Male reproductive system: about 50 testes scattered in 2-3 layers above one another in aporal portion of medullary parenchyma, from anterior margin to posterior border of the segment, aporally from ovarium and some also above it; they measure 0.028-0.037 x 0.030-0.040 mm. The testes atrophize concurrently with uteral development. Vas deferens decurrent anteriorly to receptaculum seminis, forming a vesiculum seminalis externa of varying size, surrounded by mucous cells, in front of cirrus pouch. In proximal half of cirrus pouch, it widens into a vesiculum seminalis interna (0.045-0.070 x 0.035-0.055 mm), then joins cirrus as a straight, narrow tube. Cirrus 0.075-0,110 x x 0.012-0.015 mm, covered with minute spines (about 1/*/) arranged in oblique rows.
