Diaugasma olyra is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Description.
The length of the shell attains 11 mm. It can be distinguished from "Diaugasma epicharta" by its much larger size, say 11 mm. long, a wider aperture, a shorter spire, and a pink-tipped apex. It is likewise semi-transparent, and the very delicate spiral striation across the whorls is represented by the Reeve as sometimes evanescent altogether.
Distribution.
This marine species occurs off the Philippines and Taiwan.
