Lirapex has an unusual type of sculpture consisting of the lineate sculpture typical of peltospirids with numerous tubercles between them, especially near the axis of coiling. Both fade out about halfway to the aperture. When viewed from the bottom under the light microscope, a thick bar running across the shell is visible just posterior to the aperture. The aperture is nearly straight, with a wide rim tapering toward the posterior. The shell is transparent and glassy-looking.
