Pseudoliotia pulchella Dunker, 1860

Native status

Under rocks on sandy gravel bottoms in intertidal zones in sheltered areas.

Distribution

China, Japan.

Notes

Pseudoliotia Tate, 1898 is characterised by a depressed conical shell with strong axial and spiral ribs on its surface. P. pulchella is similar to P. astericus , but much larger, lower in shell height and with relatively weak axial ribs.

Diagnosis

Shell minute (1.3 ± 0.19 mm in length, 3.1 ± 0.16 mm in width), depressed conical, round pie, solid (Fig. 11 ). Whorls about 5, spire very low, body whorl large, the spiral layers are almost in the same plane, whorl periphery appears markedly truncate with a deep concave sulcus between the two peripheral keels. Suture distinct, grooved. Surface sculptured with thick spiral cords and many strong axial ribs, white or covered with yellow crust, thin sculpture lines on the sides of the whorl. Protoconch smooth. Aperture thickened, ovate, declining. Umbilicus deep.
