Odostomia pulchra is a small sea snail in the Pyramidellidae family. The white shell is about 2.2 mm long, oval and conical with a shiny surface. The early shell has 1.5 tiny turns that are partly embedded in the next turns. The main part of the shell has 4.5 rounded whorls with four spiral cords and strong axial ribs (14 on the second turn, 16 on the third, and 18 on the penultimate). The opening is pear-shaped, the outer lip is thin, and the inner lip (columella) is slender, curved, and has a weak fold where it attaches. The shell’s base has four broad rounded keels separated by slender ridges. This species is found in the Pacific Ocean off Margarita Island, Bay of Panama.
