with a copulatory organ encompassing an armed cirrus, an unarmed accessory cirrus, and two distal hooks. Bipartite armed cirrus consisting of two sacs lined with a continuous ± 295.2 - μm-long sclerotized belt of overlapping scale-like spines. Larger sac with more spaced-out, triangular, ± 20.1 μm-long spines on the proximal end of the belt. Spines gradually decrease in size distally as the belt runs towards and folds into the smaller sac, increasing in size (± 6.1 to ± 22.2 μm long) towards the proximal tip of the smaller sac, and decreasing in size again from the proximal to the distal tip of the smaller sac. Unarmed accessory cirrus as an elongated sac. The larger distal hook is slightly curved, ± 111.5 μm long and ± 43.5 μm wide at its base; its base is provided with a slightly curved, ± 42.3 μm-long projection with a blunt distal tip forming a ~ 90 ° angle with the axis of the hook. The smaller hook is funnel-shaped, ± 58.9 μm long and ± 46.6 μm wide at its base.

The oesophagus is visible as a clear zone surrounded by oesophageal glands behind the pharynx. It empties into the intestine, which is situated in the posterior portion of the body. The male and female reproductive systems are mainly located in the third posterior region of the body.
