Material examined: ESFM – SIP /98–36, K8, Limanbasi Cape, 20 July 1998, 0–5 m, on rocks, 3 specimens. Remarks: Body wall thick, not transparent, with irregular dark bands on introvert. Trunk cylindrical, 17.5–18.4 mm long, 3–4.9 mm wide. Introvert 16.7–18.4 mm long, 2.2–3.1 mm wide. Introvert nearly as long as trunk length. Longitudinal muscle numbering 24–26 on posterior part of trunk, 18–22 on anterior part of trunk. Papillae on trunk granular, dome­shaped; 240–290 µm long on anterior part of trunk. Hooks arranged in over 50 rings, some of them incomplete; with a narrow clear streak with an indistinct granular triangle; indistinct or no secondary tooth (Figure 4 B); 30–75 µm high, 43–70 µm wide at base.
