with small acrosome, spherical nucleus 2–3 µm in diameter, spherical mitochondria probably four in number, and a long flagellum.
