The funnel-shaped part is 20,524 µm wide and its length is approximately 1/7 of the total length. The inner stylet is not restricted to the distal part of the outer stylet and even bulges out of the funnel proximally. The outer stylet does not carry any spines or hooks, but the funnel-shaped part is ornamented with a ring, which gives the proximal part of the stylet the shape of a stirrup. It is 2831 µm wide and 2128 µm long. The prostate stylet

The clasp is strongly bent and situated very close to the thickened, proximal edge of the plate, giving the whole the appearance of an eight-shaped ring. The inconspicuous foot is situated at the base of a thread-like flagellum, which is 8690 µm long (measured from the proximal rim of the foot). This flagellum shows a strong curve at ± 65% of its length, but does not bear a comb nor is its distal end swollen. The most proximal third of the flagellum is not free, but connected to the plate.
