Polystira oxytropis is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids.^[1]

Description

The horn-colored shell contains several sharp keels and numerous spiral raised lines. The upper keel is the strongest, angulating the whorls, the surface concave above it. ^[2]

P. oxytropis is considered an "umbrella species" with considerable diversity as shown by DNA sequence data coupled with conchological studies. ^[3]

Distribution

This is an Eastern Pacific species, occurring off Western Mexico, in the Gulf of Panama and the Pacific coast of Colombia.
