Genital pores situated in first third of length of lateral proglottis margin, alternating irregularly in small series (i.e. 3, 2, 1, 3), up to 6 consecutive pores on same side observed. Ventral osmoregulatory canals connected posteriorly in each proglottis by transverse anastomosis. Genital ducts passing between osmoregulatory canals.

These genera differ from one another essentially by the structure of their uterus, with or without capsules, a character, which we cannot determine in the present material due to the lack of gravid proglottides. A few other diagnostic characters are given by
