Pyrgiscus rufus

Pyrgiscus rufus is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.

Taxonomy

Whether this species is distinct from Pyrgiscus crenatus is controversial. Both are tentatively distinguished by Reñas & Rolán in Gofas et al. and by Giannuzzi-Saveli et al..

Description

The shell grows to a length of 5 mm-9 mm. Shell: Elongated shell with 14 or less whorls., Reddish shell. Sculpture c. 20 slightly opisthocline axial ribs, with wide interspaces. Whorls are evenly rounded, tending to flat. The body is a clear pale-azure color, with irregularly spaced snow-white flakes.

Distribution

This species occurs in the Mediterranean Sea. Watson's record from Puerto Rico is probably not the same species.
