Description

The height of the shell attains 6.7 mm, its greatest diameter 13 mm.

(Original description in Latin) The shell has a somewhat conoidal-depressed shape. It is moderately solid, slightly wrinkled-striated and punctuated, shiny, and reddish. The spire is somewhat conoidal-convex with a fine apex. The shell consists of 4 whorls. The upper whorls are rather flat, while the body whorl is broad, depressed, and somewhat rounded at the periphery. The aperture is diagonal and broadly semi-oval. The columella descends vertically from the penultimate whorl, is slightly curved, and ends anteriorly in a tubercle, emitting a somewhat granular, circumscribed basal callus. The peristome is shortly expanded with a white border. The operculum is of the same color.

Distribution

This species lives in Haiti.
