Vitelline fields coalesce in anterior part of body anterior to ovary, and in posterior part of body posterior to testes; usually, there is break in vitelline fields at the level of the testes.

Uterus ventral to gonads, located in middle third of body, between anterior margin of testes and level of caecal bifurcation, approaching margins of body on both sides. Metraterm well defined, 101. Uterus contains a moderate number of operculate eggs, 46–49 × 19–21. Eggs possess one or two, sometimes more, polar filaments on each pole of the egg. Polar filaments consist of several fibres aưached/glued together. Excretory pore terminal. Excretory vesicle Y-shaped, with broad stem passing between testes and bifurcated at the level of the anterior margin of testes. Anterior ends of excretory vesicle arms reach ends of caeca.</paragraph>
