Nha Trang Bay: Mung Island, 15 m depth, boring in bivalve shell Pinna sp ., 1 specimen; Mot Island, 7 m depth, coral rubble, 7 specimens; Tre Island, intertidal, fouling community, 6 specimens. Description. Trunk 18–25 mm long and 3–4 mm wide; pale or grey, slightly glossy with semitransparent body wall, with brown dome-shaped conical papillae increasing greatly in size anteriorly and posteriorly; pre-anal mammiform papillae reddish-brown, much larger dorsally. Introvert 1.5 X longer than trunk with wide pigmented bands more prominent dorsally. Yellow-brown tentacles with black pigments at the bases around the nuchal organ. Hooks with clear streak separated from the distinct triangle. Longitudinal musculature splits into 20–23 bands. Dorsal and ventral retractors originate 50–60 % and 40 % of trunk length from the posterior end, respectively. Gut with 12–15 loops; spindle muscle attached posteriorly. Nephridia about 50 % of trunk length, about 2 / 3 attached to the body wall; nephridiopore and anus at the same level. Discussion. Morphologically this species is similar to P. albolineatum . In contrast to P. s c o l o p s , the hooks of P. albolineatum bent at an obtuse angle which is a unique character to this species.
