 Remarks: Body cylindrical or rod­like. Trunk 2–17 mm in lenght, 0.6–2.5 mm in width. Introvert 0.8–7.5 mm long, 0.3–1 mm wide. Trunk 2.3–2.5 times introvert length. Hooks yellow, dark brown. All introvert hooks unidentate; 13–53 µm long, 15–38 µm thick at base. Longitudinal grooves on anal shield numbering 15–20. Anal shields usually with spines. Radiale grooves on caudal shield numbering 16–20. Finger­like spines on introvert 10–38 µm long. Intestinal spiral with 11–26 coils. Nephridiopores located just posterior to anus or at level of anus. Some specimens with eggs in coelom cavity, elliptical; longer axis 48–95 µm in diameter, smaller axis 33–85 µm in diameter. A total of 8 specimens of parasites (ectoprocts) were found to be attached to the anal shields and the proximal part of the introvert of two individuals.
