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 (Brown, 1827) is controversial. Both are tentatively distinguished by Reñas & Rolán in Gofas et al. (2011) and by Giannuzzi-Saveli et al. (2014).
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.
